If your coolant level is low, it could lead to your enterprise vehicle malfunctioning. Let’s start by asking: what is coolant? It’s a fluid that transfers heat and regulates the temperature of the engine block and related parts. With the help of special additives, you’re protected in both extreme cold and heat conditions. Sprinter of Laguna Niguel will tell you how to check your coolant level as well as be your all-around Sprinter maintenance team.
You deserve to be able to get the job done without worrying about fleet maintenance; that’s why we have Sprinter van service financing and manufacturer-certified technicians.
You don’t have to open the radiator cap to check the level. Instead, check the markings on the side of the reservoir. If the liquid reaches the “full” marking line, you’re good to go. If it doesn’t, remove the radiator cap and add the coolant or a 50/50 mix of coolant/water. Read the bottle to see if it’s premixed. It’s also a good idea to also inspect the hoses connected to the radiator for any leaks or damage.
Note: If you’re adding more liquid to the cooling system, be sure the engine has cooled. Also, don’t attempt to open the radiator cap while the engine is hot.
Coolant is thinner than oil but thicker than water. If you notice a sludgy appearance to the liquid, schedule service ASAP. There’s a good chance your car has an internal gasket leak. Driving is possible, but a leaking gasket will drain the coolant quickly. This means the engine is at risk of overheating and being severely damaged.
Coolant levels deplete over time, so it’s a good idea to check up on the cooling system every three to six months. Usually, the liquid is blue, green, yellow, or red. If it’s brownish or even colorless, flush the system and replace the fluid.
