Question about 1997 Chevrolet Blazer
I replaced the thermostat but that wasn't the problem.... One of the heater hoses is hot, the other luke warm to the touch. I installed a "T" w/removable cap in the water pump heater hose to check flow - there was nothing at idle. Question 1: is the water pump hose the supply side? Question 2: is there a flow control valve in the heater circuit?
