[quote:0c2239e7be="tbear1955"]Heater problem
1998 Buick Century 6 cyl Front Wheel Drive Automatic 108000 miles
----------------------------------------------------------------
the car will not continously heat, replaced water pump, thermosat, back flushed coil, the higher the idil the better the heat, otherwise blows cold[/quote:0c2239e7be]
it sound like a low coolant flow throw the heater core
Engine cool
lower the coolant level
Locate the two hoses running to the heater core
disconnect them at the engine side leaving hoses connected to heater core throw the firewall
use garden water hose and compressed air if possible
run the water and follow by air throw one side and out the other and vice versa
do that two to three times watching what leaving the heater core you are looking for the good flow and clear water to run throw
good luck
let me know
