This Gates Molded Heater Hose is an OEM spec replacement for Vauxhall vehicles. It is designed for various automotive coolant hose applications including upper, lower, bypass, and heater hoses. The hose cover is resistant to heat and ozone, and the Gates coolant hose formulation resists electrochemical degradation, which is a leading cause of hose failure. It is made from EPDM (ethylene propylene diene Monomer (M-class) rubber). The inner diameter is 20 mm and 15 mm, and the hose length is 560 mm. This part fits the VAUXHALL CALIBRA 2.0 LHD Only 90 to 94 C20XE models. Cross-references include RAPROR18206 and compatible OEM references from OPEL and VAUXHALL such as 1818073, 1818162, 90287171, and 90409804. Other references include 4275-22489.
