At wits end 15151515
I have a 1985 mercury capri with a 5.0 5spd
it started over heating and i replace the thermostat and it still over heated so i got a 3 core radiator with 2 12in electric fans removed the fan and shrouds and it still over heated .
so i took the thermostat out and it still over heated replace the water pump still over heated humm now i do a pressure test and i hear air leak in the carb so i take the heads off an find a blown head gasket and while looking i find a small crack in the head close to the intake valve, great im so relieved i found the problem , NOT lol i buy a reman head and the gasket set, now i inspected the other head having it off no leaks so i assume its ok and put it all togeather and take it for a ride, i hav a 160 stat in it too it over heats when, i take the rpms up to the 3 4k mark, i bring it back and releave the pressure and fill it again, aslo taking the stat out to loook and it was open, it was ,when i filled it the first time i let it idle and watched the stat open and could watch the flow in the radiator and it will idle for ever not even starting to over heat , but as soon as i rev the motor it pumps all the fluid out of the radiator and the motor is not hot at all untill it pumps all the fluid out
I hav take off the stat and while filling the radiator watch the fluid come out of the stat inlet to make sure the pump is pumping it the right way also, Im at wits end with this thing and please dont hate cause it is a mercury
any sujestions would be greatly appreciated
