Coolant Elbows

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.

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

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.

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?
