Good Day, All
I am looking to verify that my heater hoses are properly connected. Any help would be appreciated
-Standing in front of the vehicle looking at the firewall....inlet to the heater core, is it the tube on the driver side or the passenger side?
-Standing in front of the vehicle looking at the water pump housing.....there are two nipples (one closer towards the radiator and one behind towards the distributor). Which is the inlet and which is the outlet?
-Also, I have an aftermarket valve like the one pictured. am I correct in assuming the upper passage is the one that controls the flow to the heater core inlet by opening and closing the valve, and the lower passage is just a flow thru return line from the heater core outlet back to the engine (water pump housing inlet nipple)?
Thanks much
