Description

PERKINS INDUSTRIAL ENGINES:
• Perkins 1104D-E44T/1104D-E44TA/1106D-E66TA 1104/1106 Diesel (2004-present)


IMPORTANT:
185°F thermostat for Perkins 1104D/1106D engines (Cat C4.4/C6.6 equivalent). Cross-reference: Perkins 4133L066 = Cat 367-1817. The #1 ordering mistake: confusing 4133L066 with 4133L067 — both are 185°F but have different flow characteristics. Check your Perkins engine build list for the correct part number.
Cat engines under 210hp are Perkins-built. This thermostat fits Cat backhoes, excavators, and skid steers with 1104/1106 engines regardless of whether you search by Cat or Perkins part numbers.
Failure symptoms: engine running cold, slow warmup, or overheating under load if stuck closed. Always replace the gasket when replacing the thermostat.
⚠️ Confirm 4133L066 vs 4133L067 on your Perkins engine build list.
