Your semi-truck’s cooling system is crucial in helping the truck’s engine work as efficiently and smoothly as possible. Although charge air coolers are designed and built for hard work under extreme temperatures, they tend to lose their efficacy over time, so you should test them from time to time. This article covers many other reasons to test your charge air cooler (CAC) in your semi-truck.
Top Reasons To Test Your Semi-Truck’s Charge Air Cooler
Efficiency
The CAC is responsible for cooling the compressed air from the turbocharger before it enters the engine. If the CAC is leaking, the compressed air will be warmer and at a lower pressure, which can lead to a decrease in engine efficiency and an increase in fuel consumption.
Engine Damage
If the CAC is not functioning properly, it can cause elevated coolant temperatures, elevated soot levels in your oil, and premature piston, ring, and valve failure, which can lead to serious engine damage.
Reduced Power
A leaking or malfunctioning CAC can reduce the power of the engine due to incomplete fuel burn in the cylinders, resulting in poor performance and reduced ability to pull heavy loads.
Emissions
A malfunctioning CAC can also affect engine emissions, increasing soot and clogging your DPF creating increased regen cycles and maintenance.
Cost savings
By regularly testing and maintaining the CAC, you can ensure that it is functioning correctly and avoid costly repairs and downtime in the future.
Improved longevity of the engine
A well-maintained CAC will help prolong the engine’s life by preventing damage caused by elevated coolant temperatures.
Your truck’s charge air cooler helps maintain the engine’s functional performance, durability, and fuel efficiency. However, it can only do so when it is in the best working condition. Regularly testing the CAC and identifying any issues early on will help to ensure the efficient operation of the engine, prevent costly repairs, and extend the life of the semi-truck.
