Engine Cooling System Purpose

Your engine is liquid-cooled for a very important reason. As the engine burns fuel, only about one-third of the heat generated is converted to mechanical energy to drive the vehicle forward. Approximately one-third goes directly out of the exhaust system and is wasted to the atmosphere. The final third heats internal engine parts like the cylinder head, pistons, valves, and engine block. The heat absorbed by the engine components must be removed so that internals never reach temperatures high enough to reduce the strength of the materials, aluminum, steel, etc., of which they are made. There is a water jacket surrounding the cylinders in the cylinder block and coolant galleries cast into the heads themselves. As coolant is circulated around the cylinders and through the engine block, heat is transferred to the relatively cooler liquid. The liquid is then pumped to the radiator, where surrounding air is constantly passed across the radiator coolant tubes. The hotter coolant fluid gives up its heat to the air surrounding the car. Even during the hottest drives across the desert in the midst of summer, the temperature difference between the coolant inside the radiator at above 200° and the ambient air at 120° temperatures will still transfer heat in order to keep the engine at a safe operating temperature.

Engine Cooling System Failure Modes

Your engine’s cooling system is one of the most important yet fragile systems in your car. Why? Your cooling system has many points from which coolant may leak. It contains several rubber hoses that can crack and split or leak near a hose clamp connection. A water pump seal on every water pump in service will eventually leak. The radiator has plastic side tanks, which are subject to cracking and leakage after a few thousand heat cycles. The radiator also has several hundred feet of aluminum cooling tubes, all subject to leaks from road debris, impact, careless mechanics, etc. 

When the engine is running, the water pump maintains pressure in the engine’s cooling jacket so a potential leak will drain the engine of coolant steadily. However, not all the coolant needs to escape before damage can occur. The cylinder heads are at the top of most engines. These are the hottest parts of the engine because this is where fuel is burned to develop engine power. Once the water level has dropped enough to leave the cylinder head without coolant circulation, the head quickly warps, allowing coolant to exit the cooling jacket, past the head gasket, through the cylinders and out the engine exhaust or into the crankcase to mix with the oil.

This type of failure is called a “blown head gasket” and is a common and expensive problem. Most drivers don’t check the coolant recovery tank level or ever look at the engine coolant temperature gauge. Usually, a driver’s first indication of a problem is a check engine light or an engine that stops running.

Don’t wait until you have an expensive head gasket repair problem. ASR offers a service that can give you peace of mind while driving long distances in hot weather. Have a cooling system test done at ASR twice per year. We will check the coolant level and perform a pressure test of the cooling system to find potential leaks before they develop into interrupted business trips, vacations, and worse, expensive repairs.

Signs Your Cooling System Needs Attention

Ignoring cooling system problems can lead to engine failure and expensive repairs. Your vehicle will usually show warning signs when the cooling system isn't functioning properly. Here's what to watch for:

• Temperature gauge reading higher than normal
• Coolant puddles under your vehicle
• Sweet smell coming from the engine compartment
• Steam rising from under the hood
• Dashboard warning lights illuminating
• Heater not producing warm air
• Visible corrosion on radiator or hoses

Catching problems early can save you from major engine damage and costly repairs down the road.

Why Your Vehicle Needs Cooling System Maintenance

The cooling system protects your engine's overall health and performance. As coolant circulates through the water jacket and engine block, it absorbs tremendous heat from combustion. Without proper cooling, cylinder heads, pistons, and valves would quickly fail. Regular maintenance ensures all components work together efficiently to transfer heat away from critical engine parts. Here's why cooling system care matters:

• Prevents catastrophic engine failure from overheating
• Maintains optimal engine operating temperatures
• Protects against corrosion inside the engine
• Extends the life of expensive engine components
• Improves fuel efficiency and performance
• Reduces the risk of roadside breakdowns

Regular cooling system service protects your investment and keeps you safely on the road. Our technicians handle a wide range of problems and stand behind every repair.
