Customer: Hi. I have a Chevy S-10 pickup with the 2.2 motor. The heat doesn't come on. I changed the thermostat, no help. The temp. gauge doesn't work either. The hoses going to the heater core
in the car are both cold so no anti freeze is getting to the core. Is there a sensor that controls the gauge and a valve for the heating unit?
JA: Thanks. Can you give me any more details about your issue?
Customer: The head gasket
was changed this summer, but since then the heater worked and the gauge worked. the coolant is up and good. The thermostat is working, because when the engine
is warm, both inlet and outlet hoses to the radiator
are warm. When the heat switch inside is turned to full hot, neither heater hose gets hot. Anti-freeze isn't circulating into the heater core is my guess.
