First I drained the radiator from the draincock at the bottom of the radiator. Next, I disconnected the air intake rubber boot at the side opposite the throttle body where it connects to the long metal tubing. I loosened the clamp at the throttle body and rotated the boot up out of the way. Remove the upper radiator hose completely and get it out of the way. Now if you have the right tools you can push the hoses around between the throttle body and the thermostat housing and gain access to the two bolts which secure the housing. The rest is obvious. One tip, when you replace you t-stat with an 82 deg. one it will keep you temp dopwn to about center scale on the dash temp gauge when the car is moving but you may notice that the engine temp rises everytime you come to a stoplight. You also need to change the electric fan switch which is screwed into the lower part of the radiator, (conveniently located right in front of the turbocharger). The OEM switch turns the fan on (low speed) at 92 degs. This is obviously too high since it is hard to cool 82 degree block with 92 degree water. I got an 82 degree one from TheSaabNetwork.com website which was sent to me by Townsend Imports. I wish it came on even lower say 78 dgrees or so. Afterall, that is only regulating the temperature of the coolant in the radiator. It's the t-stat that regulates the block temp. -Fred Wills
