2011 cruze ltz
I’ve notice my temperature fluctuate while im driving on the highway. It’ll reach its operating temperature, then dip down to about a quarter cooler then back up to operating. It’ll do that a few times then itll eventually stay at operating temperature.
I figured it was a thermostat issue but i recall reading somewhere that it shouldnt be replaced unless theres a check engine light for it.
Also, ive been getting the p0299 code, low turbo boost pressure. Ive done a pressure test and it seems to be leak free. Could it be the sensor? Maybe the turbine is gone??
