Route coolant reliably with the Gates Engine Coolant Bypass Hose 21841, a pre-molded EPDM hose that carries engine coolant on the bypass circuit — running from the intake manifold to the thermostat at the rear. It drops in as a direct-fit replacement for the listed applications: the 1988-1990 Ford Taurus, 1988-1990 Lincoln Continental and 1988-1990 Mercury Sable, all with the V6-3.8L engine.

  • EPDM construction: EPDM tube, synthetic fiber knit reinforcement, and a heat-, ozone- and chemical coolant-resistant EPDM cover.
  • Holds its shape: specifically-engineered materials resist collapse under vacuum.
  • Long service: engineered to resist electrochemical degradation, the leading cause of hose failure.
  • Pre-shaped fit: molded to fit and help ensure sealed connections.
  • Standards: meets SAE 20R4, class D2 and DIN 73411, class A (except for tolerances); rated -40°F to +257°F (-40°C to +125°C).

Centerline length is 9.3 in (236 mm), with a .61 in (15 mm) inside diameter at one end and a .75 in (19 mm) inside diameter at the other. Made in the United States. Gates recommends replacing hose clamps each time a new coolant hose is installed. Caution: do not use for fuel or oil transfer applications.
