I'm about to change the water pump on a 95 S 500. I plan on replacing the thermostat, idler pulley (bad), drive belt, and flush. I've never done work on this car so I'm interested in any hidden problems with this repair. I see a hex head adjust between the water pump and pwr steering pump and it looks difficult getting to the water pump bolts. Any input on this operating would be greatly appreciated. Thanks.
