Standard Ignition FLS-15 Engine Coolant Level Sensor

Engine Coolant Level Sensor for GM Applications

Standard Ignition FLS-15 is an engine coolant level sensor built for direct replacement service on select GM vehicles. It uses a female plug-in connector, 3 blade terminals, and 12-volt electrical architecture to support accurate coolant level monitoring in the reservoir or tank circuit.

Fits 1994-1996 Oldsmobile 98, N/A; Fits 1994-1995 Buick LeSabre, N/A; Fits 1994-1995 Buick Park Avenue, N/A; Fits 1995 Buick Riviera, N/A; Fits 1994-1995 Oldsmobile 88, N/A; Fits 1994-1995 Pontiac Bonneville, N/A.

Key Features

• Engine coolant level sensor for cooling system monitoring
• Female connector with plug-in design for straightforward electrical connection
• 3 blade terminals with male terminal gender
• 12-volt electrical specification
• Built with copper alloy conductors for strong electrical conductivity and reduced resistance
• 100% tested for mechanical switching and electrical switching performance

Detailed Description

Standard Ignition FLS-15 is engineered for service replacement where reliable coolant level detection is required. The robust construction and high-grade materials support consistent operation in demanding underhood conditions, while the copper alloy conductor design helps maintain stable signal transfer. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Vehicle-specific fitment includes 1994-1996 Oldsmobile 98, 1994-1995 Buick LeSabre, 1994-1995 Buick Park Avenue, 1995 Buick Riviera, 1994-1995 Oldsmobile 88, and 1994-1995 Pontiac Bonneville. If you are replacing a coolant level sensor on these Buick, Oldsmobile, or Pontiac models, FLS-15 provides a direct-match service part reference.

Common Problems It Can Address

• Inaccurate coolant level warning readings
• Intermittent low coolant indicator operation
• Electrical switching faults in the reservoir sensor circuit
• Corrosion-related signal loss at the connector or terminals
• Replacement needs after sensor wear or internal failure

Installation Notes and Tips

Verify connector style, terminal count, and voltage specification before installation. Inspect the coolant reservoir or tank connection point for contamination, damaged terminals, or coolant residue that could affect sensor performance. Confirm the replacement matches the original FLS-15 application and the vehicle’s exact year and model before service.

Quality Assurance

Standard Ignition backs this coolant level sensor with a design approach focused on technician needs, using durable materials and validated electrical and mechanical switching performance. Each unit is tested to confirm function before release.
