Troubleshooting Radiator Fan not coming on

Post by Lostnomad1 »



Morning GWers,

My fan came on my 1200 Aspencade prior to me doing a double radiator flush. Distilled water and replaced with non-silicate coolant. The levels seem good but the fan won't come on and I can't tell if the coolant is flowing through.

I tested the fan by removing cap and grounding, it works. (Last resort toggle switch)
The pump gets hot so does the return
Fuses are all in good order

Im starting to think that its my pump, how can I test this to ensure I replace the correct part?
