• Lube oil filter gasket with engine oil.
• Install oil filter as per filter manufacturers
instructions. DO NOT OVER TIGHTEN
• Fill crankcase with engine oil.
• Start engine & run approximately 60 seconds.
• Shut down engine, wait approximately 2 - 5 minutes
and then check oil level.
• When oil level is satisfactory start engine and check
for any possible leaks.
• Repair any/all leaks before returning unit to service.
Engine Oil Specification : See, Lubrication System
section

Inspect Accessory Drive Belts

See, "Testing & Adjusting" of Cooling System Section.

Inspect electrical system

• Clean battery outer surfaces with a mixture of baking
soda and water.
• Inspect battery outer surfaces for damage. Replace
as required.
• Remove battery cables and clean.
• Inspect battery cables for worn or missing insulation,
frayed wire and/or corrosion. Replace as required.
Inspect Vacuum Lines and Fittings
• Visually inspect vacuum lines and fittings for physical
damage such as brittleness, cracks, kinks and
misrouting. Repair/replace as required.
• Solvent damage may cause vacuum lines to become
soft. Vacuum lines damaged by oil and/or other
solvents may collapse when the engine is running
effectively closing the passage inside the line.

Check Coolant Level

• Engine must be off and cold.
• NEVER REMOVE THE PRESSURE CAP ON A HOT
ENGINE.
• The coolant level should be equal to the "COLD"
mark on the coolant recovery tank. Periodically
remove the cooling system pressure cap and check
coolant level inside system. The coolant level should
be equal to the sealing surface of the pressure cap.
If level is low replace pressure cap and repair any/all
other leaks.
• On closed systems visually inspect the coolant
recovery tank and hoses for physical damage
G424 Service Manual
NOTE
• On open systems carefully remove cooling system
pressure cap. Coolant level will be approximately 30-
40 mm below pressure cap sealing surface. If level is
low replace pressure cap and repair any/all other
leaks.

Inspect Coolant Hoses

• Visually inspect coolant hoses and clamps.
• Replace any hose that shows signs of swelling,
cracking, abrasion
damage/deterioration.
• Top-up cooling system with approved coolant.

Inspect Ignition System

• Remove and inspect spark plugs. Replace as
required.
• Test secondary wires with an Ohmmeter. Maximum
resistance repair replace as required.
• Remove distributor cap and perform visual inspection
of distributor cap and rotor. Replace cap & rotor if
corrosion is found on contacts.
• Inspect distributor breaker unit and housing for signs
of corrosion. Repair replace as required.
Replace Spark Plugs
• Utilizing a gentle twisting motion remove the
secondary high voltage leads from the spark plugs.
Replace any damaged leads.
• Remove the spark plugs.
• Gap new spark plugs to proper specs.
• Apply anti-seize compound to spark plug threads.
• Install spark plugs.
• Do not over tighten.
• Install secondary high voltage leads.
