Q: Heating hose has a pin hole in it

asked by on

The heating hose has a pin hole in it on the top side of the engine.

If one of your engine’s coolant hoses has sprung a leak, it probably needs to be replaced. Leaks in the cooling system will cause the vehicle to overheat, and experience other problems. I would recommend having a professional technician, such as one from YourMechanic, replace the heating hose, and inspect the vehicle for any other possible problems.
