Periodic maintenance

Items that don't need doing at every service but should be on your radar at the right mileage or age.

Service item	Interval	Typical cost
Coolant flush Manufacturer interval 60,000 miles. Specialists recommend 36,000 miles for K-Series engines due to head gasket sensitivity. Use OAT coolant only. Flush prevents liner drop and head gasket failure. ZR	60,000 miles or 5 years	£65–£95
Brake fluid Manufacturer interval 2 years regardless of mileage. Use DOT 4 brake fluid. Old fluid causes brake hose ferrule corrosion which is a documented MOT failure point on this model. ZR	2 years	£35–£55
Spark plugs Manufacturer interval 12,000 miles for K-Series engines. Use NGK or Champion plugs to manufacturer specification. Worn plugs cause emissions test failures. ZR	12,000 miles or 1 year	£35–£55
