Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.Keep all parts free from contaminants. Contaminants may cause rapid wear and shorten component life.Plug or cap all open ports and tube assemblies.

Typical example
Turbo removed for clarity.
If necessary, position the dipstick tube assembly (39) away from exhaust manifold (38) in order to create sufficient clearance to allow removal.
Loosen bolts (37) in reverse numerical order. Refer to Illustration 6. Note: Loosening the bolts in reverse numerical order will help prevent distortion of the exhaust manifold.
