Gates Radiator Coolant Hose P/N:51722
Gates 21256 radiator coolant hose for the 1986-1991 Mitsubishi Fuso FM truck 6-cylinder 6.6L, the 1990-1991 FM truck 6-cylinder 7.5L and other vehicles and equipment carries coolant through the cooling system. This listing is one molded hose.
Cracks, soft or swollen spots, or coolant seepage at the hose can mean it is worn. Look only with the engine off and cool. Before you replace the hose, rule out a loose or failed clamp or another leak source, since the same signs can have other causes.
The 1986-1991 Mitsubishi Fuso FK truck 6-cylinder 6.6L and the 1988-1991 Mitsubishi Fuso FH 6-cylinder 5.0L take this hose too, along with other vehicles and equipment, and each application takes one. Open the "Vehicles it fits" section to check your exact model and engine.
