Mercury Sable: My 96 Sable is over heating fairly quickly.

This answer was rated:

My 96 Sable is over heating fairly quickly. The coolant reservoir is full and there are no apparent leaks from the radiator or hoses. Could this be a pump issue or a problem with the thermostat?

hi,my name is XXXXX XXXXX I will help you..the thermostat,most likely is not the issue here .

these years had issues with cracked heads and or gaskets and a block test should be done ..if it overheats in say 7-10 minutes then moost likely the heads are cracked .

the block test consists of a tube filled with a blue lt yellow if the presense of hydro carbons is present in the cooling system.

a lot of times it may not show white smoke out of the tail pipe .

the tube is placed over the fill resivior a(warmed motor ) and the bulb on it is squeezed to draw in fumes ,if the color turns then the heads need to be takken of and sent to a machine shop for further checking ..

the system (cooling) my also be low and causing the very quick over heating as well but before a block test should be filled up to par ...jazzmaster ...

Say it is a bad head or bad gasket. How much would you estimate the repair cost to be? Thank you for your time.

you could be looking at over $1200 if the heads are cracked ,which most likely there are or need work to them ...jazzmaster
