🔧 Optimized GM Genuine Parts PCV Hose - 15123628 for Superior Engine Performance Review

This was perfect for my 2006 Colorado. I don't know why this is in the Revain install guide, but it's perfect for the line going from the intake to the valve cover for positive crankcase air pressure. Opposite the PCV valve.

I was cleaning the throttle body on my Colorado and found that oil was leaking from the resonance box onto the engine. I tested this hose and after 7 years it broke and had to be replaced. I purchased this product and it was a direct replacement and I had no problem fitting the product. Colorado 2007 3.7L

I originally saw Lean on Bank 1, then it switched to Low RPM at idle. When one of the errors is reported, the problem is usually related to that area. It will be a combination of joint cracking and mandatory air chamber cleaning. I flushed the airboxes and dried them in an oven at 250 to remove all moisture before reinstalling this new hose. After installing pcv, the ECU error was automatically reset.

My 2004 Colorado 5 cylinder engine had a lean vacuum leak code (PO171) that came up intermittently, but usually showed up at long idle, after which the RPM would drop. Long term fuel trim values were between -15 and -20% and short term around 0. It was found that the PCV hose under the intake manifold was cracked and brittle causing a vacuum leak. A month later, the light of money has not changed. come back for me For $10 it was an easy and quick decision.

Thank you for suggesting this here on Revain! I went to every auto parts store in the area and everyone told me to go to the dealer to get this part and have it installed. The local lobster shop wanted to charge me $500 for it. I was able to buy this whistle here and install it myself. Of course I had to watch a few videos to teach myself how to do it, but I was able to do it myself. I'm a 45 year old female who knows nothing about working with cars but I know I only replaced this part because…
