Description

This water hose is a critical component of the engine cooling system, responsible for circulating coolant to prevent overheating.

This hose is constructed to withstand the high temperatures and pressures of modern engines, ensuring reliable and long-lasting performance. Its dimensions are standard size for its application.

Key Features & Benefits

This hose carries coolant – that’s a mix of water and antifreeze – between your engine and the radiator. Basically, it moves the fluid that keeps your engine from overheating. There are usually several of these hoses, connecting different parts of the cooling system. They’re pretty simple in design – durable rubber designed to withstand heat and pressure. Think of it like the arteries and veins in your body. Your engine makes heat when it runs, and the coolant flowing through this hose is what carries that heat away to the radiator, which then cools it down. The cooled coolant then cycles back to the engine. It’s a continuous loop, and the water hose is a vital part of it. Different hoses handle different parts of that cycle; some go to the radiator, some connect the engine block to the water pump, and so on.

Symptoms, Risks & Replacements

If this hose fails—if it cracks, gets brittle, or develops a leak—your engine can overheat fast. Overheating can cause some serious damage. Think blown head gaskets, warped cylinder heads…really expensive repairs. You’ll notice if a hose is going bad usually; you might see coolant leaking, or you might see some crusty residue around the hose. Sometimes, you won’t see a leak right away, but the hose itself will get soft and spongy when you squeeze it. They're relatively inexpensive to replace, which makes preventative maintenance a good idea. We carry a good selection here, and you can also find them easily enough online at places like Fixparts Online if you prefer to look around. It's one of those parts you really don’t want to ignore.
