Cooling fan start right away - 1995 Mitsubishi Mighty Max

Taken from other previous solution (but it's right): the cooling fans are switched off and on by a relay. either this relay bad and staying on all the time, or something else is bad and telling it to stay on all the time. you might unplug the engine coolant temp sensor and see if the fans switch off. if they do you have a bad temp sensor, if they don't you probably have a bad relay. they will test either for you at most car parts stores. the relay will be in the underhood power distribution box, it plugs in like a fuse. disconnect the battery negative terminal before you start unplugging things from the power distribution box. hope that helps

check cooling fan fuse, a quick way to check, turn on your A/C while the car is running, the cooling fans should come on right away, if not try a direct wire from the battery to the fan plug, that will tell you if you fan motor or motor's are bad.

Check the cooling fans. They likely aren't working. These vehicles are common for have a bad cooling fan relay.

If relay and fan fuse are good, disconnect coolant temp. sensor, sensor will be on thermostat housing or just below it, fan should come on right away, if it does replace sensor, if it don't check voltage at cooling fan harness with sensor disconnected, if you have voltage there replace cooling fan assembly.

most likey the temperature sensor on the cylinder head somewhere

You need to determine why the fan is on (stuck relay, bad sensor etc.) If it remains on, the computer keeps engine controls in "cold-start" mode and will not operate properly. (re-check codes after the fan works right.)

The fan runs on a thermostatic switch that will not start the fan until it gets above operating temperature. This thermostatic switch needs replaced.

make sure the cooling fans are working and most vehicles will turn on the fans when you first start and A/c is in max mode
