LR, Check carefully for pits where the tube resides in the water pump housing and fill with JB Weld. Make sure there are no dings on the end of the tube. Use nothing other than some spit or (even better) KY Jelly as a lube to ease insertion of the tube. If an o-ring cannot do its job on its own, using a foreign substance will NOT make it work any better. You MUST use the correct O-ring. It is yellow and is made of a more pliable substance than normal black o-rings. IIRC, it is 5x25 mm.

Previously I had stated this upper aluminum water tube that pops into the water housing w/ only an oring was pretty bent up. I've since cleaned, straightened it to where I believe it has a chance... I'm ready to install it, but decided to ask the list if anyone has used any other sealant other than blue RTV for cooling on the Oring to confirm a proper seal? Is there a better sealant to use for water outlets/heat? Thanks, LR |
