Ok, I have a Honda Del Sol GSR Turbo. I'm having a problem with it heating up. I've had it boosted for a couple years now and never had any problems with it heating up untill now. This is my second car and doesnt see much drive time. It has a pretty much brand new half size fluidyne with a slim fan hard wired so I always leave it on.

Heres what happens, The car can sit and idle for ever with out heating up. Once I start to drive it as long as I keep the RPMs down it will do just fine for about 30-40 mins of driving. If I push the car hard(boost) then it will overheat pretty damn fast. like 10 mins or so...Heres what I've done so far.

I've changed the fluid to make sure ive got 50/50, Ive checked the system for leaks and tested the cap to see if it holds pressure. It all checks out.

I've changed the thermostat, I've also changed one of the coolant sensors(I think the one the tells the fan to engage, this was before I hard wired my fan). Is there another one that I should try to change??

I've also bleed the system many times making sure all the air was out.

The only thing I really have not done THAT I KNOW OF is change/test the water pump.

Does anyone have any clues as of what I should do next or how I should go about checking to make sure the water pump is working 100% before I rip it all apart and its not that...

Any help is much needed guys im trying to sell this car and its not to easy with this problem.

 

no one has any advice?

 

FLUSH the radiator and check any hoses for leaks (IE cuts tears etc).

 

did you read anything I wrote? I did all that... I know the basic things to look for I just want to know how to check the water pump or if I can?

 

Did YOU read anything you wrote? I said FLUSH the system, not bleed it. Hopefully when you bled the system you put the in-cabin temperature setting to its maximum. You checked for leaks, great. Go back and visually inspect each hose for cuts or tears. If the water pump wasnt working, it would overheat no matter how hard you push it. Make sure your oil level is up to par as well. There isnt really anything left to cover besides a headgasket issue.
