RPC Flex Hose 38Mm X 38Mm X 355

Your vehicle relies on the performance of the engine and your engine relies on the performance of the cooling system to keep it at the optimal running temperature. Gates direct fit molded radiator hoses are designed to match or out-perform OEM quality, flow and fit. All Gates radiator and heater hoses have a heat and ozone resistant cover and are engineered to resist electrochemical degradation (ECD) which is the leading cause of premature hose failure. The research and development team at Gates makes sure every radiator hose developed meets SAE 20R4 and 20R3 specs and are tested to withstand -40 to 135 degrees Celsius for all types of weather extremes that you throw your car at. Keep your engine at optimal running temperature all year round by maintaining your cooling system on a regular basis, make sure you check and top up your coolant, check for leaks around the hoses and radiator, feel for hose weakness from electrochemical degradation (ECD) and tighten up any loose radiator hose clamps. For best results we recommend servicing your cooling system every 4-5 years by flushing the system, replacing radiator hoses, thermostat, coolant and in some cases the heater hoses. Doing preventative maintenance like this on a regular basis makes for worry-free driving all year round without the fear of unexpected breakdowns on the side of the road. How to check coolant hose for the effects of ECD: Make sure the engine is cool Use fingers and thumb to check for weakness Squeeze near the clamps and connectors ECD occurs within two inches of the ends of the hose - not in the middle 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 and should be replaced immediately to minimize failure
