Really confused by my heater hoses. I have the water heater preheat loop in place.
The hoses running back to the water heater preheat are 5/8" for sure.
What size hose goes from the T at the back of the manifold to the heater core?
What size hose goes from the T at the front of the engine by the water pump to the heater core?
If I need to replace both Ts what sizes do I need?

Thanks!
