I dont know for sure what is going on, but the other day and recently my truck almost overheats. I did notice i was low on coolant but not too bad, but last weekend when i was out wheelin my fan shroud fell off onto the fan and it stopped the fan..i have talked to a couple people and they said that clutch fans aren't supposed to just stop like that. Is it possible that my clutch fan is going out?

JMHO, but I think it would stop if the shroud jammed it. It's also possible that you're having temp problems because of the missing/damaged shroud. On many vehicles they're not just there to protect your fingers but are needed for proper cooling. Of course the fan may have been damaged as well and I'd be checking the rad for possible damage too.

Not sure if its hot or cold where you from but this is what i would do if its not freezing ass cold in your parts.


For the time being, I would remove your thermostat until you fix your fan and fan cover. That way you can pretty much 100% guarantee as long as you have the coolant filled you aint gunna have a temp problem.

!! But your heater wont get as hot i believe. !!

Of course this is only temporary so no harm is done to the engine before you get your fan and shroud fixed

If you go the route 80 pickup says and remove your thermostat it will over heat for sure. Your water pump will move the water so fast through the radiator that it won't have time to cool. A better way is to remove the thermostat and cut the center of it out and leave the flange of the thermostat in the housing and put it back together. I tried the thermostat removal and it would not keep cool. You will need the thermostat flange to hold your gasket.

never heard of it getting to hot by removing it.

Well, if you wanna play it really safe, then get a really low temp thermostat and put it in.

a clutch fan is only 41 bucks but i was hoping to not have to drop any more money into the truck for a while seeing as how im about to buy a 1990 supra to use as my daily driver. But i guess im gonna have to although the only time it gets hot is when its sitting still or off roading which is really annoying. so we will see. How big of an influence is the fan shroud on the cooling temp? I have heard it matters and i have heard that it doesn't.

bad85toy......."I was hoping to not have to drop any more money into the truck for a while (quote).

Take the t-stat out, put it in a pot of water on the stove and heat it up. It should open before the water comes to a hard boil. The temp it opens at should be stamped on it. Most are 160,180,or 195 degrees. With the truck warmed up, turn the truck off. The whole radiator should be warm..no cold spots. If you have cold spots, the radiator is probably plugged.

P.S. Wash the pot real Good!!!!!!!
