Replacing the relay would be the cheapest thing to do first. Before you replace it be sure that the connection, where the relay goes, is good. You may also want to add some gel that keeps contacts clean. The gel can also be found at the local autoparts store. Good Luck.

Did you check the cooling fan relay's ? Your vehicle has three of them . Free wiring diagrams at http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model an engine size . Under system click on engine , then under subsystem click on cooling fans . Then click the search button then the blue link . Learning how the fans work then testing the electrical circuits is how we as Technician solve problems like this . We don't ask if anyone has this issue an knows how to solve it . Someone else's fix maybe different from what it will take to fix yours .
The cooling fan's are computer controlled ,by the PCM - powertrain control module . When the engine coolant temp. gets hot enough the PCM see's this through the use of a coolant temp. sensor . When it reaches 212 degress the PCM energizes relay # 1 sending B+ voltage through both cooling fans to ground causing low speed .

Engine over heats


Check for collapsed radiator hose first.

Do the cooling fans come on? If not, check fuse, relay and if still no function- fan thermostat switch.

If fans do come on, replace water pump.

Radiator fan on drivers side will not engage motor overheats. what can be the cause?


There are a few. I have see the ground rust off, the fan motors burnt out, the fuse relay box. The best way to check is using a test light connect it to the two wires of the fan run the engine. If the light comes on before it starts to overheat then check the fan. If not the check the relay. But before you look at the fan make sure the fuse is good.

Electric cooling fan


check wiring to fan for 12 volts. check wiring and see if there is a relay that can be replaced or tested. If the relay is good, and wiring has 12 volts, then either the temp sensor or fan motor brushes are shot.

The brown muddy color is usually caused by not using coolant. Have you been just putting in water, or very weak antifreeze.

There are a lot of things that can cause the overheating when under a load.

1) Clutch fan could be weak. Check to see if there is play front to back, move it up and down and see if there is allot of resistance, no resistance or little resistance. You want the latter.

2) Water pump veins may be worn down or off not circulating the antifreeze.

3) you radiator cap may not be holding pressure.

4) There may be a restriction on air flow. If you have A/C the condenser may be blocking the air flow through the radiator.

Hope this helps.

No its not true,the cooling fan comes on when the coolant temp reaches a certain point it closes the switch in the temp sensor wich in turn closes the relay and powers the cooling fan,the reason it comes on with the A/C is that it's wired to bypass the temp sensor and associated relay because the A/C compressor forces the motor to work harder and the coolant temp to rise significantly faster,the relay needs to be replaced or you will overheat the motor and possibly cause serious damage.
