- 2014 CX-5 Touring
I pulled off the engine cover of our 2014 CX5 a couple weeks ago while I was draining the ATF, and noticed some pretty significant leaking around the valve cover (or maybe the oil control valve, or maybe both). With 113,000 miles I'm thinking it's time I did some tune-up maintenance on the car, since I've done basically nothing in the engine bay since we purchased the car at 52K miles. This is what I've got in mind:
What about the coils? This is my first COP engine, so I'm not that familiar with having a coil on every plug. Are those usually a "replace when failed" type of thing, or just replace them all at a certain time to prevent a failure?
- Replace valve cover gasket and oil control valve gasket.
- Replace serpentine belt and the hydraulic tensioner
- Replace spark plugs (suggestions, NGK Iridium or something else?)
- Drain and refill coolant (Mazda FL22 preferred, or maybe the Ravenol FL22 concentrate I saw mentioned on BITOG?) https://www.amazon.com/dp/B00SFG4H64/?tag=m20b7-20
