How to install radiator bottom hose?
remove the old one by loosening the screw clamps and sliding them down the hose, then pull on the hose with a twisting motion. Do NOT yank side to side as you can damage the radiator this way. If it is stuck *carefully* cut a slit in the hose (not too deep you don't want to damage the outlet, the radiator is only plastic there) from the end about 1-1.5" in and peel the hose off the outlet.
Compare the new hose to the old one to make sure it is correct, then slide the new clamps on each end, putting them at least 3-4"down the hose to keep them out of the way. Guide the new hose in place, then slide it onto the outlets at least as far as the old one was. slid the clamps to about 1/2" from the ends of the hose and tighten them until they are snug.
Once you've refilled the system and started the engine, watch for leaks and tighten the hose clamps as needed.
How do you drain radiator on a 97 Mazda Millenia?
You would remove the radiator cap to ensure smooth flow.
Put a pan or bucket under the radiator to catch the coolant. Please make sure you don't spill any, or clean it up if you do. Antifreeze tastes sweet. Cats, dogs and other animals are very attracted to it. It is fatal when they drink it. For us too.
There should be some kind of a draincock at the bottom of the radiator. Open it to drain the coolant. Flat pliers or similar tool might help opening the draincock if it is stuck, but be very careful not to break it. They are made of plastic and can become crisp with age.
If the draincock doesn't seem to open (or you might break it), you could, as a last and rather messy resort, open the clamp around the lower radiator hose and hope that the entire content of the cooling system doesn't escape all at once. Have a wide bucket ready!
Be aware, you cannot the drain the radiator without draining the entire cooling system because it's all connected. When you refill the system, please follow the procedures as described in the answer to "How do you bleed the coolant for a 1998 Mazda Millenia?" This will avoid bad and costly surprises with an incompletely filled cooling system.
on the millenia, the drain is on the passenger side of the radiator. you have to look from underneath, you will see an access hole in the splash shield. a large Phillips screwdriver is used to loosen/remove the drain plug.
How do you fix a radiator leak on a 2000 Jeep Cherokee?
I have a 2000 Jeep Grand Cherokee I am not sure if a repair can be made. Today my 3rd radiator is being installed. There appears to be plastic and alum that join together sort of a crimped joint. This is where my failures occured. The first was under my extended warranty. The second occured 3 months after the first. So it was still under the second installation warranty. At one time the Radiatior was all alum and leaks could be easily repaired. They may have needed to be taken out but not replaced with a new one each time.
I like my Jeep Cherokee. It appears that the coolant system, brakes, and air conditioner seem to be it's weak points.
Where is the radiator drain plug on a 1999 Chevy Blazer?
its on the left hand side of the radiator but not very easy to get to My apology, it is a 1996 S10 Chevy Blazer instead of a 1999 Chevy Blazer. I need to see a picture or more detail of where the drain plug is located on the left side of the radiator. I have searched and searched and cannot find anything to drain with. Thanks, Linel
94 Camry no heat but car overheats new water pump thermostat and radiator?
Be sure the thermostat is not installed backwards.
How do you wire a '95 Monte Carlo's fans back up?
Well, I quess "plug the connectors back in" doesn't cut it, so, here goes: The fans are controlled by 2 relays that are located in the fuse box mounted on the right fenderwell. The fans get their power from the relays through the light blue wire from relay 1 to fan 1 and the white wire from relay 2 to fan 2. The black wires on both fans are ground If the relays are dead, they get their power through the red wires from the 2 60amp maxi fuses in the same box. Note: The Powertrain Control Module (PCM) activates the relays by "reading" a signal from the engine temperature sensor. A malfunction in this system will show up as a fault code P0117 or P0118 and the fans will not operate properly Hope this helps
Where is the radiator drain cock on a 1999 GMC Savana van?
Check on the bottom of the rad, it should look like a winged nut.
my 2000 GMC Savana 2500 5.7L doesn't have one .
I assume you submerged the starter. Remove the starter and place it in an over set at 150 degrees. Leave it for 12 hours. I should be throughly dry by then. If after this it does not function, replace it.
Where is the radiator drain plug on a 1991 grand am 2.5?
The 1991 Pontiac Grand Am radiator drain plug can be found on the bottom of the radiator. The radiator drain plug will be in the center of the radiator bottom.
Where is the radiator drain plug located in a 1998 Chevy Lumina?
drivers side on bottom of radiator it is plastic and on mine it is light green
Why do i have oil in the cooling system of your car?
Most likely blown head gasket, is there a mayonaise like deposit underneath the oil filler cap? That would indicate there's water in the engine oil too which just about confirms it. If the head gasket has gone its best to get it fixed quick as you can do more expensive damage as the car will overheat. ..or of course some idiot has put oil in the radiator by mistake in the past.
Why is a car overheating even after changing the water pump and the radiator?
Always should replace thermostat at same time; if this was not done, do so. Rust and gunk in the cooling system from a corroded radiator will often jam and damage the thermostat. Conversley, sometimes a corrding thermostat sets of the entire process by both stricking and by sending hicks of rust to the other cooling system components (radiator and water pump). After engine idles for a while (but prior to overheating) gently squeeze the large hose attached to the top of the radiator. Is it getting warm? If not, the thermostat is likely not working. The thermostat should click and open the route for the top radiator hose, when the temp gauge is no farther toward "H" than at or just below the halfway mark, or just above, on most vehicles. Once the thermostat opens up the route for the upper radiator hose, the temp gauge should fall quickly. If the thermostat wasn't replaced, appears to not be functioning, and is easily accessible and visible, tap it with a hammer (not hard enough to damage it)and see if it becomes unstuck. If your vehicle has an electric fan, make sure it is coming on after a few moments. If it isn't, check that its fuse is OK, that the wire connections are solid, then check that the fan relay is not burned out. A heat sensor sending unit which controls activation of the electric fan could also have failed. In some 60's vintage vehicles, one could often stop overheating by replacing the stock 4-bladed fan with a 5-bladed fan. If you have an automatic transmission that is routed through your cooling system, and you've tried everything possible to correct overheating, your tranny may be on its way out. The problems your tranny may be having having operating normally could be effecting the engine temp. I agree with the changeing of the thermostat , Here is one more sug your radiator cap is not maintaining proper pressure get it pressure tested IF YOU DIDN'T CHANGE THE RADIATOR CAP WHEN DOING ALL THAT OTHER STUFF, GO AHEAD AND CHANGE IT. IF THE OLD ONE IS BAD IT WON'T HOLD THE PROPER PRESSURE AND THE COOLANT CAN BOIL= OVERHEATING! patricklaw1957@yahoo.com Check the fan to see if it's running. If the engine heats up and the fan isn't going, the fan motor is shot. If you have tried everything else and you are still having overheating problems you might have a bad head gasket. I didn't see what type of vehicle you were working on. I had a 1988 Dodge Caravan. I replaced everything in the cooling system including putting an oversized radiator in. The problem turned out to be a bad head gasket. I never observed any oil in the radiator. If the thermostat was replaced and water pump and radiator as you say then there are only a couple things that it can COMMONLY be.It always seems to me that people like to take out the engine before replacing the spark plugs.Take theese words of advice(alot of people over analyze things)99 percent of the time it's the easy stuff!your problem is probably the radiator cap.If it is not holding the proper pressure it will overheat.cost is about 4.95. could be bad head gaskit
What would cause the engine not to reach normal operating temperature?
but only temporarily.
A thermostat functions to regulate the flow of water between the engine and radiator.
On an average outside temperature day (75 degrees), "no thermostat" would result in (1) the engine not reaching operating temperature in the normal engine warm up cycle time and (2) much later in the cycle the engine would overheat caused by the water not remaining in the radiator long enough to cool down. More extreme outside temperatures would impact the previous results.
No thermostat or a defective thermostat that is stuck open. Also could be a deffective coolant temprature sensor. Or air bubble aroune the sensor on some cars.
What might be the problem if there is ice under the radiator cap and the motor is overheating?
It sounds like the antifreeze / distilled water mixture is freezing because
the antifreeze mixture is too weak for the outside temperature
Usually the antifreeze and preferably distilled water mixture is 50 / 50
( Ford states to not exceed 60 % antifreeze )
have the engine timing checked. if the timing is wrong the engine will overheat, are you loosing coolant?is the fan working, is the water pump working?
How do you know if it is a radiator leak?
For radiator leaks look for the following signs: The car will overheat Coolant level will frequently drop Pool of coolant or water under the car radiator Obvious leak noted from radiator on starting the car Faulty radiator cap causing the leak
I am Trying to bleed air out of a 2000 Chevy impala radiator?
This should happen automatically. Are you losing coolant, is the cooling system leaking somewhere? Have you just changed the coolant? Unless there is a leak, the system should purge by itself.
Where is the drain plug located on a 1996 Monte Carlo?
There is only one drain plug and it's on the bottom of the oil pan, just like in every other car around the world.
What causes engine of corrado vr6 over heat?
The Vr6. Like the Foreigner classic, the vr6 is "HOT Blooded!" 220 is about average temp."Check it and see!"
Water leaking from passenger side of motor has water pump gone bad in a 1993 Saturn?
this is quite possible. the water pump is the only soruce of water on the passanger side of the engine. there are the coolant hoses running to your coolant bottle that could be leaking, or your coolant bottle itself could be leaking. these are usually not the case. water pump installation is accually quite simple. you can follow these steps if you plan on doing the repair youself.
1. jack the vehicle up on both sides, use jack stands if possible.
2. Remove Passanger front tire, along with plastic splash shield
3. Drain coolant
4. With serpentine belt still installed, loosen the 3 bolts on the water pump pully, don't take them all the way off, just loosen them.
5. Use a 14mm wrench to reduce tention on the serpentine belt enough
so you can slide the belt off
6. Remove the water pump pully bolts, remove pully, or let it rest on the
pump shaft.
7. Remove water pump housing bolts (6 of them) and discard the gasket
8. reverse procedure to reinstall new water pump
Where is the 2001 - 2004 dodge stratus radiator drain plug?
Lower pass side of side tank, very hard to access.
this advise should be concider as an opinion.
depending on how you purchased the vehicle the manufacturer will make their desicion.
perhaps you had the vehicle serviced by an auto shop that isn't lisence by Chrysler and therefore you voided your waranty.
or the vehicle was purchase used and the above problem was an issue.
or the vehicle was savage.
if they wont change it , you may have to have it change at your own cost.(don't go to a dealer)
How do you flush the radiator on a 96 contour and where is the radiator flush plug?
I have a '95 Contour but I'm sure it's the same for a '96. Firstly, there isn't a drain plug for the radiator. Sorry. But you can drain your radiator and coolant reservoir. When looking at your coolant reservoir or expansion tank, there will be two hoses that come out. One top and one bottom. Follow the bottom hose down to a conjunction of 3-4 hoses. There will be a hose that exits the bottom of the conjunction and runs under the car going towards the back of the car. It will be a fairly large hose with a hose crimp on it. undo the crimp and slide it back and CAREFULLY pull the hose off the tube. It will probably blast straight into the frame so be prepared. After letting all the fluids drain, You can reconnect the hose and run a radiator cleaner or a radiator flush through your radiator using your expansion tank. I would advise while you have everything drained, disconnect the two hoses from the reservoir and unbolt it from under the hood, and then clean it out. When I did it, it looked like a mix of mud and sludge coming out. Sorry for the long answer, but hopefully it's thorough and helps someone out.
