How to save money on repairs

[Guest987]

I just read an article posted on how to save thousand of dollars in car repairs. The number one mentioned was to change the coolant by the book! I thought that was pretty interesting, because it can often be overlooked. It is kind of the key I would think on keeping the engine clean and operating in the desired temperature range. Expense wise to do it is not out-of-range really. What do you think?
