D 2008/2009 Cooling system W 09-08-01 z Heat up the coolant thermostat in the water bath. In order to determine the exact beginning of opening, the temperature should be measured as close as possible to the ther- mostat without touching it. The water should be continuously stirred for an even temperature distribution. The temperature rise should not take place faster than 1°C/min. Otherwise the begin- ning of opening will be delayed accordin- gly. 6 © 41123-0 z Measure dimension "b" on the coolant thermostat. „b“ = end of stroke at 99 °C - 102 °C Stroke distance at given temperature at least 8 mm. b © 41122-0 z Install the coolant thermostat.
