Installation Notes

Confirm engine and timing belt configuration before ordering. On the listed applications, the timing belt must be replaced when servicing the water pump, and some fitments include date-specific coverage for 2011 Mazda CX-9 and 2011 Mazda 6. Dayco DP858 is used in timing belt-driven cooling systems, so proper belt timing and coolant refill procedures are important during installation.
