Can an automotive hose detach during use?
Yes, make sure the hose clamps are screwed on tightly when installing.

Can an automotive hose freeze in the winter?
Yes – when there’s water in the hose. That’s why it’s important to follow the vehicle manufacturer’s recommendation on the use of engine coolant.

Can I use the same automotive hose for multiple uses?
No, use the hose in the way it’s listed in the ACDelco belts and hoses catalog.

Will I know when it is time to replace an automotive hose?
Yes, this requires inspection, though. When the engine is cool, squeeze the hoses with your thumb and forefinger near the clamps. Feel for soft or mushy spots. A good hose will have a firm yet pliant feel. Also, Inspect for cracks, nicks, bulges (usually while hot), or a collapsed section in the hose and oil contamination, or fraying near the connection points.

Are there steps I can take to ensure a longer automotive hose life?


• Examine hoses every 12 months. Look for leaks, cracks, or rot. Replace when showing signs of wear.

• Tighten any loose clamps. Replace clamps when replacing hoses.

• Have cooling system inspected immediately if instrument panel-mounted temperature gauge indicates engine overheating.

• Periodically remove bugs, leaves, and other debris from the front of the radiator. They can block airflow and substantially reduce cooling efficiency.

• Though electrochemical degradation occurs from the inside out, you can feel for voids, cracks, or weak spots. Squeeze the hose with your thumb and two or three fingers. If you’re not sure, remove the hose and check it visually.
