Heater core done again

RTguy said:

Had my heater core replaced along with the thermostat last year because it wasn't functioning properly. The heat from the vents was coming in as waves of cold and hot.

Fast forward to today, heater core is done again. Vents are blasting cold air and hot air in waves.

I bought a cabin filter and installed it shortly after I replaced the first one as I had assumed the lack of a filter was to blame for my faulty heater core.

What could cause a brand new heater core to go bad within a year??

Double check the thermostat and make sure that the coolant level is correct. Make sure you aren't loosing coolant while the degas bottle isn't introducing coolant back into the engine. Engine could be low and the bottle is still full!

Also typically if everything else is good than an improper coolant will accomplish what you are experiencing again!

When we mention that we don't have the "gunk" in QuantumBlue HP Gold Coolant, what we mean is that there isn't any sodium silicates, sodium benzoate and no sodium tetraborate along with a lack of sulfates that turn to silicon dioxide!

This is what ends up in the radiators, heater cores and the blocks of the engines. HOAT means Hybrid Organic Additive technology. Read organic as Inorganic and organic Sodium!

This is why we convert so many people here over to our QuantumBlue HP Gold Coolant so that you avoid these crappy situations.
