Crucially: It's essential that the coolant meets the specifications outlined in your owner's manual. The manual will specify the correct type (often a specific color) and the proper concentration (usually a mix of coolant and distilled water). Using the wrong coolant can severely damage your engine.
Look for coolant that is:
* Specifically designed for heavy-duty diesel engines: This is critical due to the higher operating temperatures and pressures compared to gasoline engines.
* Contains corrosion inhibitors: These are essential for protecting the various metals in your engine's cooling system.
* Meets the recommended specifications: Consult your owner's manual for the correct specifications; it may specify a particular brand or type.
In short: Check your owner's manual. That's the definitive source of information for your vehicle's coolant requirements. Don't rely solely on general advice – using the incorrect coolant could be very costly.
