No heat

[steve from staten island]

I have a new classic ac system. Had some issues but everything seems to be working properly. The defroster, floor dash control all work correctly. The heat switch opens the water control valve when switched to "hot". Water temp was up to around 170 degrees but still the unit blew only slightly warm at best. The hose's are on correctly but i notice they do not get hot as they should. I could squeeze them (with engine hot and running) and not feel any resistance as in flow. Whats up? Any thoughts?

The other thing is the flow of coolant in radiator. I see movement but not a lot. The gauge only goes up a third of the way and the car is not overheating

heating coil tubes clear? air vented? doors in correct sequence? (my ram was a royal pia)
i'm sure your car runs normal temps.
if not, water pump impeller?

Trapped air? Bring up the revs on a test drive, floor it.

Be sure you don't have any air lock.
