Cooling fluid leaks can occur anywhere in the cooling system. In nine out of ten cases, the leakage of the cooling Jew is easy to find, because you can see where the liquid drips, seeps or flows out. Open the hood and inspect the engine and cooling system to detect signs of fluid leakage from the engine, radiator or hose. The color of the coolant can be green, orange or yellow, depending on the type of antifreeze. The most common places where the leak occurs:
Water pump – LOUK OF THE CARNE OF COURSE will allow the coolant to drip from the ventilation opening under the pulley of the water pump shaft. The leak may be from under the gasket between the body and the back cover. See if there are spots on the outside of the water pump or engine.
Radiators – leaks around the upper hose, from vibration, can form within the radiator. At the seams where the tanks are connected to the tubes, there is often a leak, especially on aluminum radiators with plastic tanks. On copper / brass radiators, leaks occur on the soldering of pipes as a result of internal corrosion caused by an old coolant, which has never been replaced, can also eat metal in the radiator, which will lead to a leak.
Most cooling systems are designed to work from 0. 6 to 1. 0 AT. If the radiator cannot maintain pressure, your engine can overheat and lose the coolant.
Check the hoses to cracks, cuts, soft spots, blisters.
Cracks, cuts or splitting in the hoses of a radiator or stove also cause coolant leaks. Corrosion at the joints of the hose or dangling or damaged clamps can also allow the coolant to flow.
The engine plugs are traffic jams from the engine block and / or cylinder block head. Corrosion from the inside can form in steel traffic jams, and can cause leaks that are difficult to see, due to the location of the exhaust manifold, engine support or other parts of the engine. On V6 and V8 engines, traffic jams are most easy to see from under the car.
Tel heating – the main heater is under the dashboard. It is out of sight to see the leak directly. But if the stove flows (or hose), the cooling liquid will seep out of the lower part and will drip to the floor inside the cabin. Look at the spots or wet spots at the bottom of the plastic ventilation and air conditioning case, or to the floor from the passenger side.
The gasket of the intake manifold can also cause coolant leakage into the crankcase or drip down.
