Keep coolant moving through your Mercedes-Benz cooling system with the Gates Modular Coolant Hose 51418. It fits the 2012-2015 Mercedes-Benz C250 (L4-1.8L) as a direct-fit replacement, built to match specific applications and integrate the same OE-style components the vehicle uses — hose branches, quick-connectors, sensors and restrictors — so it drops into the original routing.
- Modular OE-exact design: manufactured with OEM-exact hose components (quick connects, branch connectors/tees, sensors, etc.) for application-specific fitment.
- EPDM construction: EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone- and chemical coolant-resistant EPDM cover.
- Collapse resistance: specifically-engineered materials resist collapse under vacuum.
- Degradation resistance: engineered to resist electrochemical degradation, the leading cause of hose failure.
Meets SAE 20R3 EC Class D1 under 25 mm (1 in.) ID and SAE 20R4 EC Class D1 for 25 mm (1 in.) ID and over, with a temperature range of -40°F to +257°F (-40°C to +125°C). Do not use for fuel or oil transfer applications. Gates recommends replacing clamps each time a new coolant hose is installed. Country of origin: Turkey.

What is this hose made of?
It uses an EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone- and chemical coolant-resistant EPDM cover, designed to resist collapse under vacuum.
Why is it called a modular coolant hose?
Gates manufactures it with OEM-exact integrated components such as quick-connectors, branch connectors/tees, sensors and restrictors, so it matches the application's specific routing.
Should I replace the clamps when installing it?
Yes. Gates recommends replacing the clamps each time a new coolant hose is installed. Consult your service information for the correct hardware.
Can I use this hose for fuel or oil lines?
No. This is a coolant hose only — do not use it for fuel or oil transfer applications.
