25 or 30 years ago, changing coolant hoses on an annual basis was not a bad idea. The hoses that we have today, however, are VERY long lived. I don't know exactly what material they are now made of unless it is kryptonite.

These hoses will last years and years and years. That said, I still inspect them VERY closely on a regular basis. Look closely around the edge of the clamps. Also if they stop looking shiny, then I replace them.

Since when they do fail, it is almost always along the end at the edge of the clamp, they are very easy to repair well enough to get you home. Simply take off the clamp, trim off the end of the hose and stick it back in place and retighten the clamp. After that DON'T FORGET TO GET A NEW ONE!

As an earlier poster said, "if it ain't broke, don't fix it." If, on the other hand, you are one who uses a topsider and never gets under the car to inspect things, then replacing them every few years might not be a bad idea.

Have a great day,
