Re: how to change a thermostat (pliskin8)
there is the thermostat housing on the backside of the motor. (follow the bottom radiator hose to it).. There are 2 10mm bolts to unbolt and then the front part will come off the housing, just take the old one out and put the new one in..

Wait. Bad thermostats won't cause overheating. When a thermostat goes bad, I believe it stays OPEN, as in the car would actually take longer to warm up to operating temp. Of course I might be wrong but thats what I've always heard and read. Good luck!

They can also stay close, which will result in over-heating

Yes... happened to me two or three summers ago. Car was overheating, pulled the t-stat to test and it didn't even start to open until (if I remember correctly) something like 40 deg over what was called for in the service manual.
I actually put in three different t-stats before I corrected the problem. 2 from the auto parts stores that didn't work in the car, even though they tested at the right temp. The third was OEM from the dealer; worked like a charm.

we thought it was te thermostat 'cause the radiator had no leaks the fan was working just fine so it had to be the t-stat

keep this in mind though:
there is a 97% chance that your buddy has a blown or blowing headgasket.
there was a service bulletin on the pre 95 headgaskets. honda used a metal impregnated paper gasket instead of the 95+ metal gasket.
damn near guaranteed to fail.
it will start with occasional overheating and a mild amount of coolant consumption.
eventually it will just blow all together.
don't bother to fix it till it happens, but be aware of it.
