Over time, coolant hoses in your vehicle can deteriorate due to prolonged exposure to high temperatures from the coolant. Made of reinforced rubber, these hoses are prone to issues such as splitting at hose clamps, swelling, cracking, or even breaking, which can leave you stranded. It's important to replace them at the first sign of wear to prevent coolant loss and ensure your engine stays properly cooled.
