Please help ok . So first thank you for adding me to group i own 2011 limited 300. Recently it developed a issue with running hot . So things i hav e done .new radiator, water pump, thermostat an housing, oil cooler ,,coolant sensor, plugs,blet,. Am i missing something . And caps . I burp it on ramps run till warm then cap it .i squeeze the lines get out bubbles. .after i burp it it comes up to temp right around 204then drops 196 . I drive it gets to 208 then drops 196. About half hour of driveing temp spikes 220,230,240,an so on i shut it down around 250 befoe red light comes on . What am i missing .i bore scopped cylinders didnt see anything out of normal. No smoke no coolant in oil an vise versa .i know the actuator is bad could that be the cause ????please any info would be greatly appreciated

 

Holy Cow. Seems like you have done all the right things. Given all the things you have done one hardly knows where to start. If I had to guess on what you are missing I would go with water pump and/or thermostat.

 

Thanks i have changed all the above . I pressure tested the coolant system an it has a very light drop . So i am not so sure what it is . It drops 1/4 pound in 2 hours .cant hear or see any visible leaks .i covered e every square in of motor an lines with some really bubbly solubtion can fi n d abythugsmm

 

Has the radiator cap itself been replaced? May be obvious but must ask.
