I would take a rubbing of this test well cap but it's in Owingsville, on the other end of Kentucky. I pulled in there when I noticed my engine had overheated-the temperature gauge was as high as it could get. Turns out hubby never puts antifreeze in his car. There were a clutch of gas stations, dollar stores and snack shops there. Good thing I looked up rex cool on the phone before I filled the reservoir. The trouble could have been so much worse. After cooling down, a jug of water sent me on my way.
