Cooling System Repair
On average, a four-cylinder vehicle travelling at a speed of 50 mph will produce 4,000 explosions per minute in its engine. These explosions create a massive amount of heat that could destroy the engine if not controlled properly–that’s where the cooling system comes in. A vehicle’s cooling system circulates a liquid coolant through the engine and then out to the radiator where it is cooled by air coming through the front grill. The main components of a cooling system include passages within the engine block and heads, a water pump to circulate coolant, a thermostat to monitor coolant temperature, and a radiator to cool the liquid after it has travelled through the engine. As the anti-freeze travels through these passages, it picks up heat from the engine and carries it away to the radiator where it is cooled. Once cooled, the liquid is sent back through the engine. It’s important to maintain coolant levels to prevent engine overheating and potential damage. At Lake Norman Tire & Auto Center, we recommend that coolant be changed every 24,000 miles and that any cracked, leaking, or brittle hoses be replaced at the same time. There are specific requirements for mixing coolant, if you feel unsure about them bring your car to our service and repair center located in Mooresville, NC—we’re always happy to help!
As the engine burns fuel to generate mechanical force it creates an enormous amount of heat. If not dealt with, this heat would destroy the engine within a matter of minutes. To solve this problem, a liquid is used that can withstand temperatures above 250 degrees without boiling and temperatures below zero without freezing. The liquid is generally a mixture of antifreeze and water that also contains additives to prevent rust and corrosion. This coolant is circulated through the engine where it picks up heat and carries it to the radiator. Once in the radiator, air coming in from the grill cools the liquid and it is re-circulated. Overtime, the coolant can become corrosive and, if not flushed, can cause problems in the cooling system. Corrosive coolant will eventually lead to overheating and coolant leaks. At Lake Norman Tire & Auto Center, we recommend that your vehicle’s coolant be flushed on a regular basis to prevent unnecessary damage to the cooling system. Any leaking, brittle, spongy, or cracked hoses should be replaced before the antifreeze is replaced.
