Thermostat is accessed with 4 10mm bolts and the cooling system air bleed screw on top of the Tstat housing is 8mm. So a 10mm wrench and and 8mm wrench should be good

Sorry to jump in but would you mind explaining how to get the thermostat out? I tried using the manual but didn't understand

Hey Donovanhawk,

Please see the instructions for replacing thermostat below.

The first step for draining the coolant in the engine block is not necessary unless you want to replace all of the coolant in the system. These block drains are often seized in.

You will lose some coolant when changing the thermostat if you do not drain the block so you will need a catch pan and also take care not to get coolant on the drive belt.

You can reduce the amount lost when changing the thermostat by draining some from the radiator drain but without draining the block you will always lose some as the thermostat is removed.

Note the orientation of the old thermostat when removing as you need to install the new thermostat facing the right way. It also describes in the instructions an arrow marked on the thermostat for where the vent hole should be.

Hope that helps, any further questions please don't hesitate to ask.

Regards, Joe
