Hi All.
I need help figuring this out...I know this has been covered many time before... but none of the previous solutions fit here...
Situation. Every few days, not all, I get a LoCOOL message on the instrument cluster and have to top off the reservoir. The distance driven can vary from 10 miles to 400 miles. I preformed a Cold Engine Test. After 5 minutes there is absolutely no pressure in the reservoir. And after the thermostat opens at full operating temp there is still no pressure in the reservoir. But driving about 10 miles pressure starts to build yet no coolant loss at this time.
For some reason the system loses coolant after being driven yet there is no signs of a leak on the ground and the engine start normally... no indication the coolant is entering the cylinders and burning off.
I was thinking I might have a crack in the reservoir but I soaped the whole thing down looking for leaks.. found none.
I am the original owner, Had the EGR deleted in 2019, Running GDE EcoTune Full torque.
