When creating our FleetRunner® Coolant Hose, we wanted to tackle the leading cause of hose failure: electrochemical degradation or ECD. This occurs when the hose, liquid coolant, and engine/radiator ﬁttings form a galvanic cell or "battery," creating a chemical reaction that allows micro-cracks to form in the hose tube. Coolant seeps into these cracks or striations and breaks down the reinforcement, leading to hose failure and, ultimately, roadside breakdowns. We worked to engineer our EPDM coolant hose material compound with superior electrochemical resistance, so your Gates® coolant hoses will last longer and keep your engine systems running stronger.
For a secure fit to virtually every vehicle on the road today, Gates® precision-manufactures our moulded engine hoses with exclusively-developed factory processes to ensure compatibility and exceptional performance to specific vehicle manufacturer specifications.
