DON’T BE LEFT OUT IN THE COLD – PREPARE YOUR FLEET FOR WINTER

CASTROL LABCHECK / Post date: 1 November 2017

With colder temperatures just around the corner, it’s time to start preparing your fleet equipment for what is typically the harshest season of the year… winter.


No matter what the segment… transportation, refuse, aggregates, or construction…fleet downtime almost always results in a loss of revenue, which can take a huge bite out of your bottom line. But it doesn’t have to… many cold-weather issues that can impact your fleet can be avoided with regular coolant testing and analysis.


A significant cold-weather concern for fleet managers is maintaining adequate freeze protection. The chart featured on this page shows the freeze protection for ethylene and propylene glycol concentrations. It is important to maintain this freeze protection throughout the winter season, which can be achieved by testing the glycol level with a refractometer during every preventative maintenance event.


Monitoring glycol levels in the field is the first proactive step to ensuring proper cooling system health. However, while freeze point must be monitored, boil point should also be a concern. Heat is the number one enemy of today’s modern engines. Operating temperatures are at their highest in the most-recent Tier 4 designs with an abundance of heat-producing components under the hood. This places even more demand on the cooling system to transfer heat sufficiently enough to maximize engine efficiency and fluid life.

To sufficiently winterize your fleet against extreme seasonal temperatures, be sure to analyze your coolants. Test for contaminants that can cause scale or acid formation, glycol degradation, signs of air leaks, hot spots, and localized overheating. Monitor inhibitor levels for proper metal protection and determine if the coolant’s pH is within specifications.


The Castrol® Labcheck® program offers several different coolant test packages to meet your needs. Please contact your Castrol sales or field engineering representative for assistance.


By taking these recommended steps, the next time you’re left out in the cold… you’ll be ready!
