I replaced both of mine on my 115 300d for $20 and it was not a big job. It wasn't clean or fun but it didn't take long and now I don't have to worry about them blowing out of some lonely stretch of S. Texas road a 3 in the am. The question is, what am I doing on a lonely stretch of S. Texas road at 3 in the am?

Take the hoses off. Be careful with the nuts to the radiator connection. The radiator is aluminum and is the nuts are stuck you can twist off the male end at the radiator.

Remember in which direction the fittings are mounted on the hoses. If they are wrong by more than a few degrees it will be difficult to remount them.

Grind off the metal band that crimps the hoses to the fitting. Be careful not to grind into the fitting.

Take your fittings and hoses to a parts shop or hydraulic shop where they make hoses and have new ones made up. Remember about getting the fittings in the same position as the originals. The new hoses will have one layer of steel braiding and they are very difficult to twist.
