We conduct an extensive interview process to ensure our staff have the proper experience and skill to meet our standards of mechanic needs.

Oil and Oil Filter Service

Experts recommend changing the oil and oil filter in your vehicle every 6 months or 6,000 miles, whichever is first. It’s an essential way to maximize engine protection. Oil changes at 10,000 miles are usually too long an interval for most common driving conditions. Unless using proper Synthetic oil as mandated by the vehicle manufacturer like Mercedes Benz, BMW, Mini Cooper and many more makes use. Even then you should have the oil changed every 6,000 Miles considering our hot temperatures in Miami and our idle time in traffic which does not reflect on your mile count.

Cooling System Service

Flush cooling system, pressure test, coolant hose leak, radiator, cooling pipes, coolant reservoir, thermostat assembly, water pump and connectors.

Air Conditioning Service and Repairs

One of our trained Air Conditioning specialists will inspect your car’s air conditioner, all AC lines, evaporator and compressor for leaks and wear. A/C not cooling we can help.

Using specialized equipment our technicians will quickly and effectively clean the intake manifold, ports, intake valves, and combustion chamber. Install injector cleaning additives in the tank. This service will restore lost power and performance and will reduce harmful exhaust emissions.

Power Steering Flush

Our technicians use a powerful cleaner to dissolve gum and varnish in your car’s power steering unit. Next, we will flush old, worn-out contaminated fluid and install fresh new fluid fortified with a special antioxidant and anti-wear ingredients to prevent expensive mechanical failure.

Car Fluids and What to Know

By keeping your car fluids at their proper levels, a vehicle is kept in good working order. Fluids are essential to the smooth operation of many of a car’s systems including the engine, brake system and transmission. Letting them drop below the fill line or, worse yet, dry out can be a recipe for disaster. While many car repairs require a skilled professional, maintaining the levels of essential car fluids is vital such as motor oil, brake fluid, automatic transmission fluid, power steering fluid and coolant. Have them  checked or replaced at ADVANCED AUTO DIAGNOSTICS. Consider the following seven car fluids and their importance to a car.

7 Essential Car Fluids and What to Know about Each in your vehicle:

Motor Oil

Motor oil is the most important fluid in every car with an internal combustion engine. Oil lubricates the moving parts in a car engine’s crankcase, preventing the high heat and friction that results during engine operation from destroying the pistons, valves and other components. Without oil, a running engine will seize up in a short time, making the engine virtually unusable.

Brake Fluid

Brake fluid is by far the most important car fluid in terms of passenger safety. A car’s brake line system is a fully-sealed network that uses hydraulic pressure to control the car’s ability to stop. When a driver presses down on the brake pedal, the brake fluid compresses, transferring the hydraulic force to the pads and shoes that cause the friction necessary to stop the vehicle. If brake fluid leaks or if too much air gets into the brake line, a car’s ability to stop will be compromised.


Coolant is most commonly a 50/50 combination of water and specialized radiator coolant. In colder climates this ratio will lean more heavily towards coolant. Coolant is a heat transfer fluid. It cycles around a running engine, collecting heat as it does and returns it to the radiator. From there, it is transferred to the air. Without proper coolant levels, a car will quickly overheat and be inoperable.

Transmission Fluid

Transmission fluid is reddish in hue and usually does not have to be checked by a car owner. Similar to motor oil, transmission fluid cools and lubricates the inner parts of the transmission, ensuring that the engagement of the car’s system of gears works without a hitch.

Power Steering Fluid

This fluid, pressurized by a small hydraulic pump powered by the engine, helps to make turning a car easier. When working at proper levels, power steering fluid increases the ability of the steering mechanism to direct the tires.

Battery Fluid

Cars with maintenance-free batteries don’t require checking the battery fluid. Other car batteries, however, must have their individual cells refilled from time to time. Fill up each cell to the bottom of the fill line with distilled water.

Windshield Wiper Fluid

While this is a non-essential fluid in terms of a car’s ability to operate and stop, windshield wiper fluid provides a fast means of clearing the windshield of dust, bug residue and other particles while driving. The fluid is basically liquid soap and is very easy to maintain. 

Simply by taking the time to bring your vehicle into ADVANCED AUTO DIAGNOSTICS periodically we will check these fluids, to ensure your car enjoys a healthy, safe level of operation. While some are more important than others, they all contribute to a sound automobile.

I am 55 years old and not a fan of the “online” world but I felt compelled to put a review for these guys. I must thank David and the staff behind him for their honesty and integrity. They saved me around $3,000 in unnecessary repairs that were suggested by my dealer!!! I ran these guys through 2 honesty tests and they passed with flying colors. Good people still exist !!!!
