Cooling System Repair Services Austin, TX


Cooling System Repair!!!

Maintaining your automobile’s cooling system will prevent expensive repairs caused by overheating. Our staff of ASE certified technicians understand Cooling System Repair and know how to make sure your vehicle is in good working order.

 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 water mixture 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 Happy Hybrid Auto, 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 coolant, if you feel unsure about them bring your car to our service and repair center located in Austin, TX—we’re always happy to help!

Hybrid and Electric Vehicles have different cooling requirements, and often have multiple cooling systems. They all need periodic service. 

 

Radiator

Engines generate an enormous amount of heat and must be cooled continuously to function properly. The vehicle’s cooling system controls engine heat by circulating a liquid coolant throughout the engine. The coolant will become hot and will have to cool off. When this occurs, the coolant flows through the radiator, which is located at the front of the vehicle near the grill. In the radiator, airflow cools the fluid. Once cooled, the fluid is re-circulated throughout the engine. Without the radiator, the coolant would not transfer the heat to the air and would eventually cause the engine to overheat. Overtime, leaks can form in different components of the cooling system. At the first sign of a leak it’s important to have them fixed to prevent expensive damage to the engine. Happy Hybrid Auto prides itself on providing the Austin, TX area with superior service at the best possible price. If you’re experiencing any issues with your radiator, come by Happy Hybrid Auto, our expert ASE certified technicians are happy to help!

Thermostat

The cooling system’s thermostat is a valve that measures and regulates the temperature of coolant. The purpose of coolant is too cool off the engine as it burns fuel. It does this by circulating through the engine, absorbing heat, and carrying it to the radiator. Once in the radiator, the coolant is cooled by the air stream from the vehicle’s grill and then re-circulated through the engine. The thermostat’s job is to determine when the coolant has absorbed enough heat from the engine and can flow into the radiator. If it’s not hot enough, the thermostat will seal the top radiator hose, forcing the coolant to circulate throughout the engine. If the thermostat is stuck open, the engine will run cooler than it should and use more fuel. Conversely, a thermostat that is stuck closed will cause the engine to overheat and could cause serious damage to the engine. Symptoms of a bad thermostat include a knocking sound when accelerating, low temperature gauge readings, overheating, decrease in fuel economy, and a malfunctioning heater. If you experience any of these issues, bring your car in a soon as possible. Happy Hybrid Auto’s service and repair center is located in Austin, TX. We provide service to vehicles from the surrounding cities and neghborhoods of Round Rock, Cedar Park, Kyle, Buda, Granite Shoals, Lakeway, Pflugervile, and Westlake.

Water Pump

The water pump circulates the coolant mixture around the engine, through the heater core to provide cabin heating when needed, and through the radiator to cool the coolant. Typical water pump failures include leaking through the seals, or worn bearings. Water pumps can be belt driven, and a broken belt can cause your vehicle to overheat.

Hybrid Cooling Systems

Hybrid and Electric Vehicles typically use water pumps driven by an electric motor, as the pump must operate without the engine running. Many Hybrid vehicles will have multiple cooling systems, one for the ICE, Internal Combistion Engine, and one for the electrical components and electric traction motor.

Coolant

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 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 Happy Hybrid Auto, 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.
