Hey guys I'v owned 2002 chevy camaro Z28 for over 5years now however I'v always liked the look of the G35 coupe so 2 weeks ago I purchased a 2004 coupe (desert platinum) A/T 33K miles. I decided to install a plenum spacer 5/16 with a coolant by-pass valve. Everything was going fine untill yesterday my car began to overheat, Could this be due to the by-pass valve? what do you guys think?

Thanks

 

No... unless you cut the wrong hose, maybe. I did this mod months ago, and there are a ton of people who have done this without the overheating...

Any Chance yo can get a pic to show us which hose you cut/spliced?

And... welcome to Driver !!!
