Question about 1995 Chevrolet Lumina
Posted by Anonymous on
It sounds like the cooling fans may be seized and need replacing.there is a fan relay in the relay box under the hood,but they don`t go bad too often.if you run jumper wires to were the fan plug connects(one power and one ground) the fans should work.if not then the fans need replacing.

No,it sounds like you have taken the correct steps here.these 3.1 engines run a little hot, the fans will not come on until the temp reachs over three quater the way on the gauge, they are also prone to a bad temp sender, this is located on the rear head near the trany, but if its overheating and you have bleed the system then theres a problem, when i say overheating i mean the gauge goes to hot and coolant boils over and out the resivior, if this is the case then the next thing would be to have a block test done, these engine are also known for headgasket problems, this is when exhaust enters the cooling system and stops the flow causing it to overheat, a quick test to see if the fans are operating correctly and the relay also is to start the engine and then disconnect the coolant temp sensor and fans should run, if the fans turn on then have the test done, this test is done by draining coolant down a little then theres a tube that holds the fluid that sits on radiator where the cap is and if exhaust is entering then the fluid will turn yellow and this means a head or gasket problem.good day.
