I have a 1989 trooperII 2.8 litter V6 4x4 I can't get it to stop over heating. My oil is not milky and no water is comeing out og the tail pipe and there are no leaks... ? Also it runs ruff like it's out of timeing but I'm not sure? and the check eng. light is on and the dealer wants 100.00 to just tell me why it's on wow high much. So if anyone can help me with this or any of these things please please please do so my e-mail is k_e_y_e_s yahoo com thank you all.I have lots of new parts under the hood like a radiator and a thermostat I did not replace the water pump because it is still pushing the water thought the motor and yes autoZone says it's to old me them to run the check eng. light test. so.....oh yes it has around 170,000miles oh it. ouch but it still runs strong!!! :banghead: :banghead: :banghead: :banghead:

Autozone will read the codes for free. Or you can buy a code reader for under 50 bucks.

How many miles do you have on it? Is the Radiator orginal?

ever replace the thermostat, water pump?

I think I've been to Autozone for codes on my 93. I was told it was too old, so since his is an 89 this may not be a good option.

Ok good news everybody found out what was wrong with the overheating Autozone sold me the wrong part they gave me a right handed fan that turn clock wise now I don't know about other troopers but my 89' turns counter clock wise there for I needed a left handed fan that fixed everything now if I can only find out about that check eng. light ? thanks guys for the help.

There should be a way for you to read the light yourself at home. I am not sure of the procedure to do it, hopefully someone else does know. If not, ask over on 4x4wire.com.
