INSPECTION AFTER INSTALLATION
The following are procedures for checking fluid leakage, lubricant leakage.
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If any are less than the required quantity, fill them to the specified level. Refer to Fluids and Lubricants.
Follow the procedure below to check for fuel leakage.
Turn ignition switch to the “ON” position (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
NOTE:If hydraulic pressure inside chain tensioner drops after removal/installation, slack in guide may generate a pounding noise during and just after the engine start. However, this does not indicate a malfunction. The noise will stop after hydraulic pressure rises.
Warm up engine thoroughly to check that there is no leakage of fuel, or any oil/fluids including engine oil and engine coolant.
Bleed air from lines and hoses of applicable lines, such as in cooling system.
