Vintage Air Heating Problem 69 Camaro/LS1 I just installed a Compac Gen II vintage air/heat system in my 69 Camaro with a
2000 LS1. I filled the engine with coolant, started car, turned on the heater
controls once engine reach 180 degrees (48102-SVQ Vertical panel) and the air
coming out of the vents is cold! The hose with the heater control valve is not
hot when the engine temp has exceed 180 degree thermostat??? Here are my
connections:
I used the back fitting off the LS1 water pump (small opening) for the pressure
line going to the evaporator. I installed the heater control device in this
hose(flow arrow pointing towards evaporator) and connected it to the longer
water tube coming out of the evaporator (the one closest to the glove box).
The other hose was connected to the front fitting on the water pump (larger
opening) and it was attached to the shorter copper line coming out of the
evaporator (closest to firewall).
Anyone got any suggestions on why the heating system is not working? Before
installation I confirmed with a tech at Vintage Air the small opening on the LS1
water pump is the pressure line (heater control valve should be installed on
this hose) and that it didn't matter which heater tube is used on the
evaporator! Thanks in advance for any feedback concerning this heating issue!

I'm installing a VA system in my non-AC 70 Chevelle with an LS swap and find conflicting stories on which waterpump port is the intake side. Some say the smaller port feeds the control valve and the unit, but then I see diagrams showing the larger port is the out flow.
The VA picture doesn't mention anything about an LS.

heating The LS engine system was designed to heat the engine and cabin temp first for faster warm-up and when the thermostat opens, then coolant from the radiator will start to circulate thru the system, use the port that is on the engine side of the thermostat to feed warmed water to your heater.

Looks like that's what the OP did as well, yet he had issues. Did they ever get resolved and if so.....what was wrong?
