Product Details

The Gates 23921 is a molded radiator coolant hose engineered to deliver reliable coolant flow between the engine and radiator. Manufactured by Gates — a globally recognized leader in fluid power and power transmission solutions — this hose is built to withstand the demanding thermal and pressure cycles of modern cooling systems.

Constructed from premium EPDM (ethylene propylene diene monomer) rubber, the Gates 23921 resists heat, ozone, and coolant degradation, providing a longer service life compared to standard replacement hoses. The molded design ensures a precise, rattle-free fit that matches original equipment routing and geometry.

Key Features:

  • Premium EPDM rubber construction for superior heat and ozone resistance
  • Molded shape matches OE routing for a direct, leak-free installation
  • Reinforced inner plies resist collapse under vacuum and high-pressure conditions
  • Compatible with all conventional and extended-life antifreeze/coolant formulations
  • Manufactured to meet or exceed OEM specifications
  • Gates quality assurance — a trusted name in OEM and aftermarket cooling system components

The Gates 23921 is a dependable, professional-grade replacement hose suitable for restoring proper coolant circulation and preventing overheating. Ideal for technicians and DIY enthusiasts seeking an OEM-quality repair solution.

So far so good

Awesome! !!

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

Good site price reasonable

Pretty good. lets hope the delivery is as good.

Awesome deal

Great Company to buy parts from. They always have reasonable prices and reasonable shipping prices. Will buy from them again and again!

good prices not so good shipping rate

Loved it

Had just what I wanted at a very good price when I compared it to others (part plus shipping). Will try them next time I need parts.
