Question about 1999 GMC Suburban
Engine temp. goes to 210 + on gauge, but will return to normal operating temp if you turn blower to high, but will return to the 210 + as soon as heater blower is turned down. Van has good heat but is getting me worried. Could the thermostat need to be replaced?
Jt\\it could be the water pump or the thermostat giving you problems
