okay, so maybe this isn't such a huge deal, but it made me pretty happy.... i have a manual switch for the cooling fan in my 90' Buick LeSabre, (aftermarket, redneck mod to replace bad relay switch) i had left it running in the parkinglot of my place of work so that it would warm up. I forgot about it, and left it running for an hour without the fan on. when i came out, i noticed that there was more steam the car to be seen. i promptly shut it off, but not without noticing how she was still running like normal with no signs of any problems. there was coolant all over the ground that had leaked out of the resivor overflow cap. i turned the key on, and let the fan run w/o the engine for about 3 minutes, the i start it again and drive the two miles home (and i was far from milking it) she ran great the whole way and acted as if nothing was wrong at all... she has 231,688 miles on the odo. I LOVE BUICK 3.8's!!!!!!!!!
