I have a 2005 Chevy Equinox and my heater hose assembly keeps on breaking. Why does it do that and does anyone have the same problem

What exactly breaks? Can you post a photo?

What breaks? Is a hose popping off? Is it overheating?

The reason the hose assembly breaks is because the plastic that’s used by the OEM can’t withstand the heat and vibration it’s exposed to under the hood.

The next time the hose assembly needs repair, instead of installing an OEM type part, install this instead.
