Description

Keep coolant moving cleanly through the heater circuit with the Gates HVAC Heater Hose 51378, a premium modular coolant hose that installs at the heater outlet position. It's a direct-fit replacement for the 2005-2008 Audi A4 and 2005-2008 Audi A4 Quattro with the L4-2.0L engine, built to fit that specific application with the essential integrated component molded right into the assembly.

Modular assembly: a molded coolant hose manufactured with an OEM-exact female quick connector so it drops in like the original routing (no branches on this hose).
Durable EPDM construction: EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone- and chemical-coolant-resistant EPDM cover; specifically engineered materials resist collapse under vacuum.
Electrochemical resistance: engineered to resist electrochemical degradation, the leading cause of hose failure.
Rated to spec: meets SAE 20R3 EC Class D1 under 25 mm ID and SAE 20R4 EC Class D1 for 25 mm ID and over, with a temperature range of -40°F to +257°F (-40°C to +125°C).

Centerline length is 19.75 in (502 mm), with a 0.7 in (18 mm) inside diameter at one end and 0.88 in (22 mm) at the other. Gates recommends replacing clamps whenever a new coolant hose is installed. Do not use for fuel or oil transfer applications. Country of origin: Turkey.
