What Are You Looking For?
Manufacturers typically recommend replacing hoses every four years, but this timeframe can vary based on factors such as mileage and weather conditions. A vehicle that is driven more frequently will likely require hose replacement sooner than one that is used less often. Here are four common indicators that your hoses may need replacing, easily identifiable during a quick inspection:
Kinks: Hoses may kink due to improper handling or age-related rigidity. Kinks can lead to cracks, leaks, and impeded fluid flow, potentially causing the hose to fail catastrophically. If a hose is kinked, it's important to inspect it for additional damage, such as cracking, and consider replacing it if necessary.
Stiff or Brittle Texture: Overheating can cause hoses to become stiff and brittle over time. This loss of flexibility increases the likelihood of cracking, weakening the hose and risking leaks or bursts. Once a hose becomes hard and brittle, it's essential to replace it as leaving it in place could result in further damage.
Surface Cracks: Heat exposure and repeated heating and cooling cycles can cause hoses to lose elasticity, leading to surface cracks. Driving with cracked hoses is hazardous and can result in engine damage or failure. While cracked hoses can be temporarily reinforced with duct tape to reach a mechanic for professional replacement, it's crucial to address this issue promptly.
Bulges or Bubbles: Swollen hoses may indicate excessive pressure, internal wear, exposure to high heat, or kinks causing fluid backup. A swollen hose is at risk of bursting and should be replaced immediately to prevent potential accidents or engine damage.
A blown hose cannot be salvaged and poses a high risk of bursting, necessitating immediate replacement. While hoses can sometimes last longer than recommended by manufacturers, it's best practice to replace them at the first sign of trouble to prevent engine damage. Consider upgrading to silicone hoses for improved durability and performance.
