Perform the procedure to check for leaks of lubricants, fluids or exhaust gases:
Before starting the engine, check the levels of all operating fluids (engine oil, coolant, etc.). If necessary, bring fluid levels to normal.
Move the ignition switch to position «ON» (without starting the engine). The fuel lines will begin to build up pressure, check for fuel leaks at the connections.
Start the engine. While increasing the engine speed, check again for fuel leaks at the connections.
With the engine running, check for abnormal noises and vibrations.
Warm up the engine thoroughly and check for fuel, engine oil or other fluid leaks.
Remove air from hydraulic systems.
After the engine has cooled down, check the fluid levels again. If necessary, add fluid to the required level.
