Having problems with your 1994 Ford Explorer Limited ?

My 1994 Ford Explorer continiously overheats. I have changed thermostat 2 times, replaced hoses, flushed radiator, replaced fan & fan clutch. Still overheating immediately within minutes of driving. All of these different many solutions Ive tried, none have yet to help resolve the overheating.

I agree with the first response.\012
\012Head gaskets can fail several different ways and yours has failed between the water jacket and a cylinder.\012This allows the hot gases produced during the firing cycle to enter the cooling jacket heating the coolant far more than normal.\012
\012If you DIY or have it done, be sure to have the head checked for warp and milled if out of tolerance otherwise the new gasket won't last very long either.\012If the warp is serious and milling the head would cost too much headroom, the head may have to be scrapped.\012
\012Blocks warp only rarely but it would be wise to check the block as well at the mating surface with the head.
Have you checked out the converter? If it is 16 years old and partially blocked,that would restrict exhaust flow and not help get rid of heat.
\015\012Is the fan running, if not, a bad switch,not bringing it on, often enough.
\015\012Is the thermostat in the correct way, or upside down?
\015\012The water pump impeller may have corroded away, and be spinning,instead of pumping.
