Leaks in the cooling system usually leave a trail of white or rusty deposits
2. Check up a condition and reliability of fastening of all tubes and hoses concerning the engine. Make sure all clamps are in place and securely tightened. Broken or lost clamps can cause very serious consequences in the future.
3. Carefully check the entire length of the radiator and heater hoses. If signs of cracking, rubber degradation or fraying are noticed, replace the hose. Cracks become more visible as the hose is compressed. Pay attention to the hose clamps to the radiator and to the engine. A clamp that is too tight can cut through the hose and cause a leak.
4. Inspect all elements and connections of the cooling system for leaks. If a leak is found, replace the gasket or seal (see chapter 3).
5. If the car is equipped with an automatic transmission, check the hoses of the transmission cooling system in the same way.
6. Raise the vehicle and inspect the fuel tank and filler neck for cracks, holes, or other damage. Pay special attention to the connection of the filler neck with the tank. Sometimes leaks occur due to cracks in the connecting hose or a poorly tightened clamp.
7. Inspect all rubber hoses and metal tubes coming from the tank. Check if the connections are securely tightened, if there are any creases on the tubes, if the hoses are in good condition. Pay attention to the vent hoses, which tend to wrap around the filler neck and can therefore become kinked or kinked. Trace the hoses all the way to the front of the vehicle. Replace defective sections.
8. Carefully inspect the metal tubes of the brake system, passing under the bottom of the car. If the tubes are damaged or rusty, replace them.
9. In the engine compartment, check the reliability of the connection of all fuel lines. Inspect the vacuum hoses for kinks, fraying, or signs of decay.
10. Check up a condition of hoses and tubes of a hydrosystem of a steering.
