Modular hoses are on many of today's vehicles and are much more complex than the standard molded hoses of the past. Manufactured identical or equivalent to the OE hose, modular coolant hoses will keep your vehicle's cooling system running properly and efficiently for years to come.
Features & Benefits:
Engineered to resist electrochemical degradation (ECD®) – the leading cause of hose failure.
Eliminates water loss due to permeation.
Recommended for upper, lower, by-pass, heater and other coolant hose applications.
Heat and ozone resistant cover.
Installs easily without buckling, bending out of shape, or straining at connections.
Temperature rating: -40°F to 275°F (-40°C to 135°C) in coolant hose applications
Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications.
Gates recommends replacing standard worm drive and spring loaded clamps with PowerGrip® SB clamps each time a new coolant hose is installed. Do not use for fuel or oil transfer applications.
Signs it is Time to Replace Your Heater Hose(s)
Prevent system contamination and coolant leaks that could cause your engine to overheat by checking for these common signs of Heater Hose damage / failure:
Soft / mushy hose ends, usually about 2 inches from the clamp.
Internally Damaged Hose
Moisture, drips or coolant bleed marks on or around the hose clamps, connectors or hose.
Slight swelling, or a hardened, glossy cover that is covered with cracks.
Heat Damaged Hose
Tiny, parallel cracks in the cover, usually at hose bends.
Ozone Damaged Hose
Rubbing marks on, or damage to the hose cover.
Abrasion Damaged Hose
Soft or spongy to the touch - bulges and swelling are readily apparent.
Oil Contaminated Hose
