I took a 96 4x4 5speed for a test drive today and noticed the stock gagues in the dash. I notice the oil gauge went to 275? It was in the upper left corner,and ever time I shifted it went to 0 then to just over 40. What is this gauge for? Pressure or what? Also the coolant gauge in the bottom right corner went to like 120 or 130 and 90 was in the middle which is were the engine ran at. Whats the deal with that. Is it in celsius? I hope im just confused on the subject. does anyone have a picture of a dash to clear me up.
