Product Details
Gates 51390 is a molded radiator coolant hose made for lower cooling-system service on the 2013-2015 Acura RDX. The molded profile and matched end diameters help it follow the original hose path, while the EPDM material is suited for coolant exposure in everyday engine operation. If you are replacing a worn Acura RDX lower coolant hose, this part number 51390 provides an OE-style replacement option for the specified application.
The Gates Molded Coolant Hose product line covers a wide range of coolant hose applications, including upper, lower, bypass, and heater hose routing. That makes it a practical choice when you need a replacement hose that follows factory-style bends and dimensions rather than a universal straight hose.
Common Problems This Hose Can Address
- Coolant leaks from a cracked or aged lower radiator hose
- Softening, swelling, or collapse of the original hose
- Improper hose routing after a failed replacement
- Cooling-system service on a 2013-2015 Acura RDX lower hose connection
- Loss of factory-style fit from a worn molded hose
Installation Notes and Tips
Inspect hose clamps, mating necks, and nearby cooling components before installation. Drain coolant to a safe level, compare the molded shape and end diameters to the removed hose, and verify the hose is routed without twists or contact points. After installation, refill and bleed the cooling system according to the vehicle service procedure and check for leaks at operating temperature.
