So I installed a turbo (Hypermax) on my '93 7.3 IDI and that's working pretty well (need to adjust it a little because I'm only getting up to 7 psi of boost, but for now that's ok) but since I installed it I've always had the Engine Temp light turned on on my dash. I didn't think much about it because I have an aftermarket coolant gauge that works well. I had to take the truck in for some work recently though, and the mechanics pointed out that somewhere along the line of installing the turbo I pinched a coolant sensor wire which caused it to not read correctly and led to the glow plugs heating continuously. I guess they un-pinched the wire and also replaced one sensor (Duralast SU201) but told me there's one more sensor I need to replace to fix this issue, but they were out of stock at the time and I was driving across the country. The Engine Temp light is still on so I've decided to get around to replace the second sensor, but I'm not sure which one they were talking about. Would it be this one maybe Ford E8TZ-9E939-A?
