Ok Ive got a 95 and have replaced computer, radiator, 180 therm., new coolant sensor upper and lower intake. now all the sudden it wants to over heat, I turned on the a/c and no fans, temp got up to 240 and I unpluged the coolant sensor and they came on, now my ? is why arnt they coming on at 200 like there supposed to. Do I have another bad computer? Please help!!!!

Sounds like you have air in the cooling system. Check that first.

Where are you getting that they are suppose to come on at 200?

How would air get in the system? It ran fine for months, and just today it started to overheat. I havent popped the rad cap in months. I checked the fuses and relays they look good, Dont understand why they wont come on when it gets to temp.

Sorry Mike 220.

It'* possible you may be eating coolant. Pull your TB hose off along with the MAF screen and look past your throttle plate. Check for coolant pooling up in the plenum.

Damn I hope not, just did Uim and lim last year. My coolant res. dosent seem low.

It'* usually the EGR stove pipe that causes the damage first. Lot'* of heat and plastic UIM'* don't mix well.

I know the computers tend to fail easily and I had trouble with the last one not fireing an injector few moths ago, think it might have something to do with it? Ill check the uim in the morning.

What? Not turning the fans on? Dunno. I'm looking it up in the FSM right now. But first, we need to find out why your engine is getting so darn hot. How'* the fluid level in the radiator?
