Can Clogged Heater Core Prevent Coolant From Reaching Temp?
I have had 3 coolant flushes after seeing rust gunk in the reservoir. I had an OEM thermostat replacement, new coolant reservoir and cap (no radiator cap on this car) and water pump. Pressure tested as well. I was told when the t-stat was replaced that the heater core was no good.
My heat is weak, the car takes longer than it should to warm up. The coolant temp gauge rests BEFORE the middle since last month, it has always quickly moved to the middle before this.
Before I blow more money on it, could the heater core or radiator cause the cooling system to run too COLD? Engine seems/feels like it's in operating temp. Reservoir is also not pressurized very much. Before new water pump it was cold and had no pressure.
Can someone please help me fix this problem?
Forgot to mention that both heater core hoses are hot. Upper radiator hose is hot but no as hot as it should be.
