This hose basically moves coolant – that’s the stuff that keeps your engine from overheating – between different parts of the cooling system. Typically it connects the radiator to the engine, or the water pump to the heater core, things like that. It’s a pretty simple part, really, just a reinforced rubber tube designed to handle heat and pressure. Think of it like the arteries in your body. The coolant needs a pathway to circulate and regulate temperature. This hose is a crucial part of that pathway. It allows the coolant to travel from the engine where it picks up heat, to the radiator where it sheds that heat, and then back again. There are usually several of these hoses in a vehicle, each with a specific job in the overall cooling loop. If this hose fails, you’re going to have a problem, a potentially big one. A leak can cause coolant to spill out, leading to overheating. Overheating can quickly cause serious engine damage, like a cracked head or warped block. It acts like a shield protecting your engine. You’ll notice if one goes bad, usually by seeing coolant under your car or a temperature gauge climbing higher than normal. It’s not something you want to put off fixing. We carry a good selection of these, and you can find them easily on Fixparts Online if you prefer to look yourself. Replacing a failing hose is a relatively inexpensive repair that can save you from a very costly engine rebuild.
