Where is the radiator drain plug on your Honda Civic 1991?
I found it! It's a little, white, screw on plug which is only visible if you look under the radiator from the passenger side of the car.
When your engine is cold add coolant to the coolant reservoir so it is up to the cold
mark
You accidentally poured motor oil in your radiator?
You need to have the radiator flushed immediately
How do you bleed or burp air from the engine cooling system on a Ford Windstar?
First a caution: NEVER ever think of releasing a radiator - coolant cap when the engine is hot, or even warm!!!
Burping: In order to what is sometimes referred to as 'burping' the cooling system - getting a big air bubble out of the closed cooling system, and IF the car has a radiator cap,you will actually need to have the car running with the cap off.
- During the initial fill, fill the coolant reservoir bottle to the top of the cold fill range.
- Set the temperature blend selector to the full warm position and the fan motor control to high for the front and rear heaters
- Start the vehicle with the reservoir cap off and allow to idle until the thermostat opens
NOTE: the coolant level will drop quite a bit when the thermostat opens - that's most of the air bubble in the system being driven to the top of radiator and escaping. Without the air, there's more room for coolant.
- Top off the coolant in the reservoir bottle to the top of the cold fill range,
- Install and tighten the reservoir cap.
- Increase the engine rpms to 3,000 for 15 seconds, and then return to idle for one minute.
- Repeat the previous step four times or until heat is coming from the rear unit while the vehicle is idling.
- Allow the vehicle to cool and top off the coolant in the reservoir to the cold fill range.
Note: if you find the heater going cool or cold when idling, that's a good indicator you might have to burp the system again. Equally likely just adding more coolant to the overflow reservoir will suffice too.
Did I mention to NEVER ever think of releasing a radiator cap when the engine is hot, or even warm? !!!
This is the best ever clue to burp the system and I still had problems with air bubbles. I finally got it to quit blowing cold air due to air in the cooling system.
1 - Do it like the person above advises
2- Open up the radiator cap while it is still cold start the motor and when you see the coolant flowing after the thermostat opens. stick a long funnel into the filler neck because the fluid is going to overflow in a hurry.
3- The long funnel is going to capture the fluid and when it goes up your funnel then it's going to drain back into the radiator you may loose some fluid due to overflowing the funnel because it's going to belch about a half of a gallon or more - so be prepared to immediately pour some more antifreeze back down the funnel to keep the radiator full and keep the air out when the water pump moves the fluid back into the motor. At all costs keep replenishing the fluid when it belches air and fluid out of the radiator into your funnel or air will get back into the motor and will defeat your attempt to keep the air out.
4- You have to do this 2 times to rid the system of air before it works so wait for the thermostat to open again and repeat pouring fluid back into the system. Don't piddle around while doing this because once the water pump sucks air in the radiator because your not pouring the fluid back in fast enough and your not going to belch it.
Have a friend to help you get ready to pour antifreeze back into the radiator when it cycles. I had a catch pan under the car to catch the spilled fluid and reused it to pour it back in after the first belch so your friend can put that into a container to get ready to fill the funnel into the radiator again on the second belch.
5- no matter what - DON'T let the radiator level get low at any given time!!! keep pouring in the fluid fast as you can to keep the radiator completely full so it will have no air in it when the thermostat opens and cycles fluid through the water pump.
6- Wear safety glasses because fluid will spill and hit the engine belts while it's running and it will fling fluid everywhere.
It took me several attempts experimenting how to purge the system and this way I found definitely works for me and never had a problem since. I worked for Ford as a line mechanic for several years and this windstar is the meanest system I've ever purged. So if you ever have to change your antifreeze and drain the radiator and engine block this is the way I found to purge the system of air successfully... Thanks to the fellow above on his advise it helped out a lot.
I'm going to give you some more hint's that lead to this problem.
Look at the bottom side of your radiator cap you'll see a rubber washer mounted under the spring cap. If the rubber gets larger than the cup it's mounted on it will seal against the neck and won't let excess pressure escape from the cooling system effectively nor will it let fluid return into the radiator from the reseroir - so you'll need to buy a new one but WATCH-OUT even the parts stores will sell you a new one with the rubber sticking past the cup it's mounted on (The ones made in Mexico are the bad ones to buy) Just make sure the rubber is a little smaller than the circumference of the cup it's mounted to and you'll be alright... This applies to all vehicles and equipment new and old.
I've found parking your windstar on a kind of a steep hill with the drivers side higher than the passenger side will force the air in the heater core and the engine to release air in the system through the thermostat a little quicker and is more effective in purging the system...
What is the proper procedure to flush the radiator system on a 2001 Nissan Sentra?
First you must disconect the smaller hoses, then the one on the top left then top right. When you disconect the small hoses expect fluid to leak out, so get a large container. Same for the larger hoses. Then put the emergency brake on (just in case) and start the car, but make sure there is something under the engine [preferably towards the front] to catch the fluid. Be sure to rev the engine a couple times. After about 30 seconds shut the car off. Now use a hose and spray it into the radiator where the cap is located. Finally re-connect all the hoses and re-fill the car of engine coolant and if its front wheel drive you will also need trans fluid.
Here is advice: * The best thing to do it to take the radiator to a repair shop and let them handle the repair. They will clean and flush it and repair any leaks. It may be almost as cheap to replace as to repair. Check on the price of a new radiator before paying for a repair. * Most modern radiators are aluminum and plastic composite. They are not economically repairable and therefore should be replaced. NEVER replace the radiator without new hose, new radiator cap and new coolant. A new thermostat is recommended. NOTE: Unless damaged, the chief cause of radiator failure is actually a blown or leaking engine head gasket allowing the cylinder pressure (80-125 PSI to leak into the radiator (max 20 PSI).
diesel has a lower boiling point than antifreeze. as the engine heats up the diesel will vapourize and cause high pressure in your system. you will also has much worse temperature control in your engine.
First check connections on the radiator temp sensor. Then check the fan operation by applying 12 volts direcly to the harness connector. If the fan operates, you need a new cooling fan relay. The fuse hardly ever goes but it's worth a check.
How much anti-freeze do you need to fill an empty radiator in a 1993 ford explorer?
Four quarts of anti-freeze mixed 50/50 with four quarts of preferably distilled water should do the job, you may have some left over.
What happens if you accidentally put oil in the coolant?
First, if you've added oil to the radiator or to the coolant reservoir but not yet started the engine, you should be able to remove almost all of it. Using anything from a pump to a syringe, suck out all the oil you can; being lighter than water it should be floating on top of the coolant. Once the engine has been run, some of the oil may have circulated and become unreachable. But go ahead and remove any oil possible. The radiator has a "stopcock", or valve, at the bottom. If you drain, fill, and drain the radiator completely a couple of times, most of the oil should rinse out. (Be sure to refill both the radiator and the coolant reservoir!) Then, when you think most of the oil is out (and the radiator is full with water or coolant!) it's best to drive to a nearby garage and explain what happened. They can perform a reverse flush under pressure, hopefully removing all the contaminant. (If no one nearby can service your radiator, and you've not been able to remove most of the oil, you may wish to have the vehicle towed.) One problem with oil in the radiator is that the tiny channels through which water travels and carries away engine heat can become clogged with the oil. The result could be a seriously overheated and damaged engine. Another problem is that the oil can cause premature breakdown of hoses or seals.
Where is the radiator drain plug for a '02 Chevy Impala 3.4?
== == It is located at the lowest level of the radiator, and it looks like a miniature water tap. Be careful not to try to drain it when the coolant is very hot, you could get burned. You will need a very large container to hold the coolant, at least 6 gallons in size.
Where is the radiator drain plug for 200 Nissan altima located?
On the bottom of the radiator, driver's side. It's a plastic phillips-head screw.

Where is the radiator in a car engine?
Very front of the car while hood is up behind the large fans when looking down.
Where is the radiator petcock on a 2000 Grand Marquis?
plastic valve on driver side on inside of radiator
If there's transmission fluid in my radiator how do I fix it?
The transmission oil cooler built into the radiator has gone bad. There is a good chance engine coolant is also getting into the transmission. This is a serious problem. Do not drive the car any further. Have it towed to a garage to replace the radiator and flush both the cooling system and the transmission. Good luck.
Where is the drain plug for the radiator in a 1999 Chevy Malibu?
Hey Jim==(It is on the bottom right of the radiator. Sometimes it is easier to pull the lower rad hose. Save and dispose of the used coolant according to the epa. goodluckJoe
What oil weight should you put in a 2000 Nissan Altima GXE w 63000 miles?
This information is listed in your owner's manual. Get an owner's manual from the dealer or a salvage yard.
That sounds like the crankcase vent hose, It should be attached to the top of the crankcase and go backward then turn toward the ground,If That's the part your talking about, It will not connect to anything but the motor only on one end, The other end should be left to hang and free from obstruction,
If that's not it Sorry, and ask again.
Where is the radiator on a 1999 Plymouth Breeze?
Should be right behind the front grill - behind the condensor if it has A/C
Where is the location of a radiator drain on a 2000 Isuzu trooper?
Look at the bottom or rear side of the radiator
If there is oil in radiator not in block what is the problem?
Without any other info I'd say you have a bad headgasket or a cracked head/block.
Generally oil has to be pressurized to show up in coolant, or the reverse would be true and you'd have coolant in the oil also making it milky white.
So... oil is leaking from somewhere pressurized to coolant.. Pressurized oil only comes up to the head in one passage, and that has likely developed a leak to the nearest coolant passage, most likely through a bad head gasket.
This is more likely if it's been recently overheated.
Some vehicles have an internal oil cooler located in the radiator. If this cooler has a leak then you will get oil in your radiator. If the fluid inside the radiator is a pinkish, reddish color the it would be the internal transmission dooler in the radiator
