charge cooler pump, do a search dude tooo much info on that

sounds like it could be the intercooler pump. it's a known problem so if yours hasn't ever been changed, it's a good place to start. have a new one put in under warranty or change out to an aftermarket pump like the johnson cm30 yourself for $150 and report back.

Intercooler pump, $150. I have one new in box that I can ship to you for $150 if you like, is a cm30.

thanks guys for info , i will chage that too , one more question ,i am looking to get heat exchanger ,its easy to install?

No offense here, but if you have already shelled out $6000+ for something that should have cost you $150 and an hour of your time to install- I'd recommend that you take it to a shop to get it installed. Both IC pump and heat exchanger are simple installs.
