PRODUCT DESCRIPTION

01

Premium Material Construction

Crafted from high-quality EPDM (Ethylene Propylene Diene Monomer) rubber, this hose exhibits excellent resistance to a wide range of temperatures, from -30°C to +120°C, which are typical in an engine's operating environment. The EPDM material also provides remarkable resistance to ozone, UV rays, and common automotive chemicals, such as antifreeze and rust inhibitors. Additionally, it is reinforced with a layer of polyester fabric, enhancing its strength and durability, and enabling it to withstand the high pressures generated within the cooling system.

02

Precise Dimensions and Shape

The hose comes with precisely engineered dimensions and a specific shape that is optimized for the Dongfeng GX's engine layout. It has a smooth inner diameter that allows for efficient water flow, minimizing resistance and ensuring a consistent supply of coolant to the engine. The carefully designed bends and contours of the hose facilitate easy installation and proper routing within the engine compartment, without any kinks or sharp turns that could impede the flow of water.

03

Exceptional Durability

Thanks to its robust construction and high-quality materials, this engine water inlet rubber hose is built to last. It can endure continuous exposure to engine vibrations, thermal cycling, and the corrosive effects of the coolant mixture. The combination of EPDM rubber and polyester reinforcement provides high tensile strength, good elongation at break, and excellent tear resistance, reducing the risk of leaks, cracks, or premature failure. This long-term durability helps to minimize maintenance and replacement costs over the vehicle's lifespan.

04

Easy Installation

Designed with installation convenience in mind, the Dongfeng GX Engine Water Inlet Rubber Hose 1303021-H12B0 features standard fittings and connection points that are compatible with the existing hardware on the vehicle. It can be quickly and easily installed by professional mechanics or even DIY enthusiasts using common hand tools. The clear installation instructions provided ensure a hassle-free installation process, reducing the time required for maintenance or replacement work and getting the vehicle back on the road in no time.
