2) INSPECTION
Suspend the thermostat and a thermometer in
a pan of water until the thermostat opens.
It should begin to open at 82
O
C (180
O
F) and fully
open by 91
O
C (196
O
F).
(c) Installation
1. Insert the thermostat into its housing with
the bellows end downwards and install new
gasket.
2. Tighten the capscrews.
3. Work the hose back on to the thermostat
housing and tighten the hose clamps
securely.
4. Fill the radiator with clean water.
7. HOSES
Top and bottom hoses should be checked at least twice
a year for deterioration. The main thing to look for are
hardness or conversely, sponginess. In first case,
hardness leads to lack of flexibility and cracking; the
latter causing leakage and also allows the passage of
small particles of rubber into the Radiator, blocking the
cores. Sponginess leads to lining failure and eventual
rupture of the Hose.
When installing new hoses, particular attention should
be paid to the connections. If you want a first class
job, the steel pipe connections should be cleaned and
non hardening sealing compound used in conjunction
with original/good quality Hose Clips always fitted with
the Screw Heads in the most convenient position for
adjustment with the Screw Driver. All new Hoses and
their connection should be checked a couple of times
subsequent to fitting. After the Engine has been in use,
retighten all connections, as necessary.
