FAQs

How do I confirm this hose fits my car?

You must verify that your vehicle's original heater hose part number matches the OEM reference: 64211391387.

Does this hose come with installation clamps?

No, this product typically includes the hose only. It is recommended to use the existing clamps if they are in good condition or replace them with new ones.

Can I use this for non-coolant applications?

No, this hose is specifically engineered for automotive coolant systems and should not be used for fuel or oil transport.

What is the expected lifespan of this hose?

While lifespan depends on usage and driving conditions, high-quality replacement hoses typically last several years before needing inspection for signs of wear.

Should I replace the coolant when replacing the hose?

Yes, it is standard practice to use fresh, manufacturer-recommended coolant when performing any service on the cooling system.

Troubleshooting

Coolant leaking at connection point

Ensure the clamp is positioned correctly behind the hose bead and tightened sufficiently without over-compressing.

Hose appears to collapse when cold

Check the radiator cap pressure rating and ensure there are no blockages in the heater core or coolant lines.

Heater blowing cold air

Verify the cooling system has been properly bled of air and that the hose is not kinked, preventing circulation.

Setup, Compatibility & Care

Before installation, ensure the engine is completely cool to avoid thermal burns from pressurized coolant.

  1. Verify Compatibility: Cross-reference the part number 02-1746 with your vehicle’s OEM part number 64211391387.
  2. Drain System: Partially drain the cooling system to a level below the heater hose connection point to minimize spills.
  3. Remove Old Hose: Loosen the retaining clamps and gently twist the old hose to break the seal before removing.
  4. Install New Hose: Slide the Gates hose onto the fittings, ensuring it is seated fully past any barbs or beads on the connection pipe.
  5. Secure Clamps: Position the hose clamps appropriately and tighten them to the manufacturer's specified torque.
  6. Refill and Bleed: Refill the coolant reservoir and perform a bleed procedure to remove air pockets from the system.

Regular maintenance involves visual inspections during every oil change to check for bulging, brittleness, or evidence of white coolant residue near the connection points.
