Review on 🔥 Enhance Heating Efficiency with the Motorcraft KH-509 HVAC Heater Hose Assembly by Robert Morrison

Replaced the heater hose on 07 Expedition. Perfect fit (after you remove the extension from the firewall as others have said) Next time you get another Want to replace hose (with a Y connector) Revain fitted it to a Motorcraft KH-451. The picture doesn't match the actual hose so it's hard to find. I also ordered both special tools. The long black rod I couldn't get to work.Quick connect stacking tools only worked on simple connections.I used 11" 90 degree needle nose pliers (although the packaging says 45 degrees) to get into the hard to reach places to get near the firewall.This tool I've had good luck with them.Just use the white tabs on the end of the quickv squeeze the connector, twist and pull the hose. Reconnection has also been simplified by removing the other heater hose i easier access Please note that when replacing a different heater hose you do not need to remove the two firewall extensions for that hose. The replacement hose really needs extensions.
