Q: Would radiator flush clean out the heatercor

asked by on

Okay the water pump got replaced in my car, afterwards the heater quit blowing got, there was a bunch of hold up in the radiator. Would radiator flush help clean out both the radiator and heatercor

My car has 175 miles.
My car has an automatic transmission.

The heater core may get a little cleaned if you use a flush and hold the rpms at about 1000 for 5 minutes with the heat on. If the heater core is completely clogged then you may not get any flow through the core and will need to take off heater hoses and back flush the core using a garden hose.
