  • OEM quality, fit and performance
  • Heat and ozone resistant cover
  • Engineered to resist electrochemical degradation - the leading cause of hose failure
  • Hoses meet SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications
  • Temperature rating: -40 Degrees C to 135 Degrees C in coolant hose applications

Failure rates on radiator hoses increase dramatically after four years in operation. This is relevant to all coolant hose, but especially the top and bottom radiator hoses.

The primary cause of coolant hose failure is an electrochemical attack on the rubber compound in the hose.

This phenomenon is known as electrochemical degradation, or ECD. It occurs because the hose, liquid coolant and engine/radiator ?ttings form a galvanic cell or “,battery”,. This creates a chemical reaction which causes micro-cracks to form in the hose tube.

Coolant seeps into these cracks or stryations and begins to break down the reinforcement. This leads to hose failure and ultimately roadside breakdowns.

Gates moulded coolant hoses are manufactured to fit specific applications. Approved for marine applications
Not suitable for fuel or oil transfer applications.

Preventative Maintenance Guide:

As there is no way to tell from a simple visual inspection if a hose has internal damage, Gates recommends that all cooling system hose should be inspected at least once a year for damage from the major hose enemies, including electrochemical degradation (ECD), heat, oil, abrasion, ozone and leakage.
The best way to check coolant hose for the effects of ECD is to squeeze the hose near the clamps or connectors using the following procedure:
1. Make sure the engine is cool.
2. Use ?ngers and thumb to check for weakness.
3. Squeeze near the clamps and connectors. ECD occurs within two inches of the ends of the hose - not in the middle (See image for correct position).
4. Check for any difference in the feel between the middle and ends of the hose. “,Gaps,”, or “,channels,”, can be felt along the length of the hose where it has been weakened by ECD. If the ends are soft and feel mushy, chances are, the hose is under attack by ECD.

To avoid the risk of a burst hose and a subsequent breakdown of the cooling system, Gates engineers recommend replacing the hose immediately.
