== General ==
The thermostat is a valve that opens and closes based on a specific temperature. 
Once it starts to open it will allow more engine coolant fluid to pass through it and into the cooling system. 
This ensures an increased flow of engine coolant fluid in the cooling system as the temperature inside the engine increases. 
 
The OEM thermostat starts to open at 78C (172F) and will be fully opened at 90C (194F). 
With the OEM ECU the radiator fans are set to turn on at 91C (196F).

== Thermostat recommendations ==
See: [[Thermostat#Recommendations|Thermostat recommendations]]

== Normal operating temperatures ==
See: [[Changing_engine_coolant#Normal_operating_temperatures|Engine coolant - Normal operating temperatures]]

== Required tools ==
* Ratchet
* 10mm ratchet socket
* Several different ratchet extensions
* Oil/Fluid catch pan
* Towels
* Floor jack + 2 jack stands

== How to change the thermostat ==
=== Pre-conditions and jacking up the car ===
* Make sure that the engine is cold. Never open the cooling system when the engine is hot.
* Put the car in the first gear and set the parking brake.
* Jack up the car on the front by using the central jacking point near the engine.
* There are two front-jacking-points on each side. Place one jack stand on each side at the jacking-point that is the furthest away from the front wheel.
* Lower and remove your floor jack (or keep it in place for extra safety)

=== Removing the thermostat ===
The workshop manual describes a relatively complicated way of removing the thermostat. 
There is a much simpler way that let's us remove the the thermostat within 15 minutes. Only two bolts are required to be removed.
* There are two thick black hoses connected to the radiator.
* The lower radiator hose connects on one end to the radiator and on the other end to the engine.
* You will need to remove the radiator hose from the engine as the thermostat sits between the hose and the engine.
 
* Get under the car and search for the lower radiator hose that connects to the engine.
* Follow the hose until the end point that connect to the engine.
* The hose is hold in place with a clamp mounted on the thermostat cover.
* There is no need to remove that clamp as we will remove the hose together with the thermostat cover.
* The thermostat cover it mounted with 2x 10mm bolts onto the engine.
* You should reach both bolts very easily from under the car.
* Loosen the bolts but to not remove them completely yet.
* As soon as you remove the thermostat cover, a significant amount of engine coolant fluid will leak out of it.
* So make sure that your face is out of the way and that you have your oil/fluid catch pan placed below it.
* Remove the two bolts completely and remove the thermostat cover slowly as the thermostat is hold in place only by the cover.
* Once the thermostat cover is removed you should either have the thermostat already falling down or it might be still stuck on the engine or inside the thermostat cover.
* Simply pull it off.
* Clean the thermostat cover, engine port and the area around it.

=== Testing your thermostat ===
* Before installing the new thermostat it might be a good idea to test if it actually works.
* You can do this by putting it inside cooking pot with water. Heat the water until it start to boil.
* You should now see how the thermostat opens
