have you done a real good flush of the cooling system? my cadillac wasn't taken care of fer ****, and it needed mutiple flushes of EVERY fluid except the rear. The heat core was clogged, and the coolant was brown. I'm whilling to bet the radiator is pluged, or the fans have burnt out/switch burnt out. Flush it at a low PSI for awhile. keep pting the garden hose in different hose combos for the best flush. then run it till it gets warm, and do it again.

not sure about the smoke.

Are you using the same fuel that was in it before it was put away? Was the tank dry when it was put away?

Default Pull the themostat and see if it stays cooler

It may not be in there anyway, then go get a fresh tstat at the same time ....

intake gaskets would have nothing to do with coolant leak. Blue smoke could be a faulty intake gasket, or bad valve stem seals..

but if the intake manifold has coolant passages through it iit could be letting air into the coolant system through the coolant passages and that coul be why the coolant is presurized and shooting out of the resevior tank also if you say the car will smoke blue is the blue smoke from fuel burning because the smoke comeing out smells like like its running to rich which al this leads me to thinking it may be the intake manifold gasket leaking please let me know what you think thanks

no we have a dry intake manifold, NO coolant passes through it. Blue smoke = oil, black smoke = rich/fuel, white = coolant

the car has a single pipe exhaust on it the muffler splits it up to the tips. but if it was sitting up for so long the rad. could of had tap watter in it thus rusting th passage up which could not be cured by a flush you need some on with a infered red heat gun to check the rad. or take it to a rad shop and have it flow tested

you said fans don't come on, it could be that the switch in the PCm burned out, or the fans burned out. Wire up a manual switch, or a temp ativated switch and see what happens.

Just bought it.... and you wanna sell? what gives?
