2 Answers
Diesel vehicle frozen and unable to start can be handled by: 1. Regularly adding antifreeze; 2. Letting the car bask in the sun; 3. Using diesel with a higher freezing point; 4. Warming and thawing near the fuel tank. Methods to address difficulty starting a diesel vehicle include: 1. Preheating in low temperatures; 2. Ensuring good cylinder sealing performance; 3. Removing air from the fuel system; 4. Checking all pipelines for loose connections; 5. Disassembling and cleaning the injector needle valve; 6. Inspecting the battery circuit for short circuits; 7. Adding sufficient diesel to the tank; 8. Changing the diesel model used. Reasons for difficulty starting a diesel vehicle are: 1. Fuel supply system malfunction; 2. Insufficient combustion chamber gas pressure; 3. Empty fuel tank or failure to open the tank switch; 4. Blocked pipelines or filters; 5. Worn fuel injection pump; 6. Stuck injector needle valve.
My old diesel pickup truck got frozen once last winter, almost made me late for work. The most straightforward solution is to park it in a warm garage overnight. If that's not possible, pour hot water over the diesel filter and fuel lines—just be careful not to get any on the electrical components! Prevention is actually more important. Remember to switch to winter-grade diesel before winter arrives, choosing between -10 or -35 depending on the temperature. When refueling, add a bottle of diesel anti-gel additive, which is available at gas stations and can lower the freezing point by about 7-8 degrees. Once, when I was in a hurry, I used a hairdryer to blow hot air at the fuel tank for half an hour—a crude but effective trick. Now I've made it a habit to park in a sheltered spot whenever possible and always keep the fuel tank at least half full to prevent wax buildup in the fuel lines.
