• Radiator fan cycling problems
• Overheating caused by failed fan switch operation
• Intermittent electric fan engagement
• Restoration of original radiator-mounted cooling control on Volvo applications

Installation Notes and Tips

Verify the radiator-mounted switch location and connector style before installation. This TS-266 uses a male round connector and blade terminals, so the mating harness must match the original configuration. Confirm the vehicle’s year, model, and radiator switch style, especially on 740, 760, and 780 applications where notes indicate threaded or push-in variations.

Quality Assurance

Standard Ignition supplies replacement electrical components for service applications, and TS-266 is built to match the listed fitment and connector specifications for the covered Volvo models.
