i have been having overheating problem in my 88 accord. i have replaced thermostat, temp fan switch, tested relay switch works fine, put in new radiator, both fans work, no broken fins, replaced water pump, all hoses, the bypass hoses,all new parts. cleaned and inspected the metal pipe that is under the intake manifold, and flushed the engine out with clean water. i have wired the fans to run all the time to keep the engine cool but it still gets really hot on hot days and also gets really hot at freeway speeds, even with the fans running continuously. The next thing i will try is getting a aftermarket high cfm fan to help cool. this cooling problem has already cost me one engine. Any suggestions would be appreciated.

 

Is the radiator plugged up? A new radiator would cost much less than a new engine

 

do a leakage test , to make sure you don't have a blown head gasket

 

I know u said u put in a raditor but if u got it at a junkyard or if its used then check underneath the hose at top they like to crack right there on accords

 

as stated in my description of what i all i replaced all the parts i replaced were all brand new from the parts store.
