Cooling issues... keeping it coo while, im not keeping my cool

freinds jeep did the same thing it was a bad head gasket. was alright if u were driving it but let it set it would sometimes peg the temp gauge. head gasket finnaly blew out completely after awhile

you wont get oil in your rad or block if it is cracked next to the exhaust port..just use some water and bubble in the rad when it is running...fill the rad or holding tank to the top, if you keep getting bubbles from rad...you have problems!!!!

if you use the pressure tester, put it up to the pressure that it says on the radator cap, and it doesnt hold it very long, you either got a cracked head, a bad gasket, or something, your loosing pressure somewhere. If it holds just fine on a cold engine, warm it up with the cap off the radiator and test it agian, see if it leaks with the engine warm.   

Test the cap too while your at it, make sure it lets the pressure off at the right PSI.    Somewhere in those tests you should find the problem.

Still have not put water in it to figure it out.  But someone might have figured it for me.. They said my clutch driven fan was to loose and it spun to freely.. It almost spins just like the electric fan when its all shut off and you spin it by hand..

Sound right?

i dont know how to test those fans, other than to stick one on thats known to be good, and see if it fixes it.   I have a thermal clutch (whatever they call it) on my s10, when its cold it spins easy too..

i was told that when its just sitting there it should not spin just freely. It should spin but should have a good bit of resistance when you try and spin it.. There is almost none

That is correct...I just checked mine and there is quite a bit of resistance. The clutch is probably shot in yours and that will cause it to over heat when the vehicle is not moving. Does it stay cool when you are driving it down the freeway?

[JaiDeeEmm]

Yes moving it stays cool but leave it sit for 5 minutes and the temp creeps up

Yep replace the fan...this is not the first time I heard of this problem. I have never had one go bad on me but I have heard of other people that have. You don't have to use a clutch type fan either you can replace it with a direct drive if you want just as long as it bolts up to your water pump and clears belts, hoses, shroud, that will probably be a cheaper option.

Or go with an electric fan.

Being that i have a winch i think id be better of with the motor driven one.. Electric fan would probably  eat up to much electricity for my stock alternator at this time..

[RIP_K52007]

maybe mines shot too.. spins pretty freely.. give it a good spin and it goes around 7 or 8 times..  but my 4 cyl hardly ever hits 140 degrees anyways..
