Coolant ImageEngine Coolant Reference Guide
by Shelly Eckert, Account Manager
Atlanta, Georgia

Engine coolant technology has greatly changed over the years. These changes have not only improved heat transfer properties but also provided specific chemistry for requirements from engine manufacturers. Gone are the days of mixing coolant blindly; in are the days of knowing what you have and properly monitoring and maintaining your engine coolant to optimize the cooling system performance. 

With the variety of coolant formulas on the market today, your first step is to define the coolant you have and acquire the baseline information to begin monitoring your cooling system and defining the proper testing protocols. The second step is to plan your maintenance routine and monitor your cooling system.    

There are indeed a variety of core tests that are recommended for general coolant analysis. However, once you determine if you are using conventional, hybrid, or extended life coolant, the testing is specific to properly monitor that particular coolant. To assist you in understanding the variety of tests available, we offer an Engine Coolant Reference Guide for your use.  If you have any questions or want to discuss your coolant testing, please contact your local laboratory.


Environmental ImageALS Environmental Aids in Gulf Oil Spill Cleanup
by Joe Credeur, Laboratory Manager
ALS Environmental, Houston, Texas

On April 30, 2010, the Deepwater Horizon drilling rig in offshore waters south of New Orleans, Louisiana, exploded, causing one of the world's largest oil spills. The disaster has impacted the shores of Louisiana, Mississippi, Alabama, and Florida, along with the lives of thousands of Gulf Coast residents.

Following the oil spill, ALS Environmental was awarded a contract to perform testing for the United States Environmental Protection Agency (EPA). The contract includes analytical services in Region IV (Mississippi, Alabama, and Florida) through Tetra Tech, the consultant for the EPA and a valued client of ALS. More . . . .


Fuel ImageNew Automated CFPP Instrument Now Used at ALS Tribology's Sparks, Nevada, Laboratory
by Ambrose Hughey, OMA I, Laboratory Manager
Sparks, Nevada, and Portland, Oregon

ALS Tribology expands its fuel testing services with the addition of a new, automated cold filter plugging point (CFPP) instrument at our Sparks, Nevada, laboratory. The recently purchased instrument uses rapid cooling conditions during which 20 milliliters of fuel is drawn through a 45-micron screen and then is allowed to flow back through the screen again for further cooling. This process is continued every 1°C until either the 20 milliliters of fuel fails to be drawn through the screen (plugs the filter) in 60 seconds or it fails to return through the screen in 60 seconds.

The CFPP provides an indication of the low temperature operability of fuel. Low temperature operability is an issue with middle distillate fuels because they contain straight and branched chain hydrocarbons (paraffin waxes) that precipitate, causing wax formation at cooler temperatures. Wax formation can also be exacerbated by blends of biodiesel fuel with conventional diesel fuel. Wax may plug the fuel filter or completely gel the fuel, making it impossible for the fuel system to deliver fuel to the engine. More . . . .
