Gates 52174 Modular Molded Coolant Hose 11/16" x 3/4" x 26-3/4" with Female Quick Connector

The Gates 52174 is a premium Modular Molded Coolant Hose engineered as a direct OEM-quality replacement for today's complex engine cooling systems. Measuring 11/16" x 3/4" x 26-3/4", this hose includes an integrated female quick connector and protective sleeve, matching the exact configuration of the original equipment it replaces.

Gates leads the automotive aftermarket in modular assembly coolant hoses. This hose is manufactured to fit specific applications and integrates essential OE components — including quick-connectors, branch connectors, sensors, and restrictors — so no additional adapters or fittings are required for installation.

Key Features:

• EPDM construction: EPDM tube with synthetic fiber knit reinforcement and heat-, ozone-, and chemical coolant-resistant EPDM cover
• Electrochemical degradation resistance: Engineered compounds combat the leading cause of coolant hose failure
• Vacuum collapse resistance: Re-engineered materials maintain hose shape under negative pressure
• OEM-integrated components: Female quick connector and protective sleeve included — no extra hardware needed
• SAE compliant: Meets SAE 20R3 EC Class D1 (under 25mm ID) and SAE 20R4 EC Class D1 (25mm ID and over)
• Wide temperature range: Rated from -40°F to +275°F (-40°C to +135°C)

Note: Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a proper, leak-free seal.
