Introduction 

 

Congratulations on your selection of the 

CARBONCLEAN DUAL SYSTEM. 

  By choosing this 

product, you are acquiring the most technologically advanced method available for cleaning 
harmful fuel system contaminants from gasoline engines. 
 
The 

MCS 352

 

is a self-contained cleaning system, designed to connect to any gasoline or 

diesel engine (up to 7.3L).  Once the unit

 

is connected, it temporarily replaces the regular 

fuel supply with a mixture of fuel and the specially formulated 

CarbonClean Cleaning 

Detergent.

 

 
With the engine idling, the unit

 

pumps the fuel/detergent mixture through the engine's fuel 

system.  As the mixture passes through the vehicles’ fuel system, it loosens and dissolves 
accumulated deposits, which then pass harmlessly out through the exhaust system or are 
removed by the unit’s

 

fuel filter. Removing contaminants from the combustion chamber 

creates a more even burn of fuel, which improves horsepower, increases fuel economy, and 
reduces exhaust emissions. 
 
Please refer to the chart below for the recommended service intervals:

Please study this 

User Guide

 to become thoroughly familiar with the 

MCS 352

 before using it.  

 

 

IMPORTANT

 

 

The MCS 352 Fuel System Machines are designed to work  

EXCLUSIVELY

  

with CarbonClean Cleaning Detergents.   

 

Use of any other chemicals during this process may cause operational failure 

of the MCS 352 and voids the manufacturer’s warranty.  

See warranty card for details.
