Product Details

The Gates 19783 Molded Heater Hose is a precision-formed replacement heater hose engineered to restore proper coolant flow between the engine and heater core. Designed to match the exact routing and geometry of the original equipment hose, this molded hose eliminates the need for field bending or additional fittings, ensuring a leak-free, factory-correct installation.

Gates manufactures this hose using high-quality EPDM (ethylene propylene diene monomer) rubber compound, which provides excellent resistance to heat, coolant chemicals, and ozone degradation — delivering long-lasting, reliable performance under demanding underhood conditions.

Key Features:

  • Pre-formed molded construction matches OE routing for a precise, rattle-free fit
  • EPDM rubber construction resists heat, ozone, and coolant chemicals
  • Reinforced inner liner prevents collapse under vacuum conditions
  • Smooth inner bore promotes unrestricted coolant flow to the heater core
  • Meets or exceeds original equipment specifications
  • Direct replacement — no cutting, splicing, or additional fittings required

Gates is a globally trusted leader in power transmission and fluid power products, with decades of experience supplying both OEM and aftermarket automotive components. The Gates 19783 heater hose is an ideal choice for a dependable, OE-quality repair.

I searched the entire web looking for the best price on my item and found that Autoplicity beat everybody else in price & quality. Search no more!

Best price I could find on the net and super fast shipping.

Autoplicity had the best price on the VP fuel jugs, I ask if the could ship them out quickly and they did.

I placed an order,18852,for a Husky Liner on June 19th and received it on June 21st. They have a great price and low cost shipping.

Quick shipping, good communication, low price, would purchase again from this company.

Great
