Extended Product Information

FAQs

Is this hose compatible with all W124 models?

While designed for the W124 and C124 series, you must check your specific engine variant and compare it against OEM reference number 1248302496.

What is the exact length of this hose?

This hose is 255mm in length.

Does this package include clamps?

No, this product is the hose only; you should reuse your existing clamps or install new ones if the old ones show signs of corrosion.

How often should heater hoses be replaced?

Generally, it is recommended to inspect heater hoses every 40,000 to 60,000 miles or whenever the cooling system is serviced for leaks or cracks.

Can I trim this hose if it is too long?

The hose is precision-cut to 255mm for specific fitment. Trimming is generally discouraged unless specifically required by your vehicle's specific configuration.

Troubleshooting

Coolant leaking at the connection point

Check that the clamp is tightened securely and that the hose is fully seated over the nipple; ensure the clamp is not placed over any debris on the port.

Hose appears kinked or bent

Verify the orientation of the hose ends. If the hose is kinked, loosen the clamps and rotate the hose slightly to find a more natural path without tension.

Pros and Cons

Pros

  • Meets stringent OEM quality standards
  • Precise 255mm length reduces installation errors
  • Direct compatibility with specific Mercedes-Benz 124 series models
  • Highly resistant to coolant-related degradation

Cons

  • Specific to select Mercedes-Benz models only
  • Requires manual verification of OEM numbers before purchase
  • Must be handled carefully to avoid kinking during installation

Setup, Compatibility & Care

Before installation, ensure the engine is completely cool to prevent coolant burns. Verify your original hose part number against OEM reference 1248302496 or A1248302496. To install, loosen the existing hose clamps and slide the old hose off the heater core and engine ports. Clean the metal connection points of any debris or oxidation before sliding the new 255mm Gates hose into place. Secure it with high-quality worm-gear or constant-tension clamps, ensuring the hose is not twisted during tightening. After installation, top off the cooling system with the manufacturer-recommended coolant, run the engine to operating temperature, and check for any signs of seepage.
