Four Seasons 55178 a/c refrigerant discharge hose for the 2003 Toyota 4Runner, also called a discharge line hose assembly, carries refrigerant away from the compressor on the high-pressure side of the A/C system.
- Engineered and tested for trouble-free operation, backed by over 50 years of mobile A/C experience
- Double wall barrier hose compatible with R1234YF, R134A or R12
- Crimp fitting connection
- Application specific design
Oily residue around the hose or its fittings, visible damage, or an A/C system that cools poorly can mean the hose is worn. Before you replace it, rule out a low refrigerant charge or a compressor fault, since weak cooling has other causes too, and a shop can test the system if you are unsure.
This hose is a direct-fit replacement for the 2003 Toyota 4Runner.
