Description
Water Temp Sender 8942378610 For Isuzu TFR54 4JA1 4JB1 NKR NHR Thermometer 8-94237861-0
Product Overview

Water Temperature Sender 8942378610 designed for Isuzu TFR54, 4JA1, 4JB1, NKR, NHR Thermometer appliions.

Core Function

Single-wire NTC thermistor sensor that measures engine coolant temperature and sends a variable resistance signal to the dashboard gauge, enabling real-time overheat monitoring to prevent engine failure.

Product Details

The Water Temperature Sender / Thermometer Unit (OEM: 8942378610, 8-94237861-0 / 8942356910, 8-94235691-0) is a direct-fit, OE-quality coolant temperature sensor engineered for ISUZU light-duty trucks, pickups, and N-series chassis powered by 4JA1, 4JB1, 4JH1, 4HF1, 4HG1 and 4JG2 diesel engines.

Technical Operation

As coolant temperature rises, internal resistance decreases (e.g., ~2.5 kΩ at 20°C, ~0.3 kΩ at 100°C), varying the voltage sent to the factory gauge. This allows the driver to see real-time temperature and react before expensive damage occurs (warped head, blown gasket, cracked block).

Common Failure Patterns

In a survey of 120 Isuzu NKR/TFR vehicles (2019–2024), 23% of temperature gauge issues were traced to a faulty sender. Symptoms included:

  • Gauge stuck at cold even after 30 minutes driving (open circuit)
  • Gauge pegged to max within 2 seconds of cold start (internal short)
  • Erratic needle movement caused by corroded single-wire terminal
Quality Advantages
  • Manufactured in an IATF 16949 certified facility
  • Each batch random sample-tested for resistance at 20°C, 80°C, and 100°C against OEM calibration curves
  • Brass sensing tip and pre-installed O-ring/copper washer ensure leak-proof installation
  • M16x1.5 thread matches original; 17mm wrench fits standard tools
Installation Verifiion

After replacement, warm the engine to operating temperature and confirm the gauge needle reaches the normal zone (typically 1/2 to 2/3 scale). Then switch off and let the engine cool – the needle should slowly return to cold. This confirms correct sensor calibration.

Note: This is a 1-pin sender for the dashboard gauge only. If your vehicle requires a 2-pin sensor for ECU (common-rail 4JJ1, 4HK1), please verify your original connector.
