• Aftermarket coolant temperature sender (OE 130-8299) for Caterpillar G3408C and G3516B industrial engines — accurately monitors engine jacket water temperature in wheel loaders, stationary generator sets, and large-scale power equipment for reliable gauge display.
• This is a passive NTC thermistor sender (not a switch or digital sensor), providing a resistance-based signal that precisely matches the OEM calibration curve. It enables accurate analog temperature readings but does not control cooling fans, trigger alarms, or interact with emission systems.
• Sealed brass body with 1/8" NPT thread and corrosion-resistant terminal withstands high heat, vibration, and coolant exposure in demanding mining, power generation, and material handling applications across North America.
• Direct OEM-fit replacement with identical electrical characteristics and mounting profile. Install in minutes with standard tools — no wiring changes or recalibration needed.
• ⚠️ For off-road industrial and power generation equipment only. Not approved for on-highway vehicles, agricultural tractors, marine propulsion systems, irrigation pumps, pesticide sprayers, or refrigeration units.
