kirkynut Report post Posted November 2, 2019 Were you careful to lubricate the seals with something to prevent them from tearing? I use a little red rubber grease. Perhaps take it all apart and re-fit with some red rubber grease to make sure that you have it all fully seated with no sticking points. Dry seals might seem fully seated but may not be. I found coolant does not act as a good enough lubricant and could see the joints were not fully seated and have the grease, so used it with good results.
