Question about 1993 Cadillac Eldorado
I changed head gaskets, remachined heads, replaced water pump but but by-passed thermostat, engine still over heats, my fans are working dont know what else to do
I am assuming you have the Northstar engine.
Check for coolant flow at the Purge line,this is a common problem on the Northstar.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.
Are you running it without a thermostat? If so,then strangely enough,this will cause overheating as the Northstar cooling system is different to most conventional systems and therefore will not help you diagnose the problem.
