Hey , first post on here but my z keeps running at low temps. I just replaced my thermostat due to the old one sticking open and causing the same problem. I ended up doing my water pump and chains too during that job but I’m still seeing low temps while driving. Car reaches operating temp when idle and can run without any problems until I start driving. Maybe thermostat still sticking open?also had a difficult time bleeding. It was colder when I brought it out and I had no front bumper but I wouldn’t think that would cause it to get that low at all Thank u!
