CAT 288-8390 Temperature Sensor is identified by Caterpillar part number 288-8390. This component is used to sense low-temperature conditions for Caterpillar engine and machine monitoring/control systems. The page below combines official CAT product identification, public technical specifications and major compatible models with practical ordering checks for B2B buyers. Final compatibility should always be confirmed by machine or engine serial number before shipment.

What This Part Does

An incorrect temperature signal can affect monitoring, diagnostics and system control depending on the sensor location.

Key Features

• CAT low-temperature sensing component
• 4-pin Ampseal electrical connection
• Used in air, fuel, engine-oil, cooling and hydraulic systems depending on arrangement

Technical Specifications

Major Compatible CAT Models

• Wheel Loaders: 988, 988H, 988K, 990, 990K, 992K, 993K, 994H

These are major applications from Caterpillar public parts information, not a complete serial-number fitment list. Additional CAT arrangements may use the same part number.

Before Ordering

• Confirm the sensor location and monitored system: air, fuel, engine oil, coolant or hydraulics.
• Verify the 4-pin Ampseal connector.
• Check the #6 (9/16-18-2A) thread specification.
• Provide machine model and serial number because the same machine can use multiple temperature sensors.
