Engine Flush
Sludge deposits build up over time which affects engine performance and fuel economy. An Engine Flush is designed to remove this sludge helping your engine run freely and efficiently.

Power Steering Flush
The steering system contains many complex hydraulic components and therefore needs attention over time. A simple and regular Power Steering Flush is designed to remove foreign matter, helping components run freely to maintain optimum feel and accuracy while driving.

Transmission Service and Flush
Like your engine, the transmission is a vital and complex area that needs regular maintenance. Thankfully a transmission service and simple flush is often all that is needed to ensure smooth gear changes and longer life.

Fuel Injection
Fuel injectors are designed to provide the correct volume and pressure of fuel into the engine to maximise performance, economy and smooth running. Flat spots in acceleration, poor fuel economy or poor acceleration are a sign your fuel injectors need a service. A Fuel injection service is therefore routine and designed to keep your car running at peak condition.
