Trucking Industry Fluid Analysis

Coolant Fluid Testing

The condition of a truck engine is largely determined by the cleanliness of the engine oil in the crankcase, however another critical characteristic for engine operation is associated with the engine coolant.  A significant number of truck engine failures are attributed to coolant system failures.  The continuous development heavy-duty diesel engines with high efficiency, high temperature and variable material cooling properties creates challenges for engine cooling systems.    

Testing coolants is an essential predictive maintenance program that works in tandem with condition monitoring programs to optimize reliability, reduce unscheduled downtime and avoid engine failure.   Regularly analyzing glycol will confirm potential need to replenish or replace coolant, determine if any contaminants have been introduced and assess the coolant protection for engine integrity.  

Clark’s coolant testing package includes several ASTM test methods for alkalinity, freeze point, and pH level.  We are typically test particle count to determine if there is any debris in the cooling system.   

Standard Test Packages Includes:

ASTM D5185 - ICP Spectroscopy

ASTM D4377 - Karl Fischer

ASTM D445 - Viscosity

ASTM  E2412 - FTIR

ASTM D664- Base Number

Fuel Testing

Diesel fuel testing is critical for ensuring quality control, specification validation and regulatory compliance. Diesel fuel or distillate oil testing can provide analysis of fuel quality by monitoring sulfur, trace metals, and biodiesel blends. Bulk storage of diesel fuel can sometimes compromise the integrity of fuel, Clark provides fuel sampling consultation and recommendations to ensure homogeneity and quality of the test sample.

Clark provides diesel fuel testing package in accordance with ASTM Standards. In addition to analyzing fuel quality, Clark’s diesel fuel test package provides analysis of cold weather conditions, containments and emission compliance. Our laboratory can also provide analysis of ultra-low sulfur diesel, fuel additives and biodiesel testing. 

Standard Diesel Fuel Packages Includes:

ASTM D445 - Viscosity

ASTM D93 - Flash Point

ASTM D2709 - Water and Sediment

ASTM D5453, D2622, D129 - Sulfur
