Standard Ignition S2510 Engine Coolant Temperature Sending Unit Switch Connector

Engine Coolant Temperature Connector

Standard Ignition S2510 is a direct replacement engine coolant temperature sending unit switch connector for repairing damaged sensor wiring without replacing the full harness. It uses a male oval housing with two female blade terminals and two-wire construction for a clean electrical connection in demanding underhood conditions.

Key Features

• Direct replacement electrical connector for engine coolant temperature sending unit switch circuits
• Male connector gender with oval housing for OE-style sensor connection
• Two female blade terminals and two-wire layout
• Housing made from polyamide resin for durability in harsh environments
• Terminals use high-grade copper alloy, brass, and phosphor bronze materials
• Protective tubing included for added wire protection at the repair point
• 100% tested for mechanical and electrical fit, form, and function

Detailed Description

The Standard Ignition S2510 is built for technicians and DIY repairs where the original coolant temperature connector is heat-damaged, corroded, or broken. It replaces only the connector at the sensor end, helping restore a secure electrical interface for accurate coolant temperature signal transfer. This part cross-references EC2421 and PT2495 for the same application. For vehicle-specific service work, it is a practical choice when servicing Ford, Honda, or GM coolant temperature connector repairs that require an oval two-terminal plug.

Common Repair Uses

• Broken or cracked coolant temperature sensor connector housing
• Corroded terminals causing intermittent temperature signal loss
• Heat-related connector damage near the engine
• Loose terminal fit at the engine coolant temperature sending unit switch
• Wiring repair where the harness does not need full replacement

Installation Notes and Tips

Verify terminal orientation and wire routing before splicing the connector into the existing circuit. Match the two-wire layout to the original sensor connector and inspect the mating terminals for corrosion or heat damage before installation. Confirm the replacement connector seats fully on the engine coolant temperature sending unit switch and that the repaired wiring is secured away from exhaust heat and moving components.

Quality Assurance

Standard Ignition tests these electrical connectors for proper mechanical and electrical fit, form, and function. The use of high-grade terminal materials and polyamide housing supports reliable performance in harsh underhood environments.
