Radiator fan tempature?

sluflyer06 · 06-18-2013, 08:32 AM

Just got my car back from a dead coolant pump.

When should radiator fan kick on?

Don't know precisely for this car, but generally only after your coolant is up to temperature (~170F or so) and the car is either stationary or moving very slowly (like <20mph).

I just went out for a sanity check in the parking lot at work. I honestly swear that pre-pump failure the car held 200F (93C) on the money during all driving/idle conditions.

Since replacing the pump and therm. yesterday it seems to be going through the different cooling modes as intended (ECO, High, High+, etc). Also the aux fan (or feels like one) seems to kick on long before the main fan (is there a aux fan?) and then the car finally settled out at 108C and held it perfect with main radiator fan running.

Guess all is well.

My coolan temp stays almost exactly at 210*F under all driving conditions, according to my gauge hijack.
