What Causes a Check Engine Light to Come On?

The check engine light can illuminate for several reasons, ranging from minor to serious issues. Common causes include faulty oxygen sensors, exhaust gas recirculation (EGR) system problems, or malfunctioning fuel injectors. Other possibilities include turbocharger issues or electrical system faults.

Ignoring this warning can reduce fuel efficiency, breach emissions regulations (and get fined), and even cause catastrophic engine damage. This is why it’s essential to have your truck inspected as soon as possible.

How Do I Know if My Refrigeration Unit is Failing?

Here are some signs your refrigeration unit may be failing:

Inconsistent Temperatures: If the cooling is uneven or fluctuating, there may be an issue with the thermostat, compressor, or refrigerant levels.

Unusual Noises: Strange sounds, such as knocking, hissing, or clicking, can indicate mechanical problems within the unit.

Increased Fuel Consumption: If your unit is drawing more fuel than usual, it may be overworking due to a fault in the cooling system.

Ice Buildup: Excessive ice can signal poor airflow or a problem with the defrost cycle, affecting cooling efficiency.

Leaking Refrigerant: Visible leaks mean reduced efficiency and need immediate attention to avoid further damage.

How Often Should I Have My Brakes Inspected?

Regular brake inspections are crucial for ensuring your truck can stop safely, especially when carrying heavy loads. We recommend having your brakes checked every 12,000 miles or during routine maintenance. Regular inspections help identify issues like worn brake pads, air leaks, and imbalanced braking that can lead to unsafe driving conditions if not addressed promptly.
