Check the fan relay by following fan motor wires to relay and pull relay and check resistance whit a multi-tester or ohmmeter. Make sure it will get current. If the relay is good, the fan motor may be bad.

Also make sure you are using a 50/50 coolant mix. This is the exact mixture any car should have.
Also 5w30 oil in summer time or use sythetic which adjust to any temperature.
Can always replace your thermostat if you feel like it.

SOURCE: My 97 dodge intrepid 3.5L is running hot.

Check the connection betwteen the temp sensor, located on the block and check your fuses/relays. It may help if you pull and reseat each fuse. This is free and saves a lot of headache swapping out parts.

SOURCE: engine cooling fan not coming on

It may be the fan itself. Try to find the plug going to the fan, it should be close to the fan and might plug diresctly into the relay. Use two jumper wires straight from the Bat one from the pos+ side and one from the neg- side and plug them into the two holes in the connector the fan should start WATCH YOUR FINGERS. If it starts its elec prob before the fan if not its the fan.

Car is running hot and I put a new thermostat in and water bump


make sure the radiator cooling fans are coming on. GM has also had major problems with the lower intake gaskets leaking on the V-6 engines. sometimes when refilling the cooling systems air lock can occur. run the engine until it warms up and then turn off and let it cool down, if coolant level goes down repeat this process two or three times. other causes could be clogged radiator, or worse case scenario blown head gaskets. also i have on occasion got bad thermostats from the parts store. the upper radiator hose will get very hot when the thermostat opens. run the engine and hold the upper hose and when the t-stat opens the hose will get hot. then when the cooling fan comes on hot air will rush from from the fans. if the fans come on and the air is cool then there is a circulation problem. t-stat, clogged radiator, low coolant, head gaskets. good luck.

I have a 98 sunfire. should the cooling fan on the radiator come on from the initial start up?


The engine cooling fan is designed to come on when the engine reaches 225-235 degrees Fahrenheit. That is the only time it runs. Do you get a check engine light?

Engine runs hot after a few minutes of running the car


That is very vague. Have you checked the radiator, and when it is hot does the electric cooling fan come on? Try running the A/C and see if the cooling fan comes on. Does it run hot on the highway or just in city traffic? I need some more details to try and narrow it down. There are many things it could be. Low coolant, stuck thermostat, air in the cooling system, bad fan motor, fan motor relay (also known as fan switch), or temp sensor.

Cooling fan won't come when engine is hot


Check the thermostat to see if that is the reason the engine is running hot. Sometimes if the thermostat is bad the sensors for the engine fan won't trigger the fan to come on.

93 villager runs good, but temp. gauge runs up to the hot line, but never runs hot. is the a colling fan that should go on.


the cooling fan should come on low speed and then high speed as it gets hotter.

The fan should come on anytime the a/c clutch engages, even cold engine.

1995 cutlass supreme. There are two cooling fans.


it will come on but only when the engine is very hot and the first fan cant cool it down that fast,, its turned on by a difrent heat censor so the engine needs to be realy hot to set the second fan running and it may even then only run for 30 seconds till the engine temp drops off,,, as long as the car is running in the normal heat range dont worry about it,,, if its cooking way up in the red,,,,,now worry about it,,fast too,,
