Coolant is vital for the engine of any vehicle. While operating, engines get extremely hot and rely on coolant to stay cool. Even your rental trucks can overheat if the coolant is low or empty.
If one of your drivers is reporting overheating, you should check the truck’s coolant immediately. It’s likely that the truck has a leak. In most cases you’ll have to get the truck to a mechanic.
However, you’ll need to get it there in one piece. This means you’ll have to refill the coolant in order to get the truck to the mechanic. These steps will help you make a safe transit to the mechanic.
