I just in the throws of replacing the cam belt on my motorhome it is 5 years old. Most people replace the water pump at the same time, i am led to believe this is the right thing to do. Having read an article in the Feb issue (2020) of the MMM magazine which states that there is no need to replace the water pump unless there is damage or a leak to it. The article suggests that the water pump should probably last the life of the engine. I am totally confused.
