Inspection of the Cooling System
A coolant system properly maintained and protected with supplemental coolant
inhibitors can be operated up to the intervals listed in this manual using the
appropriate engine duty cycle, Refer to section "Preventive Maintenance Tables".
At these intervals the coolant must be drained and disposed of in an
environmentally responsible manner according to state and/or federal
recommendations. Authorized Detroit™ service outlets are properly equipped for
this type of service.
Inspect the cooling system as follows:
Checking for Coolant Leaks
Perform daily visual checks for cooling system leaks. Look for an accumulation of
coolant when the engine is running and when it is stopped. Check all cooling
system pipes and hoses for damage and leaks and ensure they are positioned to
avoid chafing, and are securely fastened. Coolant leaks may be more apparent on
an engine when it is cold. If coolant leaks exist, it may be necessary to take the
vehicle to an authorized Detroit™ service outlet.
Checking the Coolant Level
The coolant level should be inspected daily as part of the pre-start inspection, Refer
to section "Checking the Coolant Level (Cold Check)". If necessary, fill the cooling
system with approved coolant, Refer to section "How to Select Coolants".
Testing the Coolant
Refer to the Coolant Requirements For Engine Cooling Systems brochure (DDC-
SVC-BRO-0002) for the latest information on coolants and coolant testing.
Inspection of the Exhaust System
Inspection of the Exhaust System
Inspect the exhaust system as recommended in the maintenance tables using the
appropriate engine duty cycle, Refer to section "Preventive Maintenance Tables".
Inspect the exhaust system as follows:
1. Check the exhaust manifold and other connections for leaks tightness.
2. Inspect the exhaust pipes for damage or restrictions.
NOTE:
If any of the above conditions exist, it may be necessary to take the
vehicle to an authorized Detroit™ service outlet.
