Normal cylinder head temperature mustang. 49 c c mark 60 c normal band start. Just had no idea what the cht should be. Degc display of engine temperature in degrees c input from cylinder head temperature sensor. 210 220 fahrenheit so around 20 30 degrees above engine temperature and also showing higher figures earlier in the warm up process than engine temperature gauge engine coolant temperature gauge located under tachometer usually vertical as far as i remember. Coolant exits the engine at the coolant neck on top and flows back to both the radiator and a return to the engine at the y pipe. Double check theres no air inside the coolant jacket.
Cylinder head temperature. Dont worry i once saw 225 while idling and everything was fine. I see temps for the head as high as 223 fahrenheit in my mustang although it usually stays between 185 and 209 fahrenheit most of the time. The coolant temp was well within normal operating limits and the cht did drop back around 198 or so when i left. Also does the heat affect the turbo more as in does it hinder it. If not then straight up temperature is ok.
I also found this on the web regarding the cht. Not from the coolant temperature sensor. Coolant enters the engine at the left hand driver cylinder head at the thermostat and reaches exhaust valves on both heads first before flowing into the rest of the engine. That sounds completely normal. Soooooooo the temperature as reported by the pcm is from the cylinder head temperature sensor. The general rule for cylinder head temp is that it is around 10 15 degrees hotter than coolant temp which puts your coolant around 195 200 which is just right.
Was just wondering why there were no color indicators like on the oil temp guage. 223 degrees is a little elevated but that can happen when you have higher ambient temps.
