The fan is not designed to run all the time (comes on at 225F), so if the engine is not overheating you have no problem.

SOURCE: Both radiator fans on my 2002 Toyota Solara V6 run constantly

Check to see if the radiator fan relay has gone bad and needs to be replaced. Once you located the relay, (in the fuse box under the hood) Try swapping it out with another relay and see if the fans stop, if the fans stop working with the swapped relay, replace the relay. It's know for the relays when they go bad to stick and will have a close loop. Good luck and hope this helps. Keep me posted, be glad to help you get your car running 100% again soon.

The fans are controlled by the ECM.they will not normally come on untill about 235 degrees.Have someone put a scan tool on your car,run it and see how hot it gets.Your new engine may a different coolant sensor, which changed the reading on your gauge.

SOURCE: cooling fan will only work when the ac is on

Normal unless the engine is over 225 degrees and then the fans should come on.

Have you replaced the temperature switch sensors?
Most Mazdas and cars now days have a temperature sensor and a thermostat sensor that will operate the two fans on different temperatures/settings... Good luck!

I bought my 1999 oldsmobile cutlass new and now im having problems with my motor fans coming on,my ac don't work anymore but for the fans to come on I have to turn my ac switch on,if I switch to heat


If the fans work, (I'm guessing there are two of them) only when the A/C is on, then it means that the temperature sensor is damage. If possible, have a professional take a look at it. Both fans are OK,

Is your ac fan coming on when you turn on the ac? If it only getting hot when you turn ac on I'd say your ac fan isnt coming on so check your ac relay and ac fuses. Is your ac blowing cold

Engine cooling fan only works when ac or defrost is on


if engine at long stand still,the engine temperature will rise about 190 degrees the cooling fan suppose to automaticaly turn on when coolant temperature sensor get hot it cause its resistance decrease causing pcm to send power to coolant fan relays and cooling fans, when you turn on AC the cooling fans suppose to turn on to cool down AC CONDENSOR, IF NOT AC WONT WORK COOLING FAN COOLS DOWN REFRIGERANT SO IT CAN RECYCLE THROUGH THE SYSTEM AGAIN.your cooling is suppose to turn on when engine at a sit still if vechicle not moving as coolant temperature rises at a set point the cooling fans will turn on cool down engine.cooling fans dont turn on when you first cold stsrt vechicle unless you have AC SWITCH ON.if cooling fans dont turn on when vechicle at a long stand still or moving along slow traffic.if coolant temperature sensor been replaced and fuses and relays okay have dealership check see if pcm driver circuit working faulty pcm will cause cooling fans not to turn on.
