So here's the question and yes I have a searched to forum I haven't found any straight answers just curious if anyone has encountered this problem before.....so about a month back I replaced my thermostat, thermostat housing, water pump, flushed the radiator and the heater core, and replaced the radiator cap....with that being said I went for a little light off-roading last weekend and it over heated! But when I drive it back and forth to work it never gets over 180° the radiator is the last thing to.be replaced I'm not sure if its the original or if its been replaced any help will be much appreciated thanx in advanced!

 

I can almost guarantee you that its either the fan clutch, or the electric fan was not coming on.

 

Its got to be the fans.

 

I was also think that the fan clutch seems to work and the electric fan come to think of I've never heard it come on? Which would make sense...does the electric fan have anything to do with the a/c or just the radiator?

 

Check your fan(s) at low speeds I.E. offroading not enough air gets pulled trhough the radiator I have an aux elec fan that rarely gets turned (Via switch) on except extreme heat and or low speed.

 

Should just be radiator you can always hard wire a manual switch to the elec fan so you can control when it comes on and off.
If you do that though I would through in a relay.

 

Relay being a type of a fuse? Sorry got all the questions I paint cars mechanical ehhhh not.my strong suite lol

 

For*

 

The first picture is of a 4 pin fuse what you would want to use in this situation.

The second is how you would wire it up.

 

Ohh sweet man really appreciate the help should I check that the fan even works first by supplying power to it to make sure the.motor in the fan works....and if so will Napa have a relay like that? If nit them any other ideas?

 

Yes you should definately check the fan first run power to it then run a ground real quick to check functionality. And any autoparts store "should" carry the relay and A switch.

 

So I just took a test light to where the relay is for the fan under the hood in the fuse box I hooked up my test.light to the battery ground and stuck the test light in the 87 spot of the diagram you sent me and the test light lit up....also I supplied power to fan to make sure the.motor worked and it did so could the rrelay in the fuse box just very bad?

 

Bad*

 

That is possible you elec fan should run off of a temp sensor if that is out the fan wont turn on as well
I dont know if your does or not. but that could be the problem

 

True is there a way to test my relay if I'm holding it my hand I have booster packs here to test with a 12v source
