Keep your engine's cooling fan cycling on cue with the Standard Ignition switch TS-386 (also written TS386), an engine cooling fan temperature switch that reads coolant temperature and closes an electrical contact to signal the fan controller. It installs as a direct-fit replacement across a range of Audi and Volkswagen applications, including the 1989-1991 Audi 100, the 1988-1992 Audi 80, the 1985-1988 Audi 5000, the 1981-1987 Audi Coupe, and the 1987-1988 Volkswagen Quantum, plus the matching Quattro variants — see the Buyer's Guide tab for the full list and engine details.
Thermal actuation: a custom wax formulation expands when heated to trip a snap-action contact and transfer the electrical signal to the fan controller.
Calibrated set point: every unit is factory-calibrated and tested to make electrical contact at its specified lower-temperature set point.
Bimetallic contact arm: a formed bimetallic arm uses the differing expansion rates of two fused metals as a creep-action device for precise operation.
Built for service: robust design and high-grade materials meet the demands of professional repair.
If a failed cooling fan switch is the cause of an overheating engine or a fan that won't cycle, this replaces the original switch. Diagnose the cause before replacing.
It's an engine cooling fan temperature switch that senses coolant temperature and closes an electrical contact at a calibrated set point to signal the fan controller.
Which vehicles does the TS-386 fit?
It fits applications such as the 1989-1991 Audi 100, 1988-1992 Audi 80, 1985-1988 Audi 5000, 1981-1987 Audi Coupe, and 1987-1988 Volkswagen Quantum. See the Buyer's Guide tab for the full list.
How does this switch operate?
A custom wax formulation expands when heated to trip a snap-action contact, and a formed bimetallic contact arm provides precise creep-action movement to transfer the signal.
Is each unit tested?
Yes. Every unit is factory-calibrated and tested to confirm it makes electrical contact at its specified lower-temperature set point.
My fan won't turn on — will this fix it?
If a failed cooling fan switch is the cause, replacing it with the TS-386 replaces that switch in the circuit. A fan that won't cycle can have other causes, so diagnose the cause before replacing.
