can be lots of things,,,
overheated engine, warped head, and now head gasket blown.
or cracked block.
or cracked heads.
we find this doing tests. want to test or gue$$.
do a compression test or the cylinder leak down test.
on DOHC we do the latter, by hand.

whether you are a 2WD or 4WD the gap is 0.040

Hey there Alex,
I am going to say no...
I did check the interchange and Hollander Interchange says no.
Reason being , the carriers are different.
I am assuming you are working on a 2wd , or you would have mentioned the front axle assembly as well.

when they replace the clutch fan still overheating? if yes, that means he is not a mechanic or he just want to make money, but if no, then they replace it and about the electric fan no electric fan and the clutch fan together

it sounds like you need a new Radiator or you are leaking coolant and thats why its overheating, check your rad fins and then your coolant level

Cap pressure is best determined by going to the auto parts store and buying a new one. You can ask the counter guys to look it up online before actually buying.
Most radiators today run 15 PSI, but the cap is just a safety valve, and has nothing to do with controlling the actual pressure. The thermostat does that, and if your having boil over problems, then you need to be looking to other causes (plugged radiator, bad water pump, etc.).

The firing order for a six cylinder is 1-2-3-4-5-6 distributor rotation-clockwise...cylinders 1-3-5 on drivers side...2-4-6 on passenger side
