Engine cooling fan not running checked fuse ok

You won't know which until you check. Unlikely the wires. Fuse or sencer most likely. Check the large fuses first. If it is the fuse then check the wires as somthing the matter with them or the fan itself. Turn the fan with your hand (with engine turned off.) it should turn freely. If all this is ok then you need a senser.

Check to see if the fans are connected to the wiring harness, if radiator was removed the shroud and fans had to be removed, are fan motors connected to wiring harness, are there any damaged wires at connectors, check the fans fuses at fuse box (Power Distribution Box) in the engine compartment (front right side)(push in on tab in front of box lift up then back to remove cover), Engine Cooling Fan Fuse, Yellow 60 amp, posistion #49, Check the Relays, Engine High Speed Cooling Fan, posistion #R8, Engine Cooling Fan, posistion #R9.

if you think it may be the cooling fans. then check the fan relay and fuse in fuse box. if they are ok! then run a wire from positive on battery to positive on fan connection, run another wire from neagative on battery to other connection on fan. if the fans are good,they will turn on. have a good day !! also be sure coolant is at proper level.

cooling fan will not come on until about 230 degrees, if fans still do not work. check the fuses and relay. if ok then run a wire to fan from battery.on fan side connection, run a wire from battery positive to fan connection. run a wire from negative to ground connection.if fan will not come on it is either bad or the coolant temp, sensor is bad. because this sensor send info to pcm from various running conditions. it is very important that this sensor works. it can cause;

Extended crank time when the engine is cold

Poor fuel economy

Spark knock

Lack of engine power

Erratic and/or high idle

Engine cooling fan stays running all the time

Engine cooling fan fails to turn on

Engine overheating

FIRST IS CHECK ENGINE LIGHT ON....YOU SHOULD BE ABLE TO UNPLUG THE ECT... ELECTRONIC COOLING TEMP SENSOR.....A TWO WIRE SENSOR THAT TELLS THE COMPUTER THE TEMP OF MOTOR....WHEN THE MOTOR TEMP GETS HIGH THE COMPUTER GROUNDS THE COOLING FAN RELAY TO TURN FANS ON..IF FANS DON'T RUN WITH SENSOR UNPLUGGED THE GET A SMALL PIECE OF WIRE AND FOR A SHORT TIME SHORT THE TWO WIRES ON THE PLUG FOR SENSOR...IF IT DOES COME ON REPLACE SENSOR IF IT DOES NOT COME ON SUSPECT COMPUTER...ONLY IF ALL FUSES ARE OK LET ME KNOW

The fan will only come on when the water temp. reaches about 80 digrees with the new water pump the temp. is staying low and the fan is not needed. Drive it a while checking the temp. guage if it over heats and the fan doesnt com on then you have a problem if not all is o.k.

test

Here are the cooling system diagnostic steps...First does the cooling fan kick on (with engine hot)? If not, check the fuse, if good then check the thermoswitch in the radiator (it's about an inch and a half in diameter located on the lower part of the radiator with two wires ) by disconnecting the wires and touching them together (again, with engine hot...at least 190 degrees) if the fan comes on, you have a bad switch. If not connect a 10 gauge jumper wire from the battery to the fan itself (there are three terminals,,, one high, one low and ground). With power direct from the battery (and a ground wire, if necessary) fan should run... if not replace the fan assembly... if it does run then you have a bad cooling fan relay. It will be located above the fuses on the fuse block... Hope this helps...;-)
