heater return?

[C10Sim]

Where on the radiator is the heater return located?

Do you need a heater return for a vintage or old air underdash system?

it's not they should be in your water pump and intake

Return goes into the water pump above the lower hose. Water to the core comes out from the hole under the right side of the t-stat in the intake

Im a little confused, but the reason I ask was because I purchased a radiator and they ask if I wanted a heater connection?

Some year models returned to the radiator rather than the water pump. Order whichever you have now.

pretty sure A/C trucks returned to the rad... in all reality, it doesn't matter, one or the other.

I would recommend getting the radiator with the return connection. You can always cap it if you don't need but if you decide to convert, it's there.
