Product Details

The Gates 21135 is a premium molded radiator coolant hose engineered for heavy-duty commercial truck and diesel engine applications. This pre-shaped upper radiator hose features a 2.5-inch inside diameter on both ends with an 8.5-inch centerline length, designed to provide a perfect OEM-quality fit.

Key Features:

  • EPDM tube construction with synthetic fiber knit reinforcement for superior durability
  • Heat-, ozone-, and chemical coolant-resistant EPDM cover
  • Engineered to resist electrochemical degradation, the leading cause of hose failure
  • Re-engineered materials resist vacuum collapse, reducing the need for internal springs
  • Includes internal support spring for additional reinforcement
  • Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications
  • Temperature rated from -40°F to 275°F (-40°C to 135°C)
  • Approved for marine applications

Gates molded coolant hoses are manufactured to OEM specifications for upper, lower, bypass, heater, and other coolant system applications. The pre-shaped design ensures perfectly sealed conditions and eliminates the time and expense of sourcing OEM dealer replacements. Cross-references to numerous OEM part numbers including Freightliner, International Harvester, Cummins, Caterpillar, and others.

straight forward order process, great price.

your phone rep was courteous and knowledgeable; I've bought the part needed from you and will spread the word!

Great pricing, free shipping, and great product!!! What we got was better than OE for 1/5 the price! Thank you!

Good company, good prices and great staff.

Best prices on the net! They had everything I needed at one site.

Your website failed when I was originally ordered. I only want 4 spark plugs not five. I had to order twice. Please bill me for 4 spark plugs not 5. Order #284592. Thank you, James

Good

Hands down the best price on the Magnaflow catback I have seen by more than 20%. They were able to work out the ship-from-manufacturer tracking after a quick phone call. Will definately be recommending these guys to others.

easy and simple.

Good price, great presentation and easy navigation.

Quick,easy,just the way every company should be. Thank you!
