How did you figure out it the thermostat stuck?.....I bought a 2012 commander 1000 x on friday afternoon. Saturday morning after putting two (2) hours on it the thermostat stuck closed and it over heated . talk about not happy. :furious:
Good to know how to look for that problem if it ever comes up for me.When it was over heating i grabbed the t-stat housing and it was hot on the top side which goes to the fill neck and cylinder heads and the bottom side which goes to the radiator was super cold the left side of the rad was hot and the right was cold. so that told me its not circulating the water.
On each head at the coolant housings will be a screw....with the engine running, loosen each up a bit and let the air spurt out...when coolant runs, tighten back up...this eliminates steam pockets in the upper cylinder which contributes to several maladiesI'm thinking my T-stat isn't working correctly as well. How do you purge the system of air i would like to try that before i take it back to my dealer
