Disadvantages of the Mazda CY-DE engine
The short-lived water pump is the primary issue with all Cyclone engines.
It may leak even during brief runs, allowing the antifreeze to seep into the lubricant.
Additionally, the timing chain rotates the pump, and its wedge typically necessitates costly repairs.
Other than that, this power unit has a resource of over 300,000 kilometers and is totally dependable.
Lambda probes and a catalyst burn from it, so it cannot withstand poor fuel.
