My lower radiator hose has a small leak where it connects to the water pump. I dealt with this last year and am NOT going to this year. Besides the corbin clamp I also added a band clamp. Now the casting on the water pump does have its share of pits for all the years, but I wiped it down with alcohol, clean the inside of the hose and use high temp silicone and it still leaked. Any suggestions? Something other than silicone?
It makes dealing with it in the future kind of a PITA, but I've used 3M weatherstrip adhesive (the sticky yellow stuff) on pitted/problematic hose connections. With everything clean and DRY, apply the weatherstrip adhesive on the fitting and I.D. of the hose (you don't need a ton), slide the hose on, wipe off any residual adhesive, install the clamp and let it dry. I've never had one leak! :2thumbs:
Thanks, I'll give that a try. I forgot, but any suggestion on having the valve cover gaskets not leak? I've got alum. heads and am using the thicker NAPA gaskets that are on the harder side if you feel them.
Use fel pro cork/rubber valve cover gasket and this... let it dry for 24 hrs. or more.
Got some yesterday along with the Fel-pro performance gaskets. I have to get the 3/16 thick because the roller rockers just tap the top of the valve cover if I don't use them. I also got the 3M yellow weather strip for the hose. Of course now because of wiping that stupid leak several times last year the ink off my repro lower hose is gone. You can barely see it so I'm debating if I should even bother replacing it. Anyone have suggestion as to who makes the best repo hose with correct ink? OR, are they all made by the same place and different people just sell them?
