Wehrli GM Billet Heater Core Fitting Kit w/ Hose

If your GM vehicle's heater core fitting is starting to leak, it's time to replace it with a more reliable part. This billet aluminum fitting kit from Wehrli Custom Fab is designed to replace the often problematic factory quick-connect fitting, helping to prevent coolant leaks and ensure your heater system works as it should.

The kit includes a precisely machined billet aluminum quick-connect fitting that uses serviceable O-ring seals. These seals install easily with a bit of lubricant and are held in place by a wire retainer clip, making installation and future removal straightforward without needing special tools. It also comes with a preformed, universal 1/2-inch heater hose assembly, so you have everything you need to get the job done.
