Checking Tensioner Spring Tension
A belt tension gauge will not give an accurate measure of
the belt tension when automatic spring tensioner is used.
Measure tensioner spring tension using a torque wrench
and procedure outlined below:
1. Release tension on belt using a long-handled 1/2 inch
drive tool in tensioner arm. Remove belt from pulleys.
2. Release tension on tensioner arm and remove drive
tool.
3. Put a mark (A) on swing arm of tensioner as shown.
4. Measure 21 mm (0.83 in.) from mark (A) and put a
mark (B) on tensioner mounting base.

Checking Cooling System
CAUTION: Explosive release of fluids from
pressurized cooling system can cause
serious burns.
Shut off engine. Only remove filler cap when
cool enough to touch with bare hands. Slowly
loosen cap to first stop to relieve pressure
before removing completely.
IMPORTANT: Air must be expelled from cooling
system when system is refilled. Loosen
temperature sending unit fitting at rear of
cylinder head or plug in thermostat housing
to allow air to escape when filling system.
Retighten fitting or plug when all the air has
been expelled. Cooling system must be free
of air by time engine coolant temperature
reaches 80 °C (176 °F) or damage to EGR
cooler (if equipped) may result.

High Pressure Fluids
1. Check entire cooling system for leaks. Tighten all
clamps securely.
2. Thoroughly inspect all cooling system hoses for hard,
flimsy, or cracked conditions. Replace hoses if any of
the above conditions are found.
