What does bypassing your heater core do?

Bypassing the heater core will effectively prevent the leak from happening but it cannot undo the damage that has already occurred as a result of the leak. There is probably a fair amount of coolant or water inside the heater core already in places that it wasn’t meant to get to.

What was the failure of my heater core hose?

I just experienced a failure of my heater core quick connect hose fitting over the weekend while towing my 10K# 5th wheel RV. I’ve read about this being an issue post failure. I wanted to share my experience and maybe help prevent this from happening to another.

Where are the heater core hose quick connect fittings?

Anyway, on with the show… The subject of discussion is a hose quick connect fitting that is located right at the firewall on the passenger side of the engine. Two rubber hoses attach to the heater core at this location via these quick connect fittings which the hoses are clamped to (I should have photos I know).

Is there a way to bypass the heater core?

Back to the exit ramp we went, and I grabbed my tool kit from the truck. I carefully cut the hose to get the broken barb fitting off then cut the other good hose in order to loop the hoses back on themselves using the Prestone T-fitting as a connector and bypassed the heater core.
