PHH or the "Pesky Heater Hose" is known to be a pain to change, and as part of the cooling system it will disable the vehicle when it fails, and usually at the worst possible time.
So when it is due for replacement use only OEM quality parts to ensure it will stand the test of time.
Mechanics TIP!
When in doubt replace the hose and the pipe in one go by purchasing just a single part below.
