7.4 Thermostat core inspection
Check the opening temperature, full opening temperature and lift of the main valve in the
thermostatic heating equipment with adjustable temperature. If one of them does not meet the
specified value, it should be replaced. Or use a thermometer, water, heater, and container to test.
The initial opening temperature of the thermostat is 80
～
84 ℃ (176
～
183 F), and the core moving
0.1mm (0.004 in) can be regarded as the initial opening. The full opening temperature is 95°C (203 F),
and the core movement is greater than 3.5mm (0.14 in).
The simple test method is to put the core body into a high temperature resistant container, pour it
into boiling water and soak for a period of time, take out the core body with pliers, and observe
whether the valve can be fully opened. Until all closed.
The joint surface should be cleaned before rematching, and no O-ring should be installed.
8. Water pipe
Check whether there are cracks, bulges and other defects on the surface of each water pipe. Block one end of the water pipe,
ventilate the other end and put the water pipe into the nozzle to check if there is any air bubbles, if any, replace it.
9. Check the water pump cover assembly(M310)
Check the two points indicated by the arrows for leakage. The bolts are for cooling liquid bolts. If there is leakage, remove the
bolts and replace the O-ring. If there is leakage at the leaking pipe of the right crankcase cover, you can try to remove the
leaking pipe (because the sealant is applied before press-fitting, it is difficult to pull out), clean it up, reapply the sealant and
reinstall it; or directly replace the right crankshaft Box cover assembly.
A small amount of coolant leaking from the leaking pipe is normal. If the engine is running continuously, it is abnormal. The
water pump cover needs to be disassembled to check whether the seal has failed.
