Vacuum Bypass Closes Heater Valve


Rated 4.5 out of 5 by 2 reviewers.
Rated 5 out of 5 by Perfect replacement for less the cost This valve is a weak connection on GM vehicles and this valve was a perfect replacement. It has an extra rib at its weakest point to make it stronger than the original. August 16, 2016
Rated 4 out of 5 by Product is working My old control valve began leaking and I had it replaced with a new one from Pep Boys and it is working just fine. Pep Boys installed it for me, Jesus at the Sahara location in Las Vegas. He does excellent work. August 5, 2014
