2017 Chevrolet Impala Hoses and Pipes

Why Hoses and Pipes Matter for Your Vehicle

Every engine depends on a network of hoses and pipes to move fluids, manage heat, and keep critical systems talking to one another. From the coolant coursing through your radiator hoses to the hot air routed through intake ducting, these components work quietly behind the scenes — until they don't. A single cracked or swollen hose can trigger overheating, loss of engine performance, or even catastrophic engine damage within minutes. Understanding what hoses do, and when to replace them, is one of the most important aspects of proactive vehicle maintenance.

What's in This Category

Hoses and pipes span a wide range of systems and applications. The most common replacement need falls under cooling — specifically radiator coolant hoses, which carry hot coolant away from the engine block and return cooled fluid from the radiator. Closely related are engine coolant hoses, which branch throughout the engine bay to regulate temperatures across different components. For drivers who want a single, comprehensive fix, radiator coolant hose kits bundle all the necessary hoses for a complete system refresh in one purchase.

Beyond basic cooling, hot air hoses play a vital role in turbocharged and naturally aspirated engines alike, directing warm air from the engine bay or charge air cooler back into the intake stream. Meanwhile, engine coolant bypass hoses allow coolant to circulate through alternative paths when the thermostat is closed, preventing localized hot spots during cold starts. Together, these subcategories cover the full spectrum of under-hood fluid and air management.

Signs It's Time to Replace Your Hoses

• Visible cracks, splits, or bulges in the hose wall
• Soft or spongy feel when squeezed — a sign of internal deterioration
• Coolant leaks or puddles underneath the vehicle
• Overheating or erratic temperature gauge behavior
• Age — most rubber hoses should be inspected every 4 years and replaced every 6–10 years regardless of appearance

Top Brands in Hoses and Pipes

Gates is one of the most trusted names in automotive hoses, with over a century of engineering experience. Founded in 1911, Gates has worked alongside virtually every major OEM worldwide, and their aftermarket hoses are engineered to meet or exceed original equipment specifications for heat, pressure, and corrosion resistance.

Motorcraft is Ford's factory parts brand, making their hoses the natural choice for Ford, Lincoln, and Mercury vehicle owners who want a guaranteed OEM fit and performance standard right out of the box.

Dorman has built a strong reputation in the aftermarket by engineering improved replacement hoses — often addressing known OEM shortcomings — and offering broad vehicle coverage across domestic, import, and light-truck applications.

ACDelco is General Motors' trusted parts division, supplying OE-quality hoses for GM vehicles while also offering a broad professional line covering non-GM applications. Their hoses are widely used by dealerships and independent shops alike.

Mishimoto takes a performance-first approach, crafting silicone hoses reinforced with heat-resistant embedded fibers that offer increased pressure and temperature tolerance compared to factory rubber hoses — and backing them with a signature Lifetime Warranty.

Choosing the Right Hose

When shopping for replacement hoses, always verify fitment by year, make, model, and engine size. Consider the material: standard EPDM rubber hoses offer reliable, cost-effective performance, while reinforced silicone hoses are a popular upgrade for high-performance or high-temperature applications. For cooling system work, replacing all hoses at once — rather than just the failed one — can save significant labor time and prevent a repeat breakdown in the near future.
