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.
if im out looking at the engine is it on the right side...just the left fan one came on when i unpluged the temp sensor on the housing were the thermostat is..well the right fan come on if i unplug the right side temp by the trany
No, the other sensor is just for the gauge, the other fan only operates with the ac, the fan turned on which means the cooling fan circuit is good, the other fan is for the ac system, to test that one start engine and turn ac on, fan should turn on if ac is working but for now we need to get the fan for the coolant to work and this fan is working so the next test is the block test to see if exhaust is entering the cooling system, then we can go from there, good day.
