76℃ Thermostat for Caterpillar 3512 3516C 3516B 3512C 3512B C32 3508B 3508C

76℃ Thermostat for Caterpillar

This 76℃ thermostat for Caterpillar 3512, 3516C, 3516B, 3512C, 3512B, C32, 3508B, and 3508C engines regulates coolant flow to maintain optimal operating temperature. It is a direct replacement component designed to support consistent engine thermal management.

Overview

This 76℃ thermostat is a temperature-regulated valve that opens and closes to control engine coolant circulation, helping maintain stable operating temperatures under load. It is intended for use with Caterpillar heavy-duty industrial and marine diesel engines, including the 3512, 3516, and C32 series. The 76℃ opening temperature is selected for applications that require a lower coolant temperature setpoint.

Built For Performance

• 76℃ opening temperature matches specifications for low-temperature cooling circuits
• Precision-wax element responds to coolant temperature changes for consistent regulation
• Constructed with corrosion-resistant materials for extended service life
• Direct-fit design simplifies installation during routine cooling system maintenance
• Compatible with standard coolant flow rates of large displacement diesel engines
• Rigid frame construction prevents distortion under high pressure

Specs At A Glance

Good To Know

Q: How do I verify this thermostat fits my specific engine? A: Cross-reference your engine serial number prefix and cooling system part number with the machine's service manual, as minor design changes can occur across production years.

Q: What happens if the thermostat fails to open? A: A stuck-closed thermostat can cause overheating, so it is critical to replace the unit during any cooling system repair to avoid engine damage.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
