Four Seasons 56452 a/c refrigerant liquid hose for the 2002-2021 Freightliner M2 106 and other vehicles is a liquid line hose assembly that carries refrigerant through the A/C system.
- Engineered and tested for years of trouble-free operation, with over 50 years of mobile A/C experience behind it
- Double wall barrier hose compatible with R1234YF, R134A or R12
- Crimp fitting connection
- Application specific design
Oily residue at a fitting, a cracked or damaged hose, or A/C that cools poorly can all point to a hose problem. Before you replace this hose, rule out a low refrigerant charge or a failed component elsewhere in the system, because weak cooling has more than one source. A shop can test the system for leaks.
The vehicles it fits include the 2003-2021 Freightliner M2 112 and the 2005-2020 Freightliner M2. If your truck is not named here, look it up in the "Vehicles it fits" section, which also covers engine details.
