It would be the third from the front on the driver's side for the V-8. On the six cylinder it would be the fifth from the front.

Hope this helps,

Bob

Ok, part two. Why would it overheat for no particular reason? Coolant level is good. Changed thermostat. Sometimes it just does it. No apparent loss of coolant.

Well, it won't over heat for no reason. It's just a matter of finding out why. Things like timing are alway a possibility, but that usually comes with a nest of other problems that has you timing conscious before the overheating.

Over heating is usually very basic:

A clogged radiator/condenser which inhibits air flow.
A loose belt on the water pump.
A bad fan clutch.
A clogged coolant flow either in the radiator or else in the engine. It much more likely to be in the radiator itself since it sort of strains everything out as the coolant passes.
A bad thermostat, which you've changed.
A collapsed intake hose going to the water pump. Normally these are spring supported, but they can still go bad.
Also, oddly enough, a too heavy a concentration of antifreeze will cause overheating. It's too thick to pass freely through the radiator core.

On the less frequent order, a leaking head gasket.

There may be a few more, but these are the ones that I usually suspect.

Hope this helps,

Bob
