98 Eldorado.

[Bouncer88]

Replaced thermostat, radiator, coolant hoses. Car still over heats on the high way, not sure what this could be.

Any help?

Is the fan coming on ? also N* motor is notorious for head gasket failure, any oil in antifreeze or vice versa?

Welcome to the blown head gasket club!! The same thing just happened to mine. $3,000.00 is what you will have to shell out for the repair.

Mine is going in this Spring! It has only 85,000 miles on it so, it is worth it to me as the rest of the car is flawless!!
