Proactive maintenance is well proven as a major way to reduce wear and tear on your car and prevent major problems. Businesses that own Fleets of vehicles have studied and continue to study and update there maintenance procedures because it saves them money.

A leak in an Oil Cooler hose can only leak more if left alone and member have reported that their hose/s gave out and some unexpected time on the road.

I also lost some threads off of my Oil Cooler when I was going to change the hoses; but it was much better to deal with it in my driveway than on the road somewhere. I am not sorry that I changed the hoses (in my case I decided to change only the hose itself not the whole hose assembly) as it was going to need to be done anyway and the threads were going to strip if I did it later anyway.

The good news is that if you take sometime and search and read through a bunch of Threads on the job you are about to do before you start the job you can plan for some of the problems and plan more time to deal with them.

In the past I earned my living as a Mechanic and even with a bunch of tools, training and technical resources available jobs can still go sour.
