Can someone tell me what is involved to replace both coolant elbows on my L67 engine? TIA!
I went to NAPA and got the "upgraded" ones. We will see how it all goes. Thanks for the information.If you get the Dorman Coolant Elbow Kit be sure to take the o rings off of it and get the AC Delco ones, or Fel-PRO ones, the Dorman ones are known to leak, and I've heard that Dorman has started looking into the problem, but no recalls have been issued.
They will however replace them for you if they have failed.
ACDELCO Part # 1534066 should fit all 3 but the bigger part on one of the elbows, I just went with the Dorman purple one for that o ring, and so far no leaks.
Of course my purple on is on an aluminum nipple that is part of the belt tensioner assembly because my car is not supercharged.
Should still work fine though.
There is supposed to be an "improved" version of the elbow/o rings, it has production code number of 11300 or higher stamped on the elbow, this info comes from rkpatt on another forum..
Sweet, hope it works well, I have a feeling it will since I bet they changed the o-rings that were made for them.I went to NAPA and got the "upgraded" ones. We will see how it all goes. Thanks for the information.
Does that fix the known problematic Dorman O Rings?RTV the O-rings or the will leak damn near everytime
There weren't scratches, just some corrosion from where the old original elbows had leaked. Even then, it was so slight, I never would have dreamed it would cause a leak, particularly with the new GM elbows and O-Rings!
Anyhow, like you, I skim-coated the elbows and bores and it all went together fine and remains leak-free.
Ideally, the bores could be machined and have a stainless insert pressed-in to restore proper dimensions and eliminate the possibility of corrosion. Nice if this would have been done new from GM, but I don't think they ever envision most of their cars lasting longer than 5-years!
Also interesting is that GM easily could have added a second O-ring on each elbow, and perhaps even a third to make an absolutely leak-proof and long lasting seal.
I'm guessing GM's corporate bean-counters have more pull than engineering in these types of decisions which is too bad for all of us... anyhow, the leak is fixed for now!
The best way to replace the coolant elbow is to remove the water pump and insert the new elbow before inserting the bolts for the water pump. Check that there are no pieces of the old plastic elbow lodged inside. Replace both elbows if so equipt at the same time. If you need additional information look for some other auto repair for replacing coolant elbow.Can someone tell me what is involved to replace both coolant elbows on my L67 engine? TIA!
If you have never replaced your lower intake manifold gasket with the aluminum framed gasket, then the guy was doing you a favor by suggesting you change those out, he should have asked if you ever had them replaced before suggesting you get the kit though.I recently had the elbow on my 02 grand prix gt explode litterally and when i went to autozone (never having this problem before) the guy sold me an entire gasket kit and told me i had to replace manifold gaskets, and all kinds of other o rings and stuff but from what i read on here it doesnt sound like any of thats necessary.. ill be sticking with oreillys from now on
