Fan switch temperature

[keith_h]

Does anyone know at what temperature the radiator fan switch activates on a Sierra 2.0 DOHC fuel injection engine.

Re: Fan switch temperature

I thought the standard Sierra had a viscous fan and not an electric one.
I might be wrong, and who knows what adaptations have been made.

I have subsequently found out that it has 2 electric fans, side by side, one coming in at one temperature and the second at a slightly higher temperature

Keith. The Sierra fan switches usually have the temp stamped on one of the flats on the hexagonal "nut". Else look on the inner face that contacts the coolant. Peter.
