heater return?

Where on the radiator is the heater return located?

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

Re: heater return?

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?

Re: heater return?

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

Re: heater return?

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

Re: heater return?

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.
