Put on a new water pump and the simple task of slipping the water tube with O ring into place has me stopped cold. Everything is clean and I put O ring on the tube, lubed, and try to gently work into place but so far has cut or broken the O ring 3 times. There must be a trick to this?? I used tire bead lube the last time and still the same. I must be doing this wrong. I'm trying to push it in straight down with a tiny jiggle as I do. Any pro's out there? I'm at present out of O rings but will restock soon. Thanks, LB

Thats odd leakyboot. I would suspect a sharp edge on the new water pump. They usually push in fairly easy with some lube . I have used silcone RTV in the past and worked fine. Its pretty slick plus helps seal after it sets up.

Make sure you have the correct oring and the chamfer on the bore is nice and smooth.
