a. Insert Tool (A) between the lower oil pan and the upper oil pan.
CAUTION:
• Be careful not to damage the mating surface.
• Do not insert a screwdriver or similar tool, this will dam-
age the mating surfaces.

• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner dr ops 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 leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
