We will not go into the details of the basic units and units of the car. Let's follow the path of least resistance. In a modern car for cooling, lubrication, and operating controls, brakes and other purposes use plenty of fluids. In the specific application can handle only an experienced mechanic, and we ordinary motorists – "kettles" in it. It suffices to basics.
The main thing that all the fluids differ in color, texture and flavor. The main thing in our business to know what color or that liquid, which its properties, viscosity, fluidity, and how it smells. If you find a car with your favorite spot, the first thing to note – size (the amount of leakage). Worry is if the spot size of nickels coins and more. Smaller spot size, unless it's certainly not fluid from the brake system greatly affect the performance of your car can not.
They rather a signal that in the near future to diagnose, stop by the station, but now you can just be a little more closely and monitor fluid levels under the hood of most frequent leakage of fluid. You found the leak. Right not to worry. The most common spot for any car – a spot of water. We all know what the dew. Here in your car and water condensation. Usually formed by water (condensate) flows to the right of center or left center of the vehicle. This is perfectly normal and you are seeing this, you know the reasons, can now breathe easy, there is no reason to worry. Motor oil stain. Color from light to dark brown, black. Engine oil viscous substance, "fat" with a stable smell of rubber. If you find a spot to check the oil level in the engine of your car. This is easily done, the main know where the probe. If you do not know, refer to the user section and look at checking the engine oil. If the oil level is low then top up as soon as possible. Remember, never topped up oil above the level of "swing" on the dipstick. Spot the coolant (antifreeze, antifreeze). The coolant is usually watery and slimy to the touch. By color: light green, yellow, pink, blue or even purple. Spot usually appears in front of the engine or in the radiator. After the engine cools down (not before!), Check the fluid level in the radiator and the coolant expansion tank. If the level is below the minimum refill. In the absence of fluid for topping up, you can use distilled water. Attention! Do not top up with tap water, it contains minerals that can corrode the cooling system.
