Question about 1997 Pontiac Bonneville

1 Answer

I need help please. Have had car worked on and something is missing right over fans by radiator. Does a 1997 Pontiac Bonneville 6cyl 3.8 have a fan shroud Assembly? The car is missing something and engine is not overheating but pushing hot air into inside car and fogging windshield. Also, you can put your hand by engine fan and it is blowing straight up and that never happened before. Please, Any suggestions? Thank you, Renee

97 pontiac bonneville. The cooling fans are not working and the engine temperature climbs when stopped. Also, the coolant gauge is coming on as low but it is full.


if your fans are electric check fuses and relay if they are good replace your coolant temp sensor that is what is most likely wrong anyway cheap at auto zone they are normally located right by thermostat housing or in the side of the block it tells your cars ecu when to cut on fans.

if your fan is belt driven replace you fan clutch and problem solved


if this helps you could you leave me good feedback thanks

Have a 92 Pontiac Bonneville SE, runs "warm" (over 210). Once the engine fan kicks on, it never shuts off. I've replaced the entire fan assembly but new fan started doing the same thing. Is there another...


good possibility your radiator is partially obstructed either internally (calcification blocking core tubes) or externally (leaves etc either in front of a/c condenser or between condenser and radiator). When that happens,(internal) heat transfer is lessened and the fan will work overtime to keep the temperature down. Flushing will sometimes help, but chems used are milder than they used to be and often will go around internal obstructions instead of dissolving them.

My 1997 pontiac boneville SSEI cooling fans never come on


Hey i have a 96 Bonneville SE :) I had the same problem....., First off .

Unplug you're fans.. Take some wires, ( i used speaker wire. ) Have someone help you, :) connect it to you're fan and then to the battery one to ground one to power. If you're fan doesn't turn on then you're motor in the fan is dead.

2nd. Check you're relays, Easy way to do this is switch them around one by one... They can't all be bad :P and if it turns on.. then you have a bad relay:P

3rd. Does you're Temp gauge work? There are a few sensors That could need to be replaced.

Cooling system leakage/temperature fluctuation


Hi, the fan in the cooling sistem plays a very important role ,if the fan dont work properly that kind of temperature variations may happens,this can be coused by a bad temperature suitch, a bad relay or defective fan ,,another posibility is a bad thermostate ,even if is new it can be defective, water pump should also be checked......(never heard of any seals.) GOOD LUCK..
