• Straight hose designed for demanding heavy-duty coolant/air applications.
• Engineered to resist electrochemical degradation (ECD®) – the leading cause of hose failure.
• Two-ply bias fabric construction to maximize flexibility and strength.
• Resists “cold water leaks” at clamp connections.
• Advanced EPDM tube cover stays soft and pliable, even under adverse operating conditions.
• Resists water loss from water permeating through the hose wall and cover -- a distinct advantage over silicone.
• Temperature rating: –40°F to +257°F (–40°C to +125°C)
• Packaging: 3-ft. lengths.
• Exceeds SAE 20R1 Type EC (Class D-1 Tube, and cover, Standard Wall) specifications.

NOTE: For a maintenance free connection, use Gates PowerGrip® SB Clamps.

Signs it is Time to Replace Your Coolant Hose(s)

Prevent system contamination and coolant leaks that could cause your engine to overheat by checking for these common signs of Coolant Hose damage / failure:

INTERNAL DAMAGE
Soft / mushy hose ends, usually about 2 inches from the clamp. Internally Damaged Hose

LEAKAGE
Moisture, drips or coolant bleed marks on or around the hose clamps, connectors or hose. Leaking Hose

HEAT DAMAGE
Slight swelling, or a hardened, glossy cover that is covered with cracks. Heat Damaged Hose

OZONE DAMAGE
Tiny, parallel cracks in the cover, usually at hose bends. Ozone Damaged Hose

ABRASION DAMAGE
Rubbing marks on, or damage to the hose cover. Abrasion Damaged Hose

OIL CONTAMINATION
Soft or spongy to the touch - bulges and swelling are readily apparent. Oil Contaminated Hose
