Annual Coolant System Maintenance Helps Reduce Engine Failures

So you are checking your equipment’s coolant system on a regular basis when it comes in for maintenance. Are you also conducting deeper system diagnostics once a year?

While these tests are more intensive than the regular system checks, they provide more comprehensive insight into your coolant system’s health. Annually, you should:

  1. Take a coolant sample and send it to an approved Lubewatch lab (or other oil analysis program) for testing.
  2. Perform a cooling system pressure test.
  3. Track all of your results over time. If you start noticing deterioration, change your coolant.

You should also implement systems in your shop to make sure that you’re servicing engines promptly and correctly. Here are some things you can do:

  1. Place labels in all of the vehicles in your fleet identifying the type of coolant in their system. (Chevron’s Smartfill labels are a good option.)
  2. Determine how often your cooling system and coolant need to be checked, in accordance with OEM recommendations.
  3. Ensure that you are storing your coolant appropriately given your level of use. If you mix coolant with water on site, make sure the water meets OEM and coolant manufacturer requirements.

Proactively monitoring and maintaining your coolant systems will help to reduce the chance of diesel engine failure, and will save you maintenance and downtime costs. Chevron has developed a coolant maintenance kit named Kool Tools to help you develop your own best-in-class program. Contact us to find out how you can get one.
