TRP® EXTENDED LIFE COOLANT

TRP® ELC is formulated with superior inhibitors, known as Organic Additive Technology (OAT), to minimize deposits that inhibit heat transfer, and corrosion that degrades important metal parts. Traditional coolants contain mineral/inorganic inhibitors, such as phosphate, borate, and silicate. These non-OAT coolants leave mineral salt deposits on radiator tubes, which create a thermal blanket that increases the risk of downtime due to engine overheating.

Importantly, not all coolants are the same. Conventional and heavy-duty coolant formulations require inhibitors, known as Supplemental Coolant Additives (SCAs). Without these inhibitors, overheating will occur leading to significant cooling system damage and potential engine failure. Another downside of these coolants is they must be changed every 200,000–300,000 miles/2–3 years, with testing and addition of SCAs between changes.

Verify coolant fluid ratios for freeze point by using a refractometer each time the truck is brought in for service.

The freeze point should be between -32°F to -37°F. The acceptable freeze point range is between -12°F to -60°F, but some fluid ratio correction may be needed if the freeze point falls near the limits of the acceptable range. If the freeze point falls outside of this range, the coolant should be replaced.

A large national fleet had been having Exhaust Gas Recirculation (EGR) cooler issues which were not being diagnosed early enough to address. At one point they were averaging 12 EGR cooler failures a month. After setting up a best-in-class preventive maintenance coolant test schedule they were able to reduce these from 12 to less than 1 per month, generating a large, ongoing, operations savings gain.

What does an EGR cooler failure cost when you factor in:

• Displaced driver?
• Payload not delivered?
• Towing to the dealer?
• EGR cooler replacement?

Those costs add up fast and can be several thousand dollars in costs per down truck. Additionally, there is the negative impact to customer service and reliability performance metrics when you cannot meet your commitments due to downtime.
