Mysterious leak/ Overheating

ghost88 · 12-04-2008, 01:22 AM

i know that head gaskets are a common problem for supras because of factory torque settings being to low and head gaskets being cheap or old.

replace anything old - water pump/thermostat/head gaskets then try
again. if problem persists i read on another forum that the block may have to be checked. look for discolored oil and bubbles in the antifreeze. also make sure the fan shroud is still on.

anyway, hope this helps some, its the best i know. my supra overheated several years ago, i had no idea why, it was out of the blue, gaskets had went. i replaced them with steel reinforced gaskets and increased the torque settings.
