If you own a machine or piece of equipment with a Cat^® engine, you know how important it is to keep it in good shape and prevent any problems that could affect your performance and efficiency. This is especially true in the summer when higher temperatures and more demand can add extra stress to your machine’s engine. Check out our tips on maintaining your Cat engine in the summer heat so you can avoid unexpected downtime.

Why is engine maintenance essential?

Cat engines are designed to deliver reliable and consistent power for various applications, such as construction, mining, agriculture and more. They are also built to meet the strict emissions standards and regulations for different regions and industries. However, to make sure your engine performs at its best and complies with the emissions requirements, you should follow a regular preventative maintenance schedule and frequently check your engine components. This will help you:

Extend the lifespan of your engine and its parts
Reduce fuel consumption and operating costs
Prevent breakdowns and costly repairs
Enhance safety and performance
Protect the environment and your reputation

How to maintain your engines in the summer

Here are some of the critical steps you should take to preserve your Cat engine in the summer.

Check Your Cooling System Regularly

Your cooling system is vital for preventing overheating and engine damage. It’s made up of several components, including the coolant, hoses, belts, radiator and fan. You should check these components regularly and look for any signs of leaks, cracks, wear or corrosion that could affect the performance of your cooling system. If you need to top up your coolant, mix only the recommended type with distilled water. Never use tap water since it can cause scaling and corrosion.

Change Your Oil and Filter According to the Schedule

Oil is essential for lubricating and protecting engine components from friction and wear. It also helps to remove heat and contaminants from the engine. However, oil can degrade over time and lose its effectiveness. Change your oil and filter according to the manufacturer’s schedule or the Cat Electronic Service Tool (EST) recommendations. Use only the approved oil grade and viscosity for your engine model and operating conditions.

Inspect Your Air Filter and Intake System

Your air filter and intake system deliver clean air to your engine for combustion. Dirty or clogged air filters can reduce airflow and engine efficiency and increase fuel consumption and emissions. Inspect your air filter and intake system regularly and replace them when needed. Use only genuine Cat filters designed to fit your engine and provide the best filtration.

Avoid Unnecessary Idling

Idling your engine wastes fuel and increases emissions and can cause carbon buildup in your cylinders, valves and injectors. It can also affect your aftertreatment system, which needs high exhaust temperatures to function correctly. To avoid these problems, limit your idling time to the minimum necessary for warm-up, cool-down or operation. Use the Cat Auto Idle Shutdown feature on your engine to automatically shut off the engine after a preset idle time.

Don’t Overload Your Engine

Overloading your engine can cause excessive heat, stress and wear on your engine components. It can also reduce your fuel efficiency and increase your emissions. To prevent overloading, follow your engine model and application's rated power and torque specifications. Use your engine's Cat Power Management System (PMS) to enhance your power output and fuel consumption.

Don’t Ignore Warning Signs or Fault Codes

If you notice any unusual noises, smells, smoke or performance issues with your engine, don’t ignore them. They could be a sign of a severe problem that needs immediate attention. If you see any warning lights or fault codes on your instrument panel or Cat EST, don’t dismiss them. They could alert you to a potential malfunction or failure that could damage your engine or affect its emissions compliance. Talk to your Cat dealer or check your service manual for troubleshooting and repair guidance.

Following these tips, you can keep your Cat engines in peak condition during summer. Contact your local Cat dealer for more information on maintaining your Cat engines.
