Timing Belt Blues

This was the tensioner spring for the timing belt on Amanda's new car. Look closely at the clip on the right. Scary, huh? That's crazy worn out. It's also stretched beyond spec: the spring coils should be touching each other.

With 90k miles, the timing belt had not yet been replaced on her new 2000 Protege ES*. This is a 100k mile service in California (with inspections every 30k); a 60k mile service everywhere else**. So it was due. In ordering the parts, I neglected to order a new tensioner spring. It's only $3. To get it locally, however, it costs $90, and you can only get it with the two pulleys. Circumstances being what they were, Amanda had to buy the $90 set.

Next time, I will know. And so will you, dear reader who happens to own a Mazda product with this type of spring tensioner, and happens to replace his/her own timing belts, and is expecting to do so soon.

You can get this spring at If you work at RockAuto, please send me free stuff. I need to fix a lot of stuff. Come on, what's a Miata steering rack between friends? We are friends, right? Right? ....


*Pedantic aside: that's the F-series 1.8L engine, the same family used in forthcoming Proteges; the 1.6L engine was a B-series, related to the Miata and Protege engines of previous years, and also the Ford Escort GT.

**I'm sure this has to do with California laws more than engineering.

  1. I'm glad I had to pay $90 for a spring, you jackwagon.
