Description

CATERPILLAR EXCAVATORS:
• Caterpillar 311D LRR/312D/312D L/313D/314D CR/314D LCR C4.2 4.2L Diesel (2007-2014)
• Caterpillar 319D L/320D/320D FM/320D GC/320D L/320D RR C6.4 6.4L Diesel (2006-2014)


IMPORTANT:
160°F thermostat element for Cat C4.2 engines. Fits Cat 311D/312D/313D excavators (2007-2014).
The #1 ordering mistake: this thermostat opens at 160°F — NOT the more common 180°F. The C4.2 engine is spec'd for a lower operating temperature than the C4.4 or C6.6 families. Do NOT substitute a 180°F stat — it will cause the engine to run hotter than designed.
Note: the C4.2 is a Cat-exclusive engine, not a Perkins or Mitsubishi rebrand. It has no direct Perkins cross-reference.
Failure symptoms: overcooling (stuck open), overheating (stuck closed), temperature gauge reading erratically, or engine derate from high coolant temp code.
⚠️ Confirm 160°F rating — do NOT substitute 180°F.
