1. Visually inspect the engine joints, gaskets and seals for signs of leaks. Pay particular attention to the areas around the camshaft cover, cylinder head, oil filter and oil pan. Over time, minor leaks are bound to occur in these areas, and this is completely acceptable - pay attention only to major leaks. If such a leak is found, replace the appropriate gasket or seal, following the appropriate Section of this manual.
2. Also check the reliability and condition of the connections of all tubes and hoses to the engine. Make sure that all clamps and fasteners are in good condition. Faulty clamps can lead to chafing of hoses, pipes or wiring, which can cause more serious problems.
3. Carefully inspect the radiator and heater hoses. Replace any hoses that are cracked, swollen, or worn. Pay special attention to the clamps that secure the hoses to the cooling system components. The clamps can pinch or puncture the hoses, causing leaks in the cooling system.
4. Inspect all components of the cooling system (hoses, joint surfaces, etc.) for signs of leaks and replace the required component or gasket, following Section 3.
5. Where applicable, inspect transmission fluid cooler hoses for signs of leaks or wear.
