My friend's car started overheating and losing coolant so I decided rather than letting the same thing happen to me I would look into having the timing belt and waterpump job done probably this summer. During my research I found a fellow Miata owner who put together some good videos on different parts of the job. Haven't done it yet, but they look like they'll be a big help!
