What is under the thermostat on the top of the engen peugeot 206 . 2006 model 1.4 8 valve

You may have a cracked cylinder head or damaged head gasket.
Open the coolant bottle and rev the engine, if you see bubbles and get an exhaust has smell then you probably have trouble.
Unless you are very mechanically inclined or better yet a mechanic, it’s not recommended you try fix it yourself.
If you don’t pick up any bubbles or exhaust gas smell, you may have a blockage or even an airlock in your cooling system

no engine told, sizes or fuel it burns

Cooling fan is always on even runs when engine is cold

No valve timing marks on that one - it won't allow you to change that settings.

Follow the top radiator hose back to the engine at the bend of the hose should be the thermostat housing.Usally there is 2 bolts that mount the housing to the engine.Thermostat will be under the housing.

Follow the UPPER RADiATOR hose, in the engine side there is this iNLET where the HOSE is connected, thats the area were u could see the THERMOSTAT VALVE!

It is located in the rear under the fuel tank.You will see a black plastic cover over it.

if the car is fule injected thear will be valve that looks like an air valve on top of the engen on the fule line you can use this to bleed out the air in the line. do this with key on DO NOT RUN OR START the engen untill finished bleeding system and spiled fule is clend up and dry
