just picked up 93 montego blue. 4k on rebuild, everything is stock but has 3"downpipe for somereason. have an issue tho, when im done driving and let the car idle (4-7min) and turn the key back onto accessory the big fan kicks on... am i not letting it cool down well enough?? btw anyone out there from washington??

That's normal, and letting the car stand for 4 - 7 min is a long time unless you have been driving it hard. Also it's good if you have the chance to drive around a parking lot slowly to let the car cool down before you park. The downpipe is necessary because the pre-cat is known to clog and raise engine temps.
