1997 Professional Chassis Raised Roof Presidential Limousine
I just bought this car at an auction. The low coolant message light was on so I added about 3 quarts of water to the overflow tank. Let it idle a few minutes and saw no leaks so I decided to drive it 15 miles home. Had the coolant temperature in the display just to monitor things. Air temp was about 93F and on the highway it showed a steady 196F coolant temp. Once I got into stop and go traffic, it went up to 208F, then 213F, and finally 223F when I got home. Also, as I stopped at lights, the oil lamp would flicker on and off unless I put it in neutral. Once the STOP ENGINE message came on for low oil pressure. How much of this is normal in this heat? I don't know what weight oil it has now but how high can you go? 20W-50?
