Works good, everything was included to install it in my cj5. It seems a little slow to start reading from cold, but from what I understand about this kind of gauge it’s not uncommon or unusual. Once the engine has some heat and it’s reading it’s accurate. I can watch it open right at 180 degrees and fluctuate between 180-170, which tells me both my thermostat is working and this gauge reads correctly.My only small complaint is the faceplate and needle inside are set back into the housing pretty far, you’ll want to make sure wherever it’s mounted you can look fairly straight into it. But it’s not too big an issue for me.Overall happy with it.
