2. CAUTION: Explosive release of fluids from
pressurized cooling system can cause
serious burns.
Only remove filler cap when engine is cold
or when cool enough to touch with bare
hands. Slowly loosen cap to first stop to
relieve pressure before removing completely.
Remove radiator cap (E) and check coolant level
which should be at bottom of filler neck. Fill radiator
with proper coolant solution if level is low. (See
DIESEL ENGINE COOLANT). Check overall cooling
system for leaks.

3. If air filter has a dust unloading valve (C), squeeze
valve tip to release any trapped dirt particles.
4. Check air intake restriction indicator (D). When
indicator is red, air filter needs to be cleaned.
IMPORTANT: Maximum air intake restriction is
6.25 kPa (0.06 bar; 1.0 psi) (25 in. H
2
O).
A clogged air cleaner element will
cause excessive intake restriction and a
reduced air supply to the engine.
5. Make a thorough inspection of the engine
compartment.
NOTE: Wipe all fittings, caps and plugs before performing
any maintenance to reduce the chance of system
contamination.
