Part 1: Diesel Buyer Beware - Engine Overheating and Coolant Loss Problems - On Demand Video

Start with the basics to determine the source of the problem

If your engine is just running hot, it may be due to a plugged radiator or possibly a stuck thermostat. If your engine is just losing coolant it could be a leak in the water pump, radiator or hoses. But, if an engine is running hot and losing coolant at the same time, it is a good indication there could be a serious problem and it should be checked into right away. Just don't keep driving the car or you can ruin the engine.
