What should I look at when buying a Used Diesel vehicle?
One of the main things would be to make sure the engine will start cold, this is better to test in the winter when the temperature is cooler. You are looking for the engine to start the first time, unless it is below 40 then it may take the second crank if it is a higher mileage engine. This is testing multiple things, if the injectors have wear it will take longer to crank, also the glow plug system (if the engine is equipped with one) You want to check by opening the hood and touching the coolant hose to test if the vehicle is cold and has not be started that day or has been sitting for at least 4 + hrs.
There are other things to look at and we do test on diesels for you so you have more of an idea of what you are buying.
