Camshaft Position Sensor Replacement

Your engine computer needs to know when it’s time to send a spark through the spark plug, it does this with the information from the camshaft position sensor. The CPS tells the engine computer the exact right time to ignite the air/fuel mixture and makes sure your engine runs as flawlessly as possible.

Accelerator Cable Replacement

A lot of cars used to trust a steel cable to transmit inputs to the accelerator to the engine. Modern cars use a drive-by-wire system. Over time the cable will need adjusting as it stretches. In some rare cases, if you’re a real fast and furious driver, it can snap and require replacing.

Harmonic Balancer Replacement

A harmonic balancer is not a musical instrument, it’s a very important engine component. It’s connected to the crankshaft, and is almost always found at the front of the engine. Its primary job is to reduce vibrations in your engine and ensure smooth running. However, as it runs off of the crankshaft it’s usually used as a pulley to run the belts that power vital components such as: power steering, radiator fans, air conditioning and alternators.

Fuel Hose Replacement

In order to get your fuel from your gas tank to your engine, it travels through a dedicated fuel hose. These hoses are a special make up and are designed to withstand the toxic nature of petrol or diesel. Over time, due to heat, wear and tear, or age, these hoses break down slowly.
