In order to protect yourself from problems with starting the engine in winter, it is recommended to store the diesel vehicle in the garage. However, in the middle climatic zone and in the north, such frosts occur that even this safety measure does not save the diesel engine from freezing. How to defrost a diesel engine?
Necessary
- - manual priming pump;
- - compressor;
- - blowtorch or torch;
- - screen
Instructions
Step 1
Check fuel supply. To do this, take a manual priming pump and try to pump fuel with it. If, after pressing the pump button, it very slowly returns to its original position, then the fuel receiver mesh or the fuel line is clogged with paraffin.
Step 2
Try to blow through the fuel line. To do this, remove the delivery pipe and fit the compressor hose onto it. Open the fuel tank cap and purge. Continue this process until you hear a distinctive gurgling sound. Reinstall the fuel supply pipe. Try to start the engine.
Step 3
If the engine does not start, then it is necessary to warm up the fuel. To do this, take a torch or blowtorch. Warm up the fuel tank. Make sure the manual priming pump starts pumping fuel. You should be aware that it is necessary to warm up the fuel tank with extreme caution. If you are using a torch, it is strictly forbidden to direct its flame directly to the tank. Take advantage of the screen.
Step 4
If your car does not start even after warming up the fuel tank, then it is necessary to warm up the high pressure fuel pump and fine filter. The safest way to warm up is to use hot water. On many engine models, these components are located under the intercooler. Warm up the water and gently pour it directly onto the cooler.
If your car model has free access to the fine fuel filter, then you can warm up this unit using a blowtorch or torch. All safety precautions must be observed when working with a blowtorch or torch.
Another way to solve this problem is to fill the tank with warm diesel fuel.
Step 5
In order to avoid problems with diesel freezing, it is recommended to use anti-gel additives. Also, if possible, a line and fuel heating system should be installed.
