BMW Coolant Systems Services that We Offer

As your one-stop-shop in Merrimack, we perform all types of coolant systems repair and maintenance services. From inspection to parts replacement, we’ve got you covered.

Here are some of the most popular cooling system services availed by our customers in Merrimack, NH:

Diagnostic inspection of cooling systems

We use the latest computer-aided tools and scanners to pinpoint the anomaly with your coolant systems. While most other shops can provide just a general description, we can determine the problem’s exact location and recommend the necessary repairs.

In numerous cases, cooling problems result in engine issues. These may trigger your check engine light and other dashboard error indicators. We are fully equipped with the best diagnostic equipment and tools required for the job.

Repairing coolant leaks

We provide comprehensive and accurate repairs to all kinds of coolant leaks. Whether your car’s radiator is leaking or its hoses are giving way, we can pinpoint the problem and fix it with a short turnaround. We also provide services for engine overheating problems caused by leaking fluids.

If you notice white smoke coming from the exhaust, the coolant may be leaking from a hose and getting burned. We can quickly find the worn hose and install a high-quality replacement.

Flushing the entire system via pressure testing

This is another of our specialties. We can flush your car’s entire cooling system by applying pressurized fluids and cleaning it thoroughly. This method removes rust, scale, and other impurities that may cause leaks or affect the efficiency of your BMW’s cooling systems over time.

Replacing worn water pumps

Your BMW’s water pump is a critical component in its cooling system. The purpose of the water pump is to circulate coolant through the engine and out of the radiator. A worn pump can lead to a lot more critical problems with your car, such as malfunctioning thermostats and warped cylinder heads.

Replacing the water pump on time will keep all these problems at bay. You can avoid costly repairs, downtime, and unexpected breakdowns in the future.

Cleaning corrosion from radiator fins, tubes, etc.

Over time, your BMW’s cooling system can accumulate a lot of rust and corrosion that can clog water passages and reduce their efficiency. We will use specialized tools and cleaning fluids to remove all rust and corrosion from your car’s cooling system. This service ensures better heat exchange in the radiator, leading to better fuel economy and engine performance.
