Volvo 850/960 fan, JY, $12

I'll take a 15 year old OE fan over any aftermarket fan made in China in the last 3 years. Run it on the factory circuit for the aux fan (you can remove the aux fan) and replace the radiator temp switch with a colder one from a 318ti.

The only thing I had to do was trim one side of the shroud to make it fit our small radiator (height is the same) and later I used a strip of aluminum to cover up that big fat gap you can see on the left side of the radiator. I lived with that gap for about 1 year after this pic was taken without any issues though. The fan is used to cool cars that make up to 250hp in stock form, so its more than enough cooling power for our little 1.8. A few other guys on the board are using the exact same setup and I'm sure they'll chime in.

cheers
