kissmyss Posted January 4, 2015 Report Posted January 4, 2015 My alternator tensioner started getting weak, so I replaced it with one I purchased from ZZP. When I purchased the tensioner, I also purchased the coolant elbows from ZZP. I went on a road trip, when I returned I noticed coolant leaking on the ground and the leak was coming from the elbows. I didn't think I would have to change the O rings these before installation, I thought it only applied to the Doorman elbows. Luckily no damage occurred from the lack of coolant. I upgraded to the Doorman aluminum elbows and yes I replaced the O rings before installation. ZZP elbows after removal, notice how the O rings are compressed flat. Here are the aluminum elbows that were installed and a picture of one that was installed. I couldn't get a clear picture the other one. I also replaced the upper and lower radiator hoses. Getting to the lower hose clamps wasn't easy, but I got it done and now all is as it should be. Quote

l67ss Posted January 4, 2015 Report Posted January 4, 2015 Example of why I dont like zzp.....theyre supposed to bo THE 3800 guys yet they include plastic elbows? And yes ALWAYS replace the o rings regardless of who made the elbows Quote
Psych0matt Posted January 7, 2015 Report Posted January 7, 2015 When did the aluminum elbows become stock? Quote
Addicted To Boost Posted January 7, 2015 Report Posted January 7, 2015 They didn't. Dorman makes the metal ones. Quote
Psych0matt Posted January 7, 2015 Report Posted January 7, 2015 I thought they did sometime for the third gens, or at least that's what I remember someone saying? Mine has one that could have been replaced before, but I didn't think so Quote
Addicted To Boost Posted January 7, 2015 Report Posted January 7, 2015 Nope. All OEM ones are plastic. I'd replace them with the metal ones ASAP. My 04 ate 3 sets of plastic ones during my ownership. Almost overheated it once, because it lost nearly all of its coolant on the highway when one broke. Quote
Psych0matt Posted January 7, 2015 Report Posted January 7, 2015 Is there more than one? I know I have at least one metal one Quote
l67ss Posted January 7, 2015 Report Posted January 7, 2015 Is there more than one? I know I have at least one metal one 2 on 99+ Quote
Imp558 Posted January 10, 2015 Report Posted January 10, 2015 Damn I never knew that we were supposed to replace the o rings! I did the aluminum one and it leaks too, now I know why. Where do we get the o-rings from to get the best ones? Quote
The Guz Posted January 10, 2015 Report Posted January 10, 2015 I replaced the dorman o-rings with delco o-rings. I ordered them from rock auto. I ordered qty of 5 of each. ACDELCO Part # 24502846 ACDELCO Part # 1534066 Quote
