Should I Bother Replacing Temp. Switch?

[omri617 18]

The fan gets into action when temp is 70 .

I did a little research and found out that 90 is the optimal working temp. for 1.9 8V .

Should I bother replacing for another unit (Switch) that corrects that?

Are you going by the temp marked on the gauge or are you using an accurate thermometer?

My main concern is that the fan is almost running all the time. I should be bothered that it never reaches 90?

 

 

 

Is it overheating?

Take the switch out and see what number is stamped on it. This will relate to the on/off temp.

O.K i see..

When taking out , water will drain from the hole?

should I bleed the system afterwards?

Thanks Simon

Definitely bin it.

 

The normal working temperature of an engine is set by two things

 

The thermostat sets the lower end - if the coolant's too cool, the 'stat closes and the coolant warms up by being isolated from the rad.

The fan switch sets the upper end - if the coolant's too hot, the fan kicks in to blow air over the rad and help it cool the coolant.

 

The fan switch temp needs to be a chunk north of the 'stat temp - otherwise, you'll just have the 'stat opening and closing all the time, as cold water comes in to a hot engine.

 

If the 'stat opens at too low a temp, then you'll increase engine wear and fuel consumption, and decrease the heater output.

 

Obviously, if either's too high a temp, you're going to overheat the engine.

So what you recommend me to do?
