Hey guys. I changed my water pump about a year ago, and used the old "water pump inlet tube", but it would always leak a little anti-freeze. I tried buying a replacement from O'Reilly Auto Parts, but it is also a little loose, and not very snug. I think I might of widened the hole by messing with it too much. Any ideas on how to make this a tight, non-leaking fit? I thought about using teflon tape, but didn't know if that would break off inside the cooling system. Maybe I can use some sort of sealant around the edges, once I have it in there? I know that it will get super hot, so it has to stay good under intense heat. Any suggestions would be appreciated. Thanks!

 

Thats got a o-ring on it correct? I would try a thicker/fatter/ o-ring.

 

plan a - ^ thicker fatter o-ring with a little oil on it.

plan b - thicker fatter o-ring with a generous amount of rtv on it (clean off any oil).

 

I had the same issue, except mine was a brand new tube that came with the water pump. I just used rtv with the supplied o ring, and it hasn't leaked at all.

 

I've got some Super Blue Silicone Gasket Maker by VersaChem. http://www.oreillyauto.com/site/c/de...1759&ppt=C0137 Is that the same thing, or is there a brand/type you guys would recommend, that I can get at AutoZone or Oreilly? Thanks.

 

^ That'll work...

 

Sweet. Thanks!
