Important points for diesel drivers at low temperatures!

Is it against minus 20 degrees, which, as we have just learned, can also prevail in Germany in the winter months, then can at Diesel vehicles absolutely Problems occur. You are not always with the so-called Winter diesel on the safe side and the car is protected. As already at minus 7 degrees in the diesel Paraffin crystals begin to form, it is easily possible that Fuel system and Fuel Filter clog. The winter diesel promises a remedy in this regard to minus 20 degrees. Unfortunately, the reality is mostly very different when you consider that crystals form before the -20 degrees mark. That can mean costly damage, among other things Injectors come to harm. Because of this, some vehicle manufacturers have their own Heating systems built in to avoid such frost damage. Unfortunately, the technical equipment also often fails at very low temperatures.

Problems with freezing cold - why?

Paraffin ensure clean diesel combustion and good Lubricating properties. If the temperatures drop too much, however, paraffins will form crystals and clump together. Also called Gelling or Flocculation from the fuel. These lumps get stuck in the fuel filter, enlarged lumps in turn clog nozzles and lines. For this reason, diesel are specially effective in winter additives present, which should exclude clumping.

Offer frost-proof protection

The best course of action in this regard is one heated garage, the diesel will remain fluid there. But also one unheated garage or sheltered place are not to be despised. This is often enough to have temperatures 10 to 15 degrees higher than outside without protection.

Another possibility to make the diesel more resistant to frost is to add Additives. Special additives are added to ensure that winter diesel retains its liquid properties as much as possible. The easiest method is Petrol add, however, the protection is only marginal and the Lubricity also leaves a lot to be desired. Modern additives are manufactured in such a way that they can be easily applied. Mostly they are products like one Diesel cold protection as a ERC diesel cold protection or a ERC diesel additive. These are resources that are already available in winter diesel anyway. But in smaller quantities. A further supply of such antifreeze can increase the freezing point further, feasible up to 30 degrees minus. But you always have to focus on the mixing ratio pay attention to specifications.

Also a regular one Maintenance of Fuel filter is important. Water collects in the filter regularly at certain intervals, which is easy freeze can. Therefore, it should be drained regularly. Failure to do so may freeze the water and reduce the beneficial properties of the filter minimize.

What to do if you are already constipated

If the diesel is already sultry, you are too many If paraffin articles are present, the fuel system must be defrosted. The best thing to do is to park the car in a workshop and at Room temperature. But don't drive, but tow away to let. As soon as the entire system is warmed up again, the diesel can flow again. In this case, the used fuel filter should definitely through replaced a new filter .

Mistakes to Avoid

Incidentally, you should never do the whole thing with one Foehn try to thaw. Anyone who tries to defrost lines and nozzles with a hair dryer or even a heat gun is at risk a fire trigger. If it's a new car, then you should never add gasoline. This was common practice with older models, but it should definitely be with modern vehicles avoided become. High-performance and technically modern cars are special sensitive and at worst it could be irreparable engine failure arise.

When in doubt, always that Experts ask to be on the safe side. The use of a car repair shop costs, but is the best in the long run cheaper method. An irreparable one engine failure is much more expensive than an inspection in the workshop. It is therefore advisable to have a car before the cold season winterproof to have it done. Thereby both the fuel and all other liquids Made frost-proof.
