How to Check Coolant Levels

Oakville and Milton drivers frequently ask our Mercedes-Benz Burlington mechanics, “what is coolant?” Coolant is a liquid that helps to transfer heat across your engine block and regulates your engine’s temperature so that it doesn’t overheat. Too much heat can cause catastrophic engine failure, so it’s crucial that you’re regularly replenishing your coolant.  If you’re unsure of how to check your coolant level and top off your reservoir, read our guide. If you come up against any obstacles, don’t hesitate to take your vehicle into a centre. Our service specials make this maintenance very affordable.

What to Look for

Open the hood of your car. The reservoir for your coolant is on your radiator. It should be labelled, but if it isn’t, consult the owner’s manual for your vehicle in order to locate it. Check the markings along the side. If it is below the “full” line, then you should remove your radiator cap and fill it up with a mixture that is 50% coolant and 50% water. That said, many coolants are premixed with water, so be sure to double-check.

While you’re under the hood, Mississauga and Hamilton drivers should inspect the hoses extending from the radiator to ensure that there aren’t any leaks. Now that you have answers to the question, “what is coolant?” and know how to check your coolant levels, let’s take a look at the signs that you should take your vehicle into our garage.

When to See a Service Technician

In terms of consistency, your coolant should be thinner than oil and thicker than water. If your coolant appears “mucky” or “sludgy,” take your car in immediately. This indicates a probable leak in a gasket. If all of your coolant leaks out, your engine will overheat, in which case, you can expect to buy a new car—not to mention, it isn’t safe to drive when you’re at risk of catastrophic engine failure.
