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.

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.

z Install the coolant thermostat.
