I'm doing a knock sensor swap on my 2001 Silverado with the 5.3. I noticed a leak, which is more than like the water pump but I cant tell if it is or isn't. The truck has the coolant crossover steam pipes that go to all four corners. I'd like to go ahead and swap it out for the newer O ring style that plugs the rears and goes between the two fronts. I see the car style all over but cant find the truck style anywhere. Do you guys have a part number or a link to where I can find those? I'd appreciate your info if you don't mind lending it! ----Jeremy

Welcome to LS1tech! It's about time you posted something!

Why do you want to reduce the cooling to the rear corners? I'd leave the rear tube in use.
