LT thermostatic valve
19.4.2.1 Maintenance
Normally, no service is required. Too low water temperature
depends on a defective thermostat, too high temperature may
depend on a defective thermostat, leaking O-rings, although, in
most cases, it depends on a dirty central cooler.
During normal overhaul, i.e. when changing the thermostat
element, there is no need to remove the control- cylinder (5) or
piston (6).
1 Drain the cooling water circuit.
2 Release the spring force
by opening the adjusting screw
(13), see Fig 19-5.
3 Remove the cover (11)
by opening the screws (12).
4 Remove the plug (1)
and push the control piston (6)
against the spring force until the retainer ring (2) can be
removed.
5 Remove the element holder (7)
with element, springs
(4) and washer (3).
6 Remove the control piston (6)
with the control cylinder
(5). Use extractor tools 800131 and 800063.
7 Remove the retainer ring (9)
and the thermostat ele-
ment (8).
