Your coolant system is what keeps your car engine from overheating in the summer and from freezing in the winter. It works by coolant being pumped by the water pump through the engine into the radiator. The coolant takes heat away from the engine and dispels it through the radiator by airflow that comes through the grill of the car. If this system breaks down or isn’t maintained it can cause damage to your water pump. This damage over time will affect not only the coolant system but also your engine and engine’s performance as well.

Getting a coolant flush is absolutely necessary for a car’s regular maintenance. Getting one every couple of years helps clear away the gunk and sediment that has been building up in your car’s coolant system. You can see in the photo that this buildup of rust and other gunk will make your car’s co0ling system fail. So getting a coolant system flush will improve the efficiency of your car. In the process, it will also replace old coolant with new better performing coolant.


Engine oil leaks are the most common of all automotive fluid leaks With the number of seals and gaskets located around the engine bay, oil can leak from almost anywhere. If the leak occurred some time before you notice it, the oil may have spread far from the real source. Air moving through the engine by driving or being pushed through the cooling fan can cause the leaking oil to cover areas far and wide.

Also, if it isn’t a large and/or obvious leak, it will take some investigating to locate the source as it may also be caked with dirt and debris. The fastest way to spot a leak is to use a leak detector kit.

These kits come with fluorescent dyes that are formulated for specific engine fluids and a UV light. When the oil starts coming out of the source of the leak, the fluorescent dye will leak out with it. Shining the UV light around the engine bay will make the dye glow, usually a fluorescent green that is easy to spot.


What are the components of a brake system in a car?

The pads are attached to a brake caliper assembly that frames the rotor. Located on the rear of the vehicle, drum brakes feature wheel cylinders, brake shoes and a brake drum.

When the brake pedal is pressed, the brake shoes are forced into the brake drum by the wheel cylinders, bringing the vehicle to a stop. Braking systems in passenger vehicles use two primary types of brakes: disc brakes and drum brakes.

While they both bring a vehicle to a stop, they differ in design and operation. Disc brakes are the only type used in the front of vehicles but may be found at all four wheels.


What is suspension system in automotive?

In a nutshell, your car's suspension system is a protective lattice of shock-absorbing components such as springs and dampers. Your car's suspension helps ensure that your drive is safe and smooth by absorbing the energy from various road bumps and other kinetic impacts.

Like we mentioned above, most experts recommend replacing suspension parts after 50,000 to 100,000 miles. However, this is simply a recommendation that is based on general conditions. Every driver has something unique about their car, driving style, and even the roads they drive on often. What happens if you don't replace suspension?

Over time, shocks and struts can lose their ability to control weight transfer; this is what causes you to feel like you're not in control of your vehicle. This can be dangerous, especially if your tires lose contact with the pavement, making it difficult to control your vehicle in an emergency situation.


What does the cabin air filter do in a car?

The cabin air filter in your vehicle helps to ensure that there is a proper ventilation system for the health and safety of all passengers. Without a working cabin air filter, the air inside of a vehicle's cabin is prone to having higher levels of harmful and odorous exhaust gases than the air outside of the cabin.

What happens if you don't change your cabin air filter?

If you don't change your cabin air filter, the filter will become more clogged with dirt and debris and the efficiency of the filter and your car's HVAC system will be compromised. The air volume into your passenger compartment will be continually reduced which will lead to the issue of foul odors inside your car.


A fluid exchange is the process of removing old, dirty fluids from your car and replacing them with fresh, new fluids. Fluids are essential for keeping your car running smoothly and preventing expensive repairs. Over time, fluids break down and become contaminated with dirt, debris, and other harmful particles.

How often should I exchange my fluids?

The frequency of your fluid exchanges will depend on the type of fluid and the manufacturer’s recommendations. In general, though, most fluids should be exchanged every 30,000 miles or so. If you drive in stop-and-go traffic or in extreme conditions like very hot or cold weather, engine oil may need to be exchanged more.

A fluid exchange is an important part of car maintenance. By exchanging your fluids regularly, you can prevent expensive repairs and keep your car running like new. So don’t wait – if it’s been a while since your last fluid exchange, schedule one today!
