I rented a 10' truck and dolly, picked up the car, and tried to get the seller to tell me what exactly led him to disconnecting the sensor, but he said he couldn't find it, and would link it if he located it later.
I was planning on taking it straight to Crazy J's anyway, but I wanted to give him as much information as possible.
I just wanted to stop at the first big parking lot past his shop, but I was further than Mom's house before I found anything, so I drove home, parked the truck in front of the 2000, and carefully drove to the garage while watching the gauges.
The temperature seemed under control, but when I got there the radiator was low, and the oil cap was milky.
We will see what Crazy J says, and when I will hear back.
