Question about 2002 Chrysler Town & Country

1 Answer

I have a chrysler 2002 3.8L T&C. The radiator fans are not coming on all the time and sometimes the engine gets a little on the warm side. It hasn't overheated yet but we did stop driving it until we get the problem fixed. To fix the problem I first replaced the temperature sensor located on the firewall side of the thermostat. This did not fix the problem. Next I replaced the fan relay located on the steel bumper between the plastic bumper and the radiator. The fan still does not come on all the time. I do not have an error code and even when I turn on the A/C the fans still dont come on. Is this the correct location of the items I've replaced? Could this some how be the thermostat? I am frustrated because I just got the transmission rebuilt and as soon as I got the vehicle back this happens. I figured that I could go through these items myself but the problem still remains. What should my next move be?

Visually inspect the air conditioner condensor on the front of the radiator as well as any exposed radiator on the front. if it has a large number of embedded bugs this could lower the airflow and allow the vehicle to get warm, a quick fix for this is to use a water hose with a sprayer and clean the bugs out or you could use a car wash wand on rinse, just do your best and see if this makes a difference.

could also be a sticking thermostat like you mentioned in your post.
hope this helps.

Losing water causing overheating


My first question is make model and year.
Second, are you saying the engine is boiling over into the overflow tank and onto the ground ? Is the tank about half full when the engine is cold ?
Have you run the engine with the thermostat removed to test ?
Usually when you can hear the coolant moving around, you have air in the system and it is not full of liquid coolant.

My 2003 chrysler 300 m special is over heating. the water level says its got plenty of water. the temperature gauge will drop when i turn the heater on


Coolant in the resevoir doesn't tell you what is in the system,
if you don't have vacuum when the engine cools off.

Do you have coolant flow thru the radiator,is the
thermostat stuck?

Are the fans coming on?

2000 JETTA OVERHEATING AT FIRST IT WAS LOSING WATER SO WE REPLACE THE HOUSING PIECE ITIS PLASTIC AND WAS CEACKED. nOW ITS JUST GETTING HOT NOT LOSING WATER


Your water pump impeller has probably come apart, you will have to do a timing belt job to get a new water pump in there. If you are not comfortable with that, take it to a shop. But yes, to check for water flow, pull the return line on the coolant bottle (little one on the top) and hold it so any water that would come out would go into the bottle, and start the engine (the engine has to be cold to try this test) there should be an almost immediate flow of water, if no water comes out, even if you give it a little gas, (should be a decent flow, not a trickle) than your water pump is in fact dead, very very common problem on 1.8 & 2.0 Jetta's, Beetles, and Passats.

Passenger side radiator cooling fan stopped working


I found that for some reason if you start your car and then remove and reinstall the hi and low relays that the fans work. I have done this numerous times on my 1995 lhs. I thought that my fans were defective until by chance checked the relays which engine was running.

AC blows cold while moving, and gets warmer while I'm stopped


There are two fans behind the radiator. One is suppose to begin running when the AC is turned on. The other is to cool the radiator when it gets too warm. Raise the hood with the engine running and AC "on"and see if at least one fan is running.

Car over heats in short distances


This really sounds like your radiator fan is working. Slow speeds under 20MPH the fan is needed badly. Over 20MPH there is enough ram air to sufficiently cool down the radiator. You should find a fuse for it in the Power Distribution Center under the hood. Check big and small. If the fuses are good and you're convinced the radiator fan isn't coming on, try swaping the rad fan relay with another in the PDC. As far as the "Check engine" lite goes, a transmission fault can turn on the lite. However if your radiator fan is not working that will also turn on the "Check engine" lite.
Good luck with that and let me know if you still have issues.
