Product Information

Full details

The Gates 05-3267 coolant hose is designed for automotive technicians and DIY mechanics seeking a reliable replacement for upper, lower, heater, or bypass cooling system connections. Its primary benefit is superior longevity due to advanced material engineering that resists electrochemical degradation, though users should confirm exact fitment for their specific vehicle make and model as hose geometry varies significantly between applications.

Extended Product Information

FAQs

Is this hose compatible with all coolants?

The Gates 05-3267 is designed to be compatible with most standard ethylene glycol-based coolants used in modern automotive systems.

Can I use this for fuel line applications?

No. This hose is specifically formulated for coolant and is not rated for fuel or oil exposure.

How do I know if this fits my vehicle?

You must cross-reference the Gates part number 05-3267 with your vehicle's specific make, model, and year using an automotive parts catalog.

What is electrochemical degradation?

It is a process where electrical current in the coolant causes the inner rubber of the hose to degrade, leading to leaks or blockages.

Should I replace the clamps when installing this hose?

It is highly recommended to use new, high-quality stainless steel clamps to ensure a secure, long-lasting seal.

Troubleshooting

Visible coolant weep at connection point

Check clamp tension and ensure the hose is seated fully past the radiator or engine port bead.

Hose feels excessively hard or brittle

This is a sign of thermal fatigue; the hose has reached the end of its service life and should be replaced immediately.

Pros and Cons

Pros

  • High resistance to electrochemical degradation
  • Heat-resistant outer layer prevents premature aging
  • Suitable for various cooling system positions
  • Built to meet strict OE performance standards

Cons

  • Fitment is application-specific and not universal
  • Requires professional installation tools for secure clamping
  • Proper cooling system bleeding required after installation

Setup, Compatibility & Care

Before installation, always drain the cooling system completely and allow the engine to cool to prevent thermal burns. When removing the old hose, inspect the mating surfaces for debris or scale; clean these areas thoroughly to ensure a leak-proof seal. When tightening clamps, ensure they are positioned correctly—not too close to the end of the hose to avoid cutting the rubber. For care, avoid using oil-based lubricants on the hose exterior, as these can degrade the ozone-resistant coating. Periodically inspect the hose for signs of hardening or persistent "sponginess" during routine oil changes to monitor the health of your cooling loop.
