Product Details

The Gates 18623 is a precision-molded small inside diameter coolant hose designed for modern engine compartments where space is at a premium. This factory-molded, OEM-style hose features a 0.25-inch (1/4-inch) inside diameter and 4.8-inch centerline length, providing an exact-fit replacement for throttle body to engine coolant connections.

Advanced EPDM Construction:

  • Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
  • EPDM rubber construction with synthetic fiber knit reinforcement for superior durability
  • Heat- and ozone-resistant materials ensure long service life
  • Temperature range: -40°F to +275°F (-40°C to +135°C)

Versatile Applications:

  • Suitable for coolant, water, and air applications
  • Approved for marine use
  • Meets SAE 20R3 Type EC Class D-1 and D-2 specifications
  • Pre-shaped design ensures perfect fit and proper sealing

Important Note: Not intended for fuel or oil transfer applications. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance and leak prevention.

So far so good

reordering last years part number was a breeze. thank you.

This is my first experience ordering from Autoplicity. I was searching for tires online and found that tire rack and Big O tires both listed the size/brand that I needed as out of stock. Auto closely said that they had many in stock and at the best prices. I was pleasantly surprised to receive them within 2 to 3 days. I will definitely be ordering from them again in the near future.

Thanks

My first order was delivered in under 48 hrs nice work thank you
