INSPECTION AFTER INSTALLATION
-
Before starting the engine, check oil/fluid levels including engine coolant and engine oil. If the levels are lower than required quantity, fill to the
specified level.
-
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide may generate a pounding noise during and
just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.
-
Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oil/fluids including engine oil and engine coolant.
-
Bleed air from passages in lines and hoses, such as in cooling system.
-
After cooling down the engine, again check oil/fluid levels including engine oil and engine coolant. Refill to specified level if necessary.
