Question: When to replace timing belt?

Hi, I took my 2002 Mazda Protege 5 to a local independent auto repair facility to be serviced for a long road trip and among the items they mentioned may need to be addressed was the timing belt. The car only has 50,000 miles on it but it is slightly over 8 years old. Does the age of the timing belt matter or is it strictly the number of miles? Should I wait till it has 100,000 miles as recommended in the owners manual or replace it as recommended by the auto repair facility? Thanks!

The timing belt and it's associated components (water pump, belt tesioners, idler pulleys etc) are generally good for 7 years or 100k miles on your vehicle. After that time, they may fail or start leaking etc. This isn't a common occurrence but it does happen. Recently I replaced a timing belt group on a 2002 Audi with only 56k, the water pump had started leaking due to age.

You'll probably be okay for a bit longer, but to play it safe, plan on having the timing group service done with in the next year.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
