GM GENUINE PARTS Engine Cooling Temperature Sensor 15326386 – OE Fit, Reliable Coolant Temp Monitoring

The GM Genuine Parts 213-928 (15326386) Engine Cooling Temperature Sensor is an OEM-grade replacement that accurately monitors coolant temperature and relays readings to your vehicle’s control systems.

This multi-purpose temperature sensor from GM Genuine Parts is built to the original equipment specifications used by General Motors. It measures the temperature of engine coolant and other fluids to provide reliable input for radiator fans, temperature gauges, and warning indicators. As a factory-recommended replacement, it’s designed for proper fit, consistent performance, and long-term durability in compatible GM vehicles.

How does this sensor maintain proper engine temperature control?

The sensor detects changes in coolant temperature and transmits an electrical signal to the vehicle’s control module or gauge cluster. The control module uses that signal to activate or deactivate cooling fans, update dash readouts, or trigger alerts so the engine is regulated within its intended operating range.

• Direct temperature-to-voltage output for control-module response
• Works with radiator fan relays and gauge inputs
• Helps prevent overheating by signaling cooling systems promptly
• Manufactured to GM OE tolerances for consistent readings

What vehicles and systems is the 15326386 sensor compatible with?

This GM Genuine Parts sensor is vehicle-specific and intended as a direct replacement for the original factory component in compatible GM models. Check your vehicle’s parts catalog or VIN lookup to confirm fitment before purchase to ensure proper electrical and mechanical compatibility.

• Designed to replace the original factory temperature sensor on select GM vehicles
• Fits systems that use a multi-purpose coolant temperature input
• Typical applications include radiator fan control and dashboard temperature gauges
• Refer to GM parts reference or dealer lookup for exact fitment

How reliable and durable is this GM original equipment sensor?

GM Genuine Parts are produced to meet the same specifications used during vehicle manufacture, so this sensor offers the fit, form, and long-term durability expected of OE components. Materials and assembly processes are selected to withstand engine bay conditions such as vibration, heat cycles, and coolant exposure.

• Built to GM original-equipment performance standards
• Materials chosen for corrosion and temperature resistance
• Quality control to maintain service life comparable to the factory part
• OEM connector and thread size for secure installation

How do I install or replace the temperature sensor safely?

Replacing the sensor is typically straightforward but vehicle-dependent; it often requires draining a small amount of coolant and removing the old sensor from the engine block or coolant housing. Always follow the vehicle service manual for torque specifications, proper sealing techniques, and system bleeding procedures after installation.

• Disconnect battery and relieve cooling system pressure before removal
• Drain coolant as needed and use correct thread sealant if specified
• Tighten to manufacturer torque to avoid leaks or damage
• Refill and bleed cooling system, then verify sensor readings

Who is this for? The GM Genuine Parts 213-928 (15326386) sensor is aimed at vehicle owners, independent mechanics, and repair shops seeking an exact-fit replacement for a GM factory temperature sensor. If you need dependable, OE-quality temperature readings for coolant control, radiator fan activation, or dashboard temperature indication—especially on GM vehicles that list 15326386 or 213-928 as the OEM part—this sensor offers a direct-fit option engineered to GM standards.
