Cooling Fan High Speed Temperature Switch

[Nigel]

For anybody interested, Ron Francis Wiring sells a direct replacement bolt in stock type connector temperature switch P/N AR-34, advertised on 200F off 185F. I installed one and it repeatedly turns on just before 190F and turns off at 182F based on watching the scan master.

Hypertech makes them as well available at Summitt with a different temp. on/off. Same settings as low speed in some chips.
