My engine keeps wanting to overheat, or at least temps reading hot (between half and three quarters up gauge)
Seems to mostly happen after traveling at higher speeds.
Recently (several months ago) had to replace radiator due to low coolant and overheating.
A friend of mine checked it after initial overheat, but did not pressure test, said "it is fine, you were just low on antifreeze" then it overheated again three days later on the highway, this time shooting antifreeze out the front of radiator.
Old radiator busted, so has new one put in.
Since radiator has been replaced, still having consistent issues with car wanting to overheat.
It seams to only happen after I have the rpm over 3000 for a few or several minutes, then when I slow down, the temperature gauge starts creeping up. Usually turning on the heat will help it from going all the way up, but it keeps fluctuating up, then down, up, then down.
In trying to figure out what is causing this issue,
I have replaced:
Radiator (CARQUEST radiator.
Part No 431480 @ Advance Auto.
Radiator cap(one that came with radiator busted somehow).
Overflow housing (got a hole in it and was spewing after pressure built up in system, this was after pressure test showed no issues)
Timing belt (maintenance).
Water pump (maintenance, but also cold air blowing at idle when heat was on).
Head gasket (because nothing else worked).
Repaired warped head (machined because it had gotten warped due to overheating).
Any ideas what could be the fix? Being as I just dropped $1,000.00 into it, was hoping to keep her for another year or so.
have the same problem?
