In winter, when the air temperature is minus 20 and below, the diesel engine is greatly supercooled. Because of this, the fuel freezes under the hood and in the fuel filter. To prevent this situation, it is necessary to insulate the engine.
Necessary
- - corrugated foamed polyethylene;
- - scissors;
- - a gun with silicone glue;
- - stationery stapler.
Instructions
Step 1
To get started, use the simplest and most affordable methods - insert a cold air damper into the radiator or cover the engine with a rag or warm blanket. But in severe frosts, such methods will be ineffective.
Step 2
For better engine insulation, place your vehicle on a pit or perform the entire process on a lift.
Step 3
First insulate the pipeline. This will prevent the fuel from cooling below critical temperatures. Take insulation. Corrugated polyethylene foam with a thickness of 5 mm is best suited. Measure the tube diameter and cut the required strip with scissors. Wrap the insulation around the pipeline and simply fix it with a stapler. Turn the resulting "tail" of the tube and lead it over the brake lines. Secure everything with sealant.
Step 4
Now, with the same material, eliminate the cracks in the engine compartment and cover the radiator.
Step 5
Remove the upper part on the radiator. To do this, unscrew the four screws and two latches. Measure the size of the opening. Cut a piece from the corrugated insulation to a suitable size. Fold it in half and push it to the left of the lock drive. After that, straighten it by slipping the top under the lock. There is no need to make any more fasteners - minor gaps will even be useful, so as not to completely block the cooling. The frontal flow will no longer be able to cool the engine, especially when driving at high speed. Do not worry about overheating, as diesel engines are not prone to it, moreover, you have left separate cracks in the engine compartment.
Step 6
In case of frosts from minus 15, additionally, insulate the fuel filter and rail. To do this, use the same piece of polyethylene, only with the foil down. It will reflect heat from the exhaust and boost manifolds.
Step 7
Such methods of insulation will make it possible to maintain the operating temperature of the engine and prevent freezing of the fuel lines.
