Buying a used engine

Be careful when buying a used diesel. Diesel engines operate for a long time, but that does not mean that you should not explore all the places traditionally wear. On some engines very easy to disguise as the duration of operation and wear. In assessing the state of the engine there is a danger "lopuhnutsya" if you are not familiar in diesel engines.

As with gasoline engines, the exhaust of a diesel engine to be smokeless. Moreover, should not emit smoke from the open mouth of the tube filler in a warm engine. Because the diesel engine has larger noise than gasoline engines, you have to distinguish between the operating noise of the rushing worn pistons, connecting rods, camshaft, etc. If you have any doubts about the condition of the engine, then seek professional help.

Turbodiesels are very popular as turbo fits in well with the characteristics of a diesel engine. Turbochargers operate with a small boost pressure and at low engine speeds, which gives them longer than the lifetime of gasoline engines. Turbodiesels excellent for trucks and multi-ton trucks.

However, diesel automatic devices it is difficult to meet the demands of an automatic transmission for flat torque characteristics. Few manufacturers are concerned about this problem. Among them, Citroen, Mercedes, Peugeot and recently joined them Opel, but they used automatic transmissions only on the machines of the middle class.

Due to the growing popularity of all, diesel is no longer seen as the poor relation, and the level of its finish, they fully comply with their gasoline brethren.

When buying, pay attention to the residual value of the diesel engine. At the time, diesel cars boosted car sales in Germany, but the peak of sales was reached four years ago up to the present time there is a gradual decline, so make sure you do not overpay for the honor of becoming the owner of a diesel car.

Check the mileage. Diesel cars are bought because of their potentially high reliability and high mileage. Especially when they are bought new. But this does not mean that you should not pay attention to the odometer. Indeed, many traders do not like to deal with cars, the mileage of which exceeded 80 thousand. Km and, accordingly, the price is adjusted to them. Or, without further ado, just reset the mileage on the meter. Mileage 160 thousand. Km is quite natural for the well-served by a diesel engine, but think twice if the counter shows 320 thousand. Km or, especially if it is second-hand taxis with mileage.

Except for the motor, the majority of diesel cars in structure identical to their gasoline brethren, the same applies to the suspension, brakes, but consider the prices of spare parts. For example, the exhaust system are long, but different from those of gasoline engines. And if you're used to buying parts from parser damaged cars, keep in mind that the details of petrol engines may be superficially similar and suitable in size, but the engine block of a diesel engine differs from a similar block petrol engine and in most cases can not be selected as a replacement . Also, different gear ratios and clutch transmissions.
