Hi Doug

The heater return on the Renesis is from memory into the manifold that feeds water to the pump inlet.
This manifold has the following inputs:
a. Cooled water from the radiator
b. Water used to warm the throttle body
c. Heater return

Cheers

Greetings:  One more silly question as I attempt to plan out my water and oil runs…

The water for the heater core I know comes out of the block underneath the oil filter pad, but is there a consensus on where it’s best to return it to?  I hate to “assume” anything on this installation, but if I did I’d imagine I should be able to return it to the radiator by Teeing it into another line already heading there, etc.  

Is that what you all have done?  

Thanks!
