• The cylinder or cylinders having poor combus-
tion can be identified by checking the tempera-
ture of the individual exhaust runners using a
non-contact thermometer.
• Look primarily for evenness of temperatures
between the exhaust runners.
• If a mis-firing cylinder is identified, contact the
partnering Caterpillar dealer.
6. If the cooling system pressurizes immediately on
start-up, the cooling system has been breached
by engine compression. This is typical of a head-
gasket, cylinder liner, or cylinder head failure.
Contact the partnering Caterpillar dealer.
