Title: Heater Core Tee Connections?
Post by: andrew on January 01, 2016, 12:38:09 pm

Does anyone happen to have a part number? I am in need of a reducing T for my diesel swap. I need to join the 5/8 ID reservoir connection into the 3/4 ID heater core hose. I suspect that this is the same as those white T parts near the firewall on models with a rear heater core.

I can't find these anywhere! I can't even find a diagram referencing their existence. Greasecar sells something that would work but has a minimum order of $25.

Any Ideas?

Napa auto parts has 5/8-3/4 straight reducers (black thermoplastic) or a good pipe fitting shop will have these in brass. McMastercarr.com prob carries a 3/4-5/8 T reducer but I haven't looked so don't know for sure.

Amazon has some nice brass brass fittings too

I ended up using a little vegetable oil and sliding the hose onto a 3/4 fitting. It seems to be working fine for now.

Couldn't find anything at either Amazon or McMaster, or really anywhere else. Must be close enough to 3/4 to not bother.
