Common Radiator Hose Problems

When was the last time that your hood to your car was opened and you checked your radiator hoses? Very recently, I hope. If not, this needs to be done real soon, unless you enjoy being stranded out in the middle of no-where. Steam spewing from under the hood is not a happy sight. Many hose problems are caused by high heat temperatures under the vehicle's hood. How can this be prevented?

All automotive hoses should be checked at least once every six months to be certain that they are operating properly. The best rule is to replace coolant hoses whenever you change the coolant/anti-freeze. (What? I need to change the coolant?) Yes, this should be done roughly every two years. This includes changing the heater hoses. Now, let's check out the hoses.

First, let's check both the upper and lower radiator hoses for cracks (which is characteristic of either heat or ozone damage). Cracks in the cover of the hose are not always considered heat damage. If the hose has cracks, but is still soft and not hardened, the problem could be due to ozone, found in heavy air pollution areas.

Next, the worst enemy of automotive hose is oil. This can come from the engine, power steering, brake system or various lubrication lines. Any of these fluids will cause the hose to swell and become soft and gooey. Some hoses could even have bubbles or bulges.

Another source of hose damage is abrasion, scuffing or gouging. This could be caused by the hose either encountering road debris (rocks, sticks, etc.), rubbing up against a bracket or other metal surface, or belt gouging.

To check coolant hoses, with the engine cool, feel the hoses immediately after starting the engine. The hoses should become pressurized and hot within minutes. If not, there is a problem with the cooling system.

These are all normal maintenance checks that should be done religiously to prevent any damage to your vehicle. It's just like getting a check-up from your doctor. The more you maintain your vehicle, the more it will perform for you.
