Drill the expansion body (2) in a centered way with a drill Ø 4.2 mm.
Drill only the housing, take care to not drill deeper:
otherwise, the adjustment device will be damaged.
2
Heat the expansion body (2) with a thermal blower until the wax drips in the hole.
3
Make a thread M5 in the hole.
4
Measure the basic dimension (a).
5
Screw the bolt (3) in the thread.
6
By screwing the bolt (3), open the coolant thermostat (1), until the adjustment dimension (b) is reached.
The adjustment dimension (b) is calculated with basic the dimension (a) + 7 mm. Calculation example with a basic dimension (a) of 2 mm: 2 mm + 7 mm = adjustment dimension (b) 9 mm.
