Disadvantages of the Mazda CA-DE engine
- A known weakness of Cyclone motors is the short-lived water pump.
- It can leak even on short runs and then the antifreeze will get into the lubricant.
- The pump here is rotated by the timing chain and its wedge can lead to expensive repairs.
- And in all other respects, this is a reliable power unit with a resource of more than 300 thousand km.
- But it’s better not to save on fuel quality, otherwise the catalyst will not last long.
