Description

Help keep coolant circulating and your engine at its proper operating temperature with the Gates Engine Coolant Bypass Hose 21187, a premium molded replacement hose. It's a direct-fit replacement for many vehicles, among them the 1980-1984 Volkswagen Jetta, 1975-1984 Volkswagen Rabbit and 1980-1984 Audi 4000 — see the "Vehicles it fits" section for the full list.

Molded to fit: Pre-shaped to route into the bypass circuit and seal properly, built to OEM-quality specifications.
EPDM construction: EPDM tube with synthetic-fiber knit reinforcement and a heat-, ozone- and chemical-coolant-resistant EPDM cover.
Vacuum & degradation resistant: Specifically-engineered materials resist collapse under vacuum, and the hose is engineered to resist electrochemical degradation — the leading cause of hose failure.
Meets standards: SAE 20R4 class D2 and DIN 73411 class A (except for tolerances), rated -40°F to +257°F (-40°C to +125°C).

Gates recommends replacing hose clamps each time a new coolant hose is installed. Do not use for fuel or oil transfer applications.
