I Have a 2000 Ford. Ranger XLT 4.0L OHV and when I bought it at the auction it has 40,000 miles. I was just looking at it the other day.. you know checking the fluids and stuff (it has not been driven yet) and noticed that the antifreeze reservoir was dry. I put antifreeze in it and started it up and let it heat up. The temperature was perfect and did not overheat at all. But the thing is is I do not see where it is leaking from. Also I could not smell any Antifreeze burning. and the engine sounds fine. Please help
