First of all I dont have a Civic, but I figured there are probably more people here with a boosted h22 than in the Accord forum and I am in need of some advice. I have a 92 Accord and in the summer on really hot days the engine overheats. I have a Yonaka half rad, and I have checked everything else that could cause the overheating and I believe that the Yonaka rad isen't very good. So a question to those who have a boosted h22, what rad do you have? And do you have any advice? Thanks

 

have you check your water pump?

 

an oil cooler?

 

I replace the water pump about 30K miles ago, so I pretty sure it's not that. The overheating only started after boosting the engine, it just gets so hot under there. And I haven't tried an oil cooler yet

 

check your thermo stat. 2nd check you head gasket.
I bet your head gasket is letting out some exhaust into your cooling system. after you drive it for a bit... is the rad hoses under lots of presure? if you can, put a smog sniffer over the radiator with the cap off, see if there are any hydro carbons in there.

 

The thermostat is fine, and I did a compression test to check the h/g and the #'s were good all across the board. As far as checking the rad hoses and doing the tests with the smog sniffer I will try that, the problem is my car is in storage for the winter and I wont know until spring, I am just getting ready for what I know willl happen once the summer arrives

 

So what rad does everyone with a boosted h22 have?
