PERFORMANCE ORDER
1. Visually examine the adjoining surfaces of the engine, laying and epiploons on existence of traces of leak of cooling liquid or oil. Pay special attention to areas around connections of a cover of a head of the block of cylinders, heads of the block of cylinders, an oil filter and an oil case. Do not forget that through certain time through connections a small amount of oil can begin to filter. It is normal. If you find serious leak, replace the passing laying or an epiploon (see subsection 9.1.5 and subsection 9.2.5).
2. Also check reliability and a condition of all tubes and hoses of the engine, and also tubes and hoses of the brake system and tubes of a power supply system. Check that all clips and arms were on the place and were in good shape. If clips are broken or are absent, then hoses, tubes or wires will dangle and be used up about surrounding elements that can lead to more serious problems in the future.
3. Carefully check hoses of a radiator and hoses of an oven on all their length. Replace hoses which burst, were inflated or wore out. Cracks are better visible if to squeeze a hose. Draw close attention to hose collars which fix hoses to cooling system elements. Hose collars can jam or puncture hoses that will lead to leak of cooling liquid. If the twisting collars were used, it is recommended to replace them with standard coupling collars.
Prevention

Most quicker thickness of brake slips can be measured through an opening on a support of a forward brake


4. Check all elements of the cooling system (hoses, connections, etc.) for existence of leaks.
5. If cooling system, any of elements, it is faulty, replace it or laying, being guided by the instructions provided in subsection 4.12.
6. Having lifted the car, examine the fuel tank and a jellied mouth of the fuel tank on existence of punctures, cracks or other damages. It is necessary to pay special attention to connection between a jellied mouth and the fuel tank. Sometimes the rubber tube of a jellied mouth or a connecting hose can proceed because of the weakened fixing collars or wear of rubber.
7. Carefully examine all rubber hoses and metal tubes going from the fuel tank. Check reliability of connections and check that there were no worn-out hoses, the broken tubes or other damages. Pay special attention to ventilating tubes and hoses which often are wrapped around a jellied mouth and can be pressed or broken. Check a condition of tubes on all length to a forward part of the car. Replace the damaged sections if it is necessary. Until the car is lifted, take an opportunity to check also the tubes and hoses of the brake system located under the body bottom.
8. In a motive compartment check reliability of fastenings of all fuel, vacuum and brake hoses and connection of tubes, and also check that hoses were not pressed, used up or damaged.
