Car manufacturers are designing the majority of new coolant and heater hose parts as branched/modular assemblies. This is particularly by European vehicle manufacturers, as European makes have the highest percentage of branched/modular hose. As such Gates^® will continue to expand the range to offer aftermarket replacement.

Hoses now have quick-connects, sensors, restrictors, valves and other components built into the hose, and this transformation is going to continue. The quick-connects and brackets are for easy-of-assembly and orientation T's are used to route additional hoses to new vehicle systems requiring cooling.

Cooling systems now have 50 psi constant pressure with spikes of 70-80 psi. Standard clamps over a barb cannot hold this pressure and quick-connects with an over-mold clamp are required. Check-valves and flow-restrictors are needed to control the coolant flow. Hoses must use the latest reinforcement technology to be able to handle these pressures. 

Gates^® has a comprehensive range for popular makes and models and comes with features such as:

• Factory quality connections that are durable and eliminate coolant leaks
• Engineered to resist electrochemical degradation – the leading cause of hose failure
• Heat and ozone resistant cover
• Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications
• Temperature rating: -40°C to +135°C in coolant hose applications
