What is a cooling system service?

Before any repairs, we always start with a cooling system diagnostic to help determine if you’re experiencing radiator problems, a failed thermostat, simply running low on engine coolant, or some other issue.

If you’re a step-by-step person, here’s what a full service typically includes:

• Inspecting the radiator, water pump, thermostat, heater core, control valve, head gasket, fans, belts, and hoses

• Checking for leaks, cracks, and worn elements

• Checking pressure conditions and coolant volume

• Flushing and disposing of used coolant fluid

• Installing any necessary replacement parts

• Refilling the system with fresh antifreeze coolant fluid

Signs you need a cooling system service

Heat is produced every time you drive, so if your cooling system isn’t doing its job, problems pile up fast. Look out for these signs:

• Overheating engine - If you’re stuck with steam rolling out from under the hood, chances are your coolant isn’t circulating properly.

• High temperature gauge - A gauge that consistently runs hot is a warning light you don’t want to ignore.

• Sweet maple syrup smell - Unless you’re running a breakfast diner out of your car, that smell means antifreeze is leaking and burning.

• Leaking fluid - Antifreeze is usually green or orange, but it can come in different colors. Any puddles under your vehicle should be checked out immediately.

Why is a cooling system service important?

Your vehicle’s engine generates enough heat to destroy itself every day. Sounds dramatic, but it’s true - and the cooling system is what prevents that from happening.

Antifreeze and coolant circulate through the engine to absorb heat and carry it away. This mixture keeps liquid from freezing in the winter and prevents overheating in the summer. Without it, you risk everything from blown gaskets to a complete engine failure.

How frequently should I get a cooling system service?

Your owner’s manual will give a mileage interval, but it varies a lot - anywhere from 30,000 miles to 120,000 miles depending on the vehicle. Antifreeze doesn’t “expire” the way milk does, but it does deteriorate over time.

If you notice overheating, a hot temperature gauge, or a coolant leak, don’t wait. Otherwise, stick to your maintenance schedule or ask us to test your coolant when you’re in for other services. Changing it on time is the easiest way to prevent costly engine damage.
