Just need confirmation on heater hose sizes

[s-m-h]

Hello again gang!

I am replacing all rubber hoses on my coach. Fuel, vacuum, upper and lower rad, and heater hoses.

On the heater hoses I am going to bypass the rear heater for now and just want to confirm the sizes going to/from the heater core.

My belief is the one coming from the top rear of the intake manifold is 3/4" and the one going from the front of the engine to the inlet of the heater
core is 5/8".

Can you fine folks confirm or correct my thoughts please.

TIA

for sure 5/8" and 3/4"!

had to bypass the heater core a week ago when it let go. I only had a 5/8 or a 3/4" barbed splice. Had to jam the 3/4" splice into the 5/8" hose
to connect the two hoses together.

Shawn, if you're asking about the long heater hoses going back to the "heater core", they are 5/8" and actually go to the water heater.

I need to make that a little more coherent.

Shawn, if you're asking about the long heater hoses going to the back of the coach, they are 5/8" and actually go to the water heater. (Unless your PO
has added an aux heater.)

Im bypassing (not using) the ones to the rear of the coach for now. Only concerned was with the 2 hoses from the heater core to the engine and I think
i got my answer above.

Thanks
