That's odd, usually there is a label inside the box cover. usally the temp sensor is up either on or very near the thermostat housing at the front of the head. Some also have a second sensor on the left rear of the head. (not sure which one feeds the control unit that turns on the relay)

Usually the electric fan(s) are temperature activated. I would look into the temp switch. If you're not sure what it is, go to the auto parts place and ask for one. This way you can look at it then hunt for it under the hood. It usually screws into the engine in the cooling system. Also, make sure the fan has a good ground. Check for power to the fan when the engine warms up. If you have a/c, turn it on and the fan should come on whether the engine is warm or not.

Hope this helps. Good Luck

How do i set the timing on a 2002 jeep grand cherokee laredo 6 cyl?


Your timing is locked. (distributor is installed with no adjustment feature... on 02's you may not even have a distributor as it's replaced by the cam sensor) All timing and fuel mixture is controlled by the engine computer. Main inputs to the computer that influence changes are the throttle position sensor and MAP sensor but all sensor inputs are evaluated.

97 Jeep grand cherokee 6 cyl. idles down to 0 and dies.


any leaks in intake or exhaust upstream of the sensors, sparkplug condition and engine controls/sensors for out of range operation (including fuel pressure and condition of regulator)
IAC should be cleaned and checked as this can cause poor idle and shut down. I'm not saying not to change O2 sensors, but unless everything else if OK, it probably won't help.

How easy is it to replace the radiator a 02 jeep grand cher. 6 cy


I have tons of experience...for me, its about a 2. If you have little experience, about a 6 (on scale of 1-10) if you get a manual to give you some guidance, it should not be a terrible job, but may take a while. Always use flair nut wrenches on trans line fittings, Check fasteners before you start...some may be torks head and lots of people don't have them on hand (available wherever tools are sold)
Take care not to damage core of unit when removing or replacing.
Any technical questions along the way, just ask!!!

02 jeep grand Cherokee 6 cyl seems to idle too high. When stopping ,vehicle wants to keep pulling forward and have to apply brakes harder to stop vehicle. Very troublesome in snowy conditions.


check for vacum leaks using a spray bottle of water  when the idle frops you found it  if water wont work try starting fluid or carb cleaner  if useing these the idle may increase  when you find it  replace/repair the hose and see if its still happending  could also be a combination of things  idle speed control motor idle air control motor  mass air flow sensor  good luck
