Is there a difference in a 2.3 non vtec and 2.3 vtec head bolt pattern?
There is a difference in a 2.3 non-VTEC and a 2.3 VTEC head bolt pattern. Since the patterns are different, the engines cannot be switched without modifications.
How does the rad fan on a 1986 Honda Prelude come on?
There is a temperature switch on the passenger side bottom of the radiator that has a wire connector attached to it. The switch screws into the radiator and then the wires connect to that. That switch is what tells the relays to turn the cooling fan on. If your fans don't turn and the engine is running hot you can test the switch using the following steps. 1. turn the ignition to the on position but don't start the engine. 2. disconnect the wire connector to the switch on the bottom of the radiator. 3. using a small jumper wire, jump the two wires inside the connector. If the fans turn on then you will need to replace the temp switch. If the fans still don't turn on then you will need to check the fuses, relays, and the fans themselves.
Troubleshooting Procedures The trans control unit is under the carpet near the passenger's feet. The A/T Control Unit has a built-in self-diagnosis function. The S3 indicator light in the gauge assembly and LED display on the A/T control unit blink when the A/T control unit senses an abnormality in the input or output systems. The number of blinks from the LED display varies according to the problem, which can be diagnosed by counting the number of blinks. For problem diagnosis count the number of blinks from the LED display as shown on the Symptom-to-Component Chart on page 14-40. If no abnormality is found from your inspection, refer to the hydraulic system Symptom-to-component Chart on page 14-66. LED DISPLAY S3 INDICATOR LIGHT When the ignition switch is turned ON, the S3 indicator light comes on for about two seconds regardless of whether there is a problem. The S3 indicator light will also come on when in S3 mode. If there is a system problem, the S3 indicator light will come on and continue to blink until the ignition key is turned OFF. When the ignition key is turned ON again, the S3 indicator light will not blink again for the original problem. But if the A/T control unit senses the original abnormality again with ignition switch ON, the S3 indicator light will blink again for the original problem. Therefore, even though the S3 indicator light does not come on when turning the ignition key ON, check the LED display for automatic transmission problem diagnosis. Since the LED problem code is retained in memory, it will blink again whenever the ignition key is turned on. If the LED problem code is not memorized, check the following causes: Check the EFI ECU fuse No. 35 (10 A) in the under-hood relay box. Check for an open circuit in the WHT/YEL wire between the EFI ECU fuse No. 35 (10 A) and A/T control unit B12 terminal. After making repair, disconnect the EFI ECU fuse No. 35 (10 A) in the under-hood relay box for more than ten seconds to reset LED display memory.
Defective ignition switch or tumbler dirty or defective. Start by spraying a good electrical cleaner inside the key tumbler. Work it back and forth.
Where is the vss speed sesor located on a 1996 mercury sable?
ON my 96 Sable the VSS (Variable Speed Sensor) also known by OSS (according the the book I bought at Autozone) was located on the top of the transaxle near the driver's side front wheel. Standing beside the car's front left wheel and looking over into the car the sensor will be located on the top, backside of the transaxle and below the shifter location sensor. The easiest way to explain this is that is't located just below all the other stuff on the top of the transaxle but right on top of the transaxle. Just has one small bolt beside the connector toward the front of the car that held it in place. Hard to get to. Had to partially loosen from the top of the car and complete using a long 1/4 extension from beneath the car near the wheel. Note: The sensor on ours looked NOTHING like the one in the book. It wasn't in Autozone's or Oreilly's computer or the Wells picture book as of this entry. We were able to crossreference the part number on the sensor itself to a OEM part number OEM Brand Ford SS10697. (the part number on the sensor was F1DP 7M101 AA). Still looking for the part at the moment. The one in the book was long and black with a round white thingy in the end of it. This was a mechanical type. Our was a magnetic type which basically looked like a place to attach a connector on the transaxle wall. The wiring connector was a two sided clip that plugged into the sensor connector which faced the rear of the car. To sum up.. the sensor inserts into the transaxle straight from the left side of the housing and toward the center of the engine. The sensor Connector faces the rear of the car.
Can an amateur change the starter in a 1987 Honda Prelude 2.0SI?
Yes. An amateur can change the starter. The long bolts must be removed, the wiring disconnected and the starter will come out. You must disconnect the battery's negative cable (black) during removal and replacement. It should be the first thing you do and the last thing you do. You need the right tools, patience, and you will have to remove some things to get to it. Be sure and make an area to lay things as they come off so you can reinstall in the same order that the parts come off. If you are careful, the job shouldn't take more than 2 hours. Take off the old one and take it with you when you go to the auto store to buy the new one (for comparison). Good Luck!

Yes I put a 240sx coupe bodykit on my 91 prelude. the only problem i had was the sideskirts wiere 1/8th of an in shorter. but fit like a glove
It keeps you legal and directs the exhaust fumes to the rear of the vehicle.
Cooling fan not working? Water pump not working Radiator plugged Hoses collapsing Airbound Cooling fans do work. Like when she is on the hwy, she's fine. Stop & go stuff really gets to her. Also, she may run fine one insance, then if I shut her off and restart her the overheating begins, thenEngine overheats When a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage. First, with the engine cold, make sure the radiator is full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system. Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant. If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on. Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out. Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transfering engine heat to the coolant. Remove it and have it 're-cored'. One of these steps should solve the problem. after fiddling with the fluid levels, shutting her off and starting a few times she is right. Any ideas??
Where can you find a wiring diagram for a 1997 Honda Prelude?

If a Honda has 242000 miles would you replace the timing belt?
"Interference engine" means pistons will hit valves if the timing belt breaks. A high-lift cam, which pushes the valves closer to the pistons, combined with a high-compression engine, which pushes the pistons closer to the valves, equal an engine that is either always an interference engine or just an interference engine if there's enough carbon and schmutz on the valves and piston faces. Sometimes you break a timing belt, put a new one on and all is well. Sometimes you break one and wind up having to change valves and pistons.
As far as I'm concerned, head gaskets are inexpensive enough that it won't hurt you to pull the head and inspect the valves and pistons if you're changing a broken timing belt. Not only will you KNOW the engine will start when you put it back together, it'll make setting the crank to TDC much easier.
AnswerI just had the timing belt replaced on my '89 Honda Accord it broke while I was going down the expressway. My mechanic told me I was one lucky guy as it is an interference engine and he expected at least one bent value but non were bent. My advice is to replace it before it breaks. Its a $350 job but if you break it while driving you can add another $100 for the tow plus another hundred or so to determine if there are bent valves. If there are bent valves the price goes way over $1000. I had less than 80,000 miles on this belt.Just a PS. this is NOT an interference engine. You will not have bent valves, damaged pistons or any other such problem. Camshaft and Crankshaft can be rotated individually without a problem. I have replaced many Honda belts, both before and after breakage.
the "interferance" , i don't know where you guys get that but that has no bearing on bent or non bent valves on this model. Interferance meaning the type of belt system, like the F series is interferance, because there is a balance shaft belt that turns 2 balance shafts ofn that particular engine , same as the H series. Now talking about being square , under square and over square , now that's more of a preferance of bending valves or not as Honda has always been larger bore or almost equal bore and hort strokes, making for engine capable of high rev,s these are under square engine. The possibility of bending a valve is high. But on these A20 engines as in these models with 3 valves , it was designed that if the belt broke the cam would and always usually turned to a "neutral" position to where most the valves were closed or near a closed position as not to bend valves.
Kongkit Raggan-Supatanampon
AnswerKongkit, "interference engine" has nothing to do with the belt system. If you've got an interference engine--Hondas do--the valves are close enough to the tops of the pistons that they'll hit if the timing belt breaks. A noninterference engine, like you'll find in a Toyota or a VW, has enough clearance that it won't hit.Given that, in reality the Honda engine isn't a "true" interference engine. They gave just enough clearance between the valves and the pistons that, assuming there's not a lot of buildup on the valves, you won't hit if the timing belt breaks. That's a really big assumption, and Honda is afraid of lawsuits: if someone was running an ill-maintained, crudded-up engine that Honda claimed was noninterference, broke the timing belt and bent four or five valves, their first stop would be a lawyer: "But they SAID it was a noninterference engine!" They cover their asses by claiming the engine is interference. This way you can be happy if you break a timing belt and not bend any valves, and you won't sue if you do bend a few.
If it was my car, I would pull the head and look. If you managed to bend a valve or hole a piston, it'll be very obvious. If you didn't bend one? You needed a new head gasket anyway.
to be safe you should change the belt every 50,000 to 90,000 miles
Answer:
Not if the previous owner just did it 10,000 miles ago! When was it last changed? If you know anything about your car, who you got it from, or better yet, where it was maintained, possibly they can tell you when the last one was done. Honda dealers keep good computer records, and you can go visit or call the service department there, take your VIN, and they can tell you whether they've seen your car before and what has been done to it and when.
Most likely the piston is hitting the valve. This can cause a LOT of damage. i have a 95 turbo, and it jumped time causing the balance shaft to hit the crank. this sounded like a piston hitting a valve I would suspect a Rod Bearing.If the Piston interferes with the Valves it would barely run,, if at all.It's fixing to "sling a rod"....
Does anybody know where I can find ECU codes for a 1989 Honda Prelude 2.0si FI DOHC?
There are many forums where this has been asked. just used detailed searches in google. Type something like "ecu flashing codes 89 prelude" in google. should get some good stuff.
I know 6 short flashes is temp sending unit.
There is a sensor on that car that tells it if it is cold or hot your car is not coming up to the cold idle speed. If you go to any auto parts store they will check the computer on the car it will tell you a code that will note which sensor.
Also check the idle screw on the intake. The tech at the auto parts store will know which one it is.
How do you set the timing on a 1992 Honda Prelude?
I can offer the timing procedure for my '87. Timing is done with the engine running (non-static method). Hook things up, check to make sure no wiring will get caught while you're using the light and adjusting the distributor. DON'T DO YOUR FIRST TIMING UNTIL ALL ITEMS ARE SET UP AND YOU'VE CHECKED TO MAKE SURE YOU WONT GET SOMETHING CAUGHT IN THE MOVING PARTS OF THE ENGINE. BE SURE ITEMS SUCH AS NECKLACES, BRACELETS, HAIR, CLOTHING, OR WIRES ARE REMOVED OR TIED AWAY FROM THE MOVING PARTS OF THE ENGINE. WARM UP ENGINE AND OBSERVE MOVING PARTS. WHEN ENGINE IS WARMED UP (RADIATOR FAN COMES ON), TURN OFF ENGINE. DO HOOKUPS AND VERIFICATION FOR SAFETY. START ENGINE AND BEGIN WORK SLOWLY, CAREFULLY. A timed engine will "hum" and make your car fuel-efficient. Don't rush. It's not complicated but this needs precision on a running engine. BE CAREFUL. SAFETY FIRST! Timing is done with a timing light shined on the timing mark on the flywheel while the engine is running. The timing mark is located on the flywheel. To see it, there is a small "porthole" about 1" square covered by a square rubber plug. The hole/plug is located on the FRONT of the engine, about 4" from the centerline on the passenger's side. It's down about 5" from the #3 or #4 spark plug. When you pull off the hole's black, square plug: There are three colored marks on the flywheel. You may not see them until the flywheel is rotated or the car is running with the timing light shining on the "pointer" in the hole. THE GREEN MARK IS FOR TIMING. The Red is top-dead center. The White is ???? There is a pointer visible thru the hole which is the alignment item used to align the green mark. The adjustment for the timing is done by rotating the distributor (you must loosen the distributor screws a little). Timing should be done with the engine at the right idle speed, so be sure the tachometer is checked after the car is warmed up (my idle speed is around 750-800 rpm). Your idle speed will be specified on the underside of engine hood, on a sticker showing emissions information. The distributor is to be moved with a little friction from the holding screws so that it doesn't change after you set it and before you tighten one of the screws. Check the timing again afterwards to be sure the distributor wasn't moved during the tightening procedure. So CHECK THE DISTRIBUTOR FOR MOVEMENT BEFORE THE ENGINE IS RUNNING. Tighten/loosen at least one of the screws so you can move the distributor but not allow the distributor to change position after you get the timing right. FOR OTHER SETUPS: The timing mark is often located on the end of the engine(near distributor)on the passenger's side, near the main belt pulley. This 5" round pulley probably has all the accessory belts on it (usually three belts) and is located about 12" down from the top of the engine. There is a notch on the pulley that is used as a match-up mark to the mark on the engine block ABOVE the pulley. The mark on the engine is likely about 3" by 1" square with lines on it--perhaps even the numbers indicating the degrees before (or after) top-dead center. Either way, if the specified timing is 15 degrees BEFORE top-dead center, then look for the line with a "15". In this example there might be a "20" on one side of the fifteen, and a "10" on the otherside. MARK THE PULLEY WITH WHITE-OUT, WHITE PAINT, OR CHALK so you can see it when the engine is running. FOR ALL SETUPS: TIMING LIGHT: The timing light is hooked up to the battery (red/black clamps) and the #1 SPARK PLUG WIRE. Be careful before starting engine that the slack in the wires doesn't get caught on moving parts. Once the car is running, point the timing light at the white mark on the pulley. The timing light strobes on/off with each electrical pulse given to the #1 spark plug wire. While pointing the light, you move the distributor, slightly at first, left-right to watch how the white mark moves back and forth in front of the engine mark-lines. If the distributor is too loose, turn the vehicle off and tighten one of the screws a little and see if the distributor has some friction when moving it. Once the distributor has the timing mark aligned with the pointer or engine mark, then tighten one of the distributor nuts (not too tight) and use timing light to recheck. If the marks don't align, then loosen the distributor and realign; tighten, then check. Turn off engine. Tighten distributor. Start engine, recheck marks and if OK, TURN OFF ENGINE. Loosen all the timing light wires and remove from engine compartment. If you do this while the engine is running, you'll have a good possibility of catching one of the wires in the engine (bad scene). CONSIDER a valve adjustment after the timing if you want. Some vehicles have one or two vacuum hoses or electrical devices disconnected while doing the timing.
Where is the transmission filter located on a 1989 Honda Prelude 2.0 Si?
Most Honda transmission filters are located inside the transmission and are a non-serviceable item. The transmission must be removed and broken apart to replace the filter. The filter never needs replacing and is considered a lifetime filter. I have an '87 Prelude and checked both my manuals and saw no reference to a filter for either the manual or automatic transmission. I checked the exploded drawings and the maintenance chapter for some reference to a maintenance cycle for the transmission filter. I FOUND NO REFERENCE AT ALL. The preceding answer is probably correct but I wonder if this "permanent filter" is a cause for damaged transmissions. I have the impression that Honda transmissions have a higher-than-normal number of problems. I can't help but wonder if it's in part due to a non-replaceable filter. Also, I wonder if it might be a good idea to place a large magnet on the bottom side (not bottom) of the transmission housing so as to attract metal particles. If magnets are already installed as a factory item (highly likely) then another magnet may help. This may require the use of an epoxy to as not to knock the magnet off. Check on other references about this first.

How do you remove a starer motor on a 1988 Honda Prelude?
disconnect your batter first. then take the 3 wires off.... then the three bolts and u should be done
What are the timing marks for a 85 Honda Prelude?
On a 85 prelude manual 5 speed there is a small square opening (approx 1 1/2" X 2') on the transmission housing where it mounts to the engine block just below and to the left (when facing front of car) of the number 4 spark plug. Look inside this opening and you will see the flywheel, the 20 degree BTDC mark is on the flywheel. There is a small needle shaped pointer on the engine block. Adjust the distributor so the timing mark on flywheel is in line with needle pointer. Since you asked where the marks are I assume you know how to time the engine. I.E. warm engine, plug vacuum hose at distributor, loosen and rotate distributor for your advance/retard.
The timing mark on flywheel may be dirty, I had to remove the flywheel cover under my engine by oil pan and hand crank engine counter clockwise with socket on the front of the crank inside fan belt pully to clean my flywheel. If fan belt pully bolt becomes loose, torque to spec and don't forget to remove socket from bolt when done cleaning and before you start engine....
Where is the EGR valve located on a 1998 Honda Prelude?
If it is a v6, it is located next to the distributor. Facing the engine it is on the right side of fuel injectors just under injector cover. You can see it from the drivers side.
Another Location in 1998 Honda preludes for the EGR (at least in mine) is at the top left of the engine block, just behind it. Here's a crude Diagram.
........................Big Silver intake valve here
EGR here
