the average cost to replace an engine in a ford ranger

Somewhat of a difficult answer to accurately give - being that your area dictates labor rate, and the shop you use could vary in the time. Plus, do you want to use a remanufactured engine or a used engine? All those prices may vary. Is it 4x4? Automatic or manual transmission? With questions to ask, I would ball-park an estimate for a used engine to be installed in your truck at about $3,000 parts and labor.
