201fireman Posted March 29, 2020 Share Posted March 29, 2020 I am finishing up my SBC to BBC swap. I have a Meziere electric water pump. It does not have the heater hose tap on top like the mechanical one did. Where do I run the heater hoses to? I am guessing one would go where it did before, on the top front right of the manifold, but the other one??? Is there a diagram anywhere that shows the cooling system and how it flows?

Andy's Auto Posted March 30, 2020 Share Posted March 30, 2020 once you go electric, you are pretty much giving up your heat. Quote Link to comment Share on other sites More sharing options...

201fireman Posted March 30, 2020 Author Share Posted March 30, 2020 I just found out that I can send the return line that used to go to the water pump, to the upper right corner of the radiator if I have the extra bung on it... which I happen to have on my new radiator! I love it when a plan comes together. 1 Quote Link to comment Share on other sites More sharing options...
Andy's Auto Posted March 30, 2020 Share Posted March 30, 2020 Pretty sure the 88-95 Silveraydo bolt right in and have that nipple. I missed the Wisconsin thing. In South Florida, heat is for getting the dew off the windshield 66 days a year. If you leave for work before dawn. I almost never have to fix heaters down here.

201fireman Posted March 31, 2020 Author Share Posted March 31, 2020 Not sure I would use it alot. The feed from the manifold to the heater core is a 5/8". The return from the core to the water pump (or now to the radiator bung) is a 3/4", but the bung is a 5/8". Think it makes a difference which way the coolant flows through the core? I am thinking about swapping the lines so the 5/8" runs back to the radiator bung. Quote Link to comment Share on other sites More sharing options...
