Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
^
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level.
^
Use procedure below to check for fuel leakage.
^
Turn ignition switch "ON" (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
^
Start engine. With engine speed increased, check again for fuel leakage at connection points.
^
Run engine to check for unusual noise and vibration.
NOTE: If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack 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 gases, or any oil/fluids including engine oil and engine coolant.
^
