2015 Jeep Grand Cherokee - Overheating
I have a 2015 Jeep Grand Cherokee that is having intermittent overheating issues. I had the code for a bad thermostat in December. swapped it out with an OEM. It went out again in February. I took it to the shop and they put it a new OEM. They did not bleed the system so I took it back and had a flush done. After the flush I noticed the gauge would move a bit but never get in the area of concern. Its been about 1.5 months. I just got it where the thermostat gauge was going way up and down again. I took it back to the same shop, they looked at it and said there was an air bubble in the system so they bled it multiple times yesterday and said it seems fine now. My real question is, is this normal? or is it possible my head-gasket may have a leak?
