Running Hot

I have an 88 samurai with a 1.6. Lately when I let it sit for about 10 minutes (Usually when I'm stuck and have to winch out), The engine temp rapidly rises even with the heat on. Any ideas on how to keep it cool? It's only been about 60 degrees and I am worried in the summer when it is hot i am going to have problems with it boiling over. Better fan? High performance coolant? Any ideas?

Re: Running Hot

My '89 sidekick 1.6L performs similarly....I've been told to check the fan clutch (with warmed-up engine off, check if it spins freely, if so, needs replacement), water pump, and coolant level. I've put a lower temp thermostat (160 deg I think) in mine and it keeps any temp rise in check and not critical. keeping the engine revving slightly also keeps the temp down (I assume b/c the water is cycling quicker). hope this helps.

Re: Running Hot

Besides all the resposnses so far if you have even a small head gasket leak engine will overheat.
Exhaust gas test at radiator cap will confirm. A larger engine with the same old radiator is
always a little marginal. To see if the radiator is doing its job check inlet and outlet temp of radiator.
Can also check fan clutch slippage with timing light.
