Q: How to determine a car hose problem

asked by on

How do I know if there is an issue with a hose on my car?

If you are referring to a coolant hose the answer is simple. I would recommend having a certified technician perform a cooling system pressure test on your vehicle. This test pressurizes the cooling system with the engine off in order to help the technician find leaks in the cooling system. Other problems that rubber hoses can have is getting too soft or too hard. Hoses that are too soft will eventually get pinhole(s) because the hose can no longer support the pressure inside the system. Hoses that are too hard become brittle and start to crack. This can also lead to leaks. Other than a pressure test, finding problems in cooling system hoses is as easy as giving them a squeeze. You should feel resistance but still be able to flatten the hose with your hand by 10%-25% on a hot cooling system.
