Our Repair and Maintenance Services Include:

Belts
The fan belt, also referred to as a drive belt, connects your vehicle's engine to its front-mounted accessories. This belt is responsible for rotating the water pump and engine fan, ensuring a cool engine environment. Unfortunately, over time, your vehicle's fan belts can dry out and develop cracks, requiring a replacement.

It's important to entrust this kind of task to seasoned professionals. Our mechanics can conduct a thorough inspection of your car's belts, replace any worn ones, and ensure the installed belts are properly adjusted for optimum performance.

Coolant System Flush
A car's coolant system transfers excess heat from one part of the engine and dissipates it through the radiator fins. As time goes on, the coolant can become old and contaminated, negatively impacting the system's performance. To maintain optimal system function, consider regular coolant system flushes as part of your vehicle's cooling system maintenance.

Hoses
Hoses have the crucial role of transferring coolant and antifreeze throughout the engine's cooling system, including the radiator. With time, these hoses can dry out and develop cracks, leading to leaks. When it's time for replacement, you can rely on our team of experts for your vehicle repair needs.

Radiator Flush
Your vehicle's radiator is responsible for keeping the engine cool and safeguarding it from excessive heat. To maintain its effectiveness, the radiator must remain clean at all times. Sludge, rust, and other solid deposits can accumulate inside the radiator, leading to clogs and reduced system efficiency. This, in turn, can negatively affect your vehicle's performance. Incorporating regular radiator flushes into your routine car maintenance schedule is essential.

Radiators
Radiators serve as heat exchangers, cooling your car's internal combustion engine. They accomplish this by circulating engine coolant through the engine block and then releasing the heat into the atmosphere through radiation.

Radiators consist of a set of tubes through which engine coolant flows, surrounded by fins. When a radiator fails, the excess heat produced by the engine could potentially damage vital engine components. To prevent such issues, it's crucial to have your radiator regularly serviced.

Coolant FAQs

What is causing my coolant light to come on?

If the dashboard light is red, indicating your car is overheating then you should pull over as soon as it is safe to do so and switch off the engine. If the coolant level is low or there is another problem with your cooling system, you could cause serious damage by continuing to drive.

When should I do a coolant flush?

Your vehicle's owner's manual will recommend getting the coolant flushed about every 30,000 miles or three to five years, whichever comes first. Make sure to consult your owner's manual as some outline a more specific interval depending on the vehicle's make and model and your driving habits.

Why is my coolant leaking?

Corrosion within the radiator is the leading cause of a coolant leak. As the radiator tubes get older and weaker, sediment or debris collects inside and causes a leak. The sealing gasket between the tank and the radiator can also wear out, and lead to a leak.

How do I know what coolant I should use?

Your car's owner's manual provides a wealth of information. Follow the recommendations in your car's owner's manual to the letter unless otherwise recommended by the manufacturer or auto repair professionals. It will tell you what type of coolant is best to use in your vehicle. If you don't have a copy of your owner's manual, you can most likely find the information you need on the manufacturer's website.

Radiator FAQs

When should the radiator in my car be replaced?

Often, radiators will last for the entire life of a car. On average a radiator lasts 8 to 10 years. However, there are a few factors that can reduce a radiator's working life such as improper maintenance, driving habits and environmental conditions.

What does radiator service include?

Radiator service starts with draining the system. Then we flush the radiator and engine block, inspecting all hoses to make sure they're not cracked. Next we refill the radiator with fresh coolant and finish by pressure testing the radiator cap and cooling system.

What is causing my engine to overheat?

The most common reason a car overheats is a lack of coolant or a coolant leak. However, if you have an older vehicle, it may also indicate that it is time to replace your radiator, thermostat, water pump or heater core. If it continues to be a problem that you can't fix, your best bet is to bring it to our shop in Herndon.

What is the average lifespan of a radiator?

While radiators usually last 8-10 years, some factors can shorten their lifespan. Watch for signs of deterioration to know when replacement is needed.
