Re: 02 Buick Lesabre Coolant Leak...

I still ...

Re: 02 Buick Lesabre Coolant Leak...

I replaced the plastic elbows again today and used the Ultra Copper RTV this time. I think I found the reason it leaked again this time.

Re: 02 Buick Lesabre Coolant Leak...

I recently changed the 2 plastic elbows. I put a very small amount of petroleum jelly on them. They seemed very loose when inserted. Everything was dry as a bone for over a week. Then it appears one of the elbows is leaking again.
