Post-installation checks
Checking for leaks
1. Before starting the engine, check the oil and engine fluid levels. If the level is below the required level, top up.
2. Use the following procedure to check for fuel leaks:
Turn the ignition switch to the "ON" position (but do not start the engine). After creating pressure in the fuel lines, check for leaks in the connections.
Start the engine. Increase the engine speed and check again for leaks in the connections.
3. Let the engine run to check for extraneous noise and vibration.
Note: If the hydraulic pressure inside the chain tensioner drops after removal/installation, the slack in the tensioner shoe may cause a rattling noise during and immediately after starting the engine. However, this does not indicate a malfunction. The noise will stop after the pressure is built up.
4. Warm up the engine thoroughly to ensure there are no fuel or engine fluid leaks (including engine oil and coolant).
5. Remove air by bleeding from the pipelines and hoses of the hydraulic systems that were disconnected (for example, engine cooling systems).
6. After the engine has cooled down, check the engine oil/fluid levels again. If necessary, top up to the required level.
