![]() This gauge indicates the transmission’s temperature. Monitors the engine exhaust temperature and warns drivers of potential engine damage. Excessively high temps may lead to engine damage. If the coolant is too hot, you should pull over at the next safe location, let it cool down, and check the manual to verify normal temperatures (many heavy diesels have 195 thermostats in them). Average engine temps vary but are usually between 165-195 degrees Fahrenheit. Locate and familiarize yourself with all temperature gauges, including the: Some gauges require high temperatures, while others require low temps for best performance capabilities. Temperature gauges:Ī heavy-duty truck’s dash features multiple temperature gauges. If this happens, quickly pull over to a safe location before a breakdown or accident occurs. Pay attention to both the primary and secondary gauges - any pressure falling below 90 may indicate leaks or other issues in the air brake system. The air pressure gauge measures the PSI in each truck reservoir. Fuel gaugeĭrivers should regularly check the fuel gauge to make sure there’s plenty of diesel to reach the destination. Inadequate oil pressure can cause engine damage. ![]() This gauge monitors the truck’s oil pressure - normal oil pressure is between 30-70 pounds per square inch (PSI). Today’s diesel engines are designed for maximum peak torque at lower RPMs. The tachometer measures the engine’s speed in revolutions per minute (RPM). Watching where the needle lands can help drivers anticipate charging issues before they become major problems. The middle green area means normal battery charge, and the right-hand red area means it’s overcharged. With a colored volt gauge, if the needle hovers over the left-hand red area, it means the battery is undercharged. If the voltage constantly stays below 14 volts (under charged) or goes above 15 volts (over charged), you should have the system checked. Unless there is a heavy pull on the electrical system, it should stay within this range. With a numbered voltmeter, a fully charged battery will read 14 to 14.5 volts when the engine is running (and the charging system takes over). This dash gauge displays the battery charge status using numbers (12/14/16) or three colored sections. This information helps determine when a vehicle needs an oil change or other maintenance based on mileage. Most drivers are already familiar with the function of the odometer - it displays the total mileage on a truck and can also display mileage data for a specific route. Common truck gaugesĭashboard gauges display vital information and data to keep drivers aware of how the truck and its internal parts are functioning. Please refer to the vehicle’s operation manual to learn about controls specific to your truck. ![]() Note: The following gauges and warning lights are on all heavy-duty dashboards. ![]() To keep trucks in normal operating condition, drivers should understand the function of each panel control so they can detect and call in any complications. Should you pull over to fuel up and check out the problem or is it safe to continue driving? While some dashboard lights and instruments indicate emergency situations, others notify the driver of issues that could be concerning if they aren’t serviced soon. With a quick glance at the dashboard, you notice the fuel level is low, and the tire inflation light is on. Your next loading dock is 45 minutes away. What your dashboard gauges and warning lights are really indicating ![]()
