Removing thermostat Smart Fortwo 800cc diesel

[@yuidfbse]

Great video thank you very much! One question, do you know where the coolant bleed valve/plug is on the engine? I did a cooling flush but could not find the bleed point location that I know should be near the cylinder head to bleed the air out of the tubing. Now the car is overheating with a water not circulating, and I've searched all over the Internet and the all the information available is only for the gasoline engine not the diesel. Thank you very much😊😊😊

Hi! Thanks for the video, what method have you used to have more space to work on the thermostat?

If I good remember I released engine frame, let it go down a bit, it is easy

Mine stays at 2 dots. Normal temp is 3?

@@alessandrosega1508 yes normal should be 3, there are posts about this exact issue (that is extremely common in diesel smart cars) on clubsmartcar, is the thermostat that for a design issue doesnt fully close and always let a tiny bit of hot coolant into the radiator not allowing to reach operating temperature, you could either place a restrictor plug that create counter pressure allowing the thermostat to seal or i have fitted a petrol smart car thermostat that is designed with a restrictor already built in, you can read about that on clubsmartcar, the only issue is that with both options you need to lower the engine to reach the thermostat so is not a 30 minutes job, If you make that mod I also suggest to block the egr, in the long run the engine will thank you and will stay cleaner
