Thermostat

[paul.h]

Depending on the engine, the thermostat should start to open between 80 and 90°C, so the radiator top hose should not start to get warm until the engine is hot. If the hose warms up as the engine warms up then the thermostat needs replacing.

When the thermostat is open, if you squeeze the top hose and rev the engine you should feel the hose pulsing. If when the engine is cold you can feel the top hose pulsing, then it is likely, as Paul stated above, that the thermostat is stuck open.

 

The thermostat not only opens when the engine is warm, it is also constantly opening and closing slightly during operation to maintain a constant system temperature. That constant sytem temperature maintains the perfect combustion conditions, if the thermostat is stuck open then combustion is not optimal and you will be using more fuel.

If you have a local Motor parts direct or in fact any of the motor factors will supply a suitable thermostat, no need for genuine as I think the genuine ones are probably made by the same people who supply the motor factors.
