  • Install: It is recommended to use a heater hose disconnect tool to remove the old connector from the firewall. When installing the new fitting it will be a tight fit by design, it is recommended to use some soapy water to help slide the new fitting onto the heater core tube and make sure to keep pushing it until you hear or feel a "click". Be sure to clean all the crud off the heater core tubes before installing the new fitting. Secure the heater hose with the included clamp.

I only used one of these on the truck to stop a leak. Works good so far. Used in on Feb 18 2025. Only time will tell how long it goes for.

These couplings fit very well was easy to replace on the current heater hose. I just had to cut off the old ones and I added those with the clamps fit very well snapped into place. Don’t have any leaks and they look like they made a lot better than the ones that I took off
