Peugeot 406 D9 EW10 Thermostat And Gearbox Vibrating by pafek(m): 11:29am On Sep 24, 2017
I wish to restore back my dad 406 D9 EW10 thermostat. the old thermostat was faulty thus it was removed instead of replaced thereby connecting d fan to start spinning immediately d car is started.
2ndly I noticed the gearbox makes a vibrating noise when d car is started but stop when the clutch is pressed. the mechanic said d gearbox need to be changed..., am not okay with his insertion considering it's the follow-come gearbox.
the 406 is 6years old not having any issue except the gearbox and ofcos the thermostat.

How did they come to the conclusion the thermostat was bad?

I was told temperature was high, fan wasn't spinning, there was water in d reservoir. was told they checked they water pump n was also working. and that when they removed the thermostat, temperature went back to normal.

your thermostat is like a tap head, it allows water to flow or not to flow.the only way to determine if it is faulty is to remove it and throw it into a boiling pot of water.You will see it physically open when the water starts boiling @ 100 deg.
Any mechanic who tells you to remove waht came with your car and by pass it is a quack,run away.
Your fan is controled by a sensor that read teh temperature iether from the radiator and Engine, so if Engine is hot and fan refuses to come on then your coolant temp sensor is dead as this picks up readings after your thermostat allows hot water to flow past it.

physically you cannot tell as its a mechanical device, the only way is shoving it into boiling water.so buy one, take it home, boil a pot of water and put it inside watch closely
