Professional Power Steering Flush

Dirty power steering fluid can cause increased steering effort and can be noisy.  Most importantly, extended system neglect can harden seals, cause leaking and force system replacement.  Use Professional Power Steering Flush to remove deposits and debris when changing the power steering fluid.

Professional Engine Flush

$129.95                    

Engine oil breakdown causes deposit build-up, reduced fuel efficiency, increased oil consumption and potentially engine failure.  This is a great cleaning alternative to flush machines as it flushes the engine twice.

• Removes more used oil than conventional drain
• Removes sludge & deposits that can lead to the breakdown of engine oil

Professional 3-Step Fuel System Cleaner

$129.95                    

A dirty fuel system reduces the performance you can get out of your engine.  Carbon deposits can build up in the fuel injectors, intake valves and combustion chambers.  Professionals recommend performing a 3-Step Fuel System Cleaning Service once a year or every 12,000 miles.

Step 1: Concentrated Air Intake Cleaner - Removes built-up deposits from the throttle plate (butterfly valve)

Step 2: Liquid Intake Cleaner - Cleans the intake system through the PCV line.  A drip/hose assembly is necessary for this step.

Step 3: Fuel System Cleaner - Add to the gas tank to clean-up fuel injector deposits

Professional Radiator Flush

$149.95

Given that 62% of all vehicles are 6+ years and that aging radiators can have scale build-up and minor system leaks, coolant system failure is a leading cause for breakdowns during highway driving.  Use Professional Radiator Flush when changing the radiator fluid to:

• Remove rust, scale and oily residue that can cause overheating and breakdown.
• Help maintain coolant flow

Professional Transmission Flush

$159.95                    

Most transmission failures occur because the transmission fluid is never changed.  High temperatures cause fluid deterioration, reduced lubricity and seal breakdown - ultimately resulting in leaks and system failure.  Use Professional Transmission Fluid when changing the transmission fluid to:

• Help clean the transmission
• Remove harmful sludge and varnish deposits
• Remover wear metals
