Various radiator fan schemes - Saturn Astra
The Saturn Astra had several radiator fan schemes.
Apparently, 3 different fan motors were sold. And the wiring varied a lot
I think the cars with AC and Auto transmissions had 2 fans installed. Maybe all other vairants had only 1 fan installed? I'm not 100% sure.
Check part numbers with your Chevy dealer using VIN numbers to confirm fitment.
