【 Maintenance 】 Key Points For Winter Maintenance Of Special Purpose Vehicles (Part 2)

In Winter, The Temperature Drops Sharply, And People Need To Add Warm Clothing And Change Their Diet To Maintain Their Lives. Vehicles Also Need To Change Their "diet"; Come And Continue Working. Different Seasons Require Adjustment Of Specialized Vehicle Maintenance Projects Based On Different Temperatures. In Order To Enable Car Owners To Better Protect Their Vehicles, Improve The Performance Of Specialized Vehicles, And Also Extend The Service Life Of Vehicles. Let's Learn About Winter Sanitation Vehicle Maintenance Tips Together Now!

Lubricating Oil

The Lubrication Requirements For Special Vehicles Are Higher In Winter. If Summer Engine Oil Is Used, It Must Be Replaced. Engine Oil That Has Been Used For A Long Time, Turns Black In Color, And Has Poor Adhesion Should Be Replaced To Ensure Smooth Engine Start-up. First, Let Me Introduce The Meaning Of The Engine Oil Label: "W" Stands For Winter, And The Smaller The Number Before It, The Better The Low-temperature Fluidity Of The Engine Oil. The Number After "y" (- Horizontally) Is An Indicator Of The Engine Oil's High Temperature Resistance, And The Larger The Value, The Better The Engine Oil's Protective Performance At High Temperatures. The Following Are The Labeled Parameters: 5W Can Withstand External Low Temperatures Of -30 ℃, 10W Can Withstand External Low Temperatures Of -25 ℃, 15W Can Withstand External Low Temperatures Of -20 ℃, 20W Can Withstand External Low Temperatures Of -15 ℃, 30 Can Withstand External High Temperatures Of 30 ℃, 40 Can Withstand External High Temperatures Of 40 ℃, And 50 Can Withstand External High Temperatures Of 50 ℃. For Example, The Applicable External Temperature Range For 5W-40 Engine Oil Is From -30 ℃ To 40 ℃; The Applicable External Temperature Range For 10w-30 Engine Oil Is -25 ℃ To 30 ℃. Obviously, The Heat And Cold Resistance Of 5W-40 Is Better Than That Of 10W-30, But The Price Is Relatively Higher.

Antifreeze

The Amount Of Antifreeze Must Be Appropriate. Different Regions And Vehicle Models Should Determine The Freezing Point And Type Of Antifreeze. Antifreeze That Has Been Used For More Than Two Years Should Be Replaced, And Mixed Antifreeze Must Be Replaced After One Year. Be Careful Not To Mix Products Of Different Brands And Models. For Places Like Minus 30-40 Degrees, The Level Of Antifreeze Required Is Very High, And It Is Necessary To Replace It With A Higher Level Of Antifreeze. Another Important Point Is That After Various Vehicles Stop Working, They Must Empty The Remaining Water Inside The Vehicle, Especially The Water In The Pipes And Pumps. Freezing And Damaging The Vehicle Will Not Be Worth The Loss. Vehicles Equipped With Water Circulation Pumps Should Replace Their Cooling Water With Antifreeze During Winter, And By The Way, Fuel. In Cold Regions, It Is Common Knowledge To Add Fuel With A Lower Freezing Point During Winter.

Braking

Pay Attention To Whether The Brake Fluid Is Sufficient And Whether The Quality Has Deteriorated. If Necessary, It Should Be Refilled Or Replaced In A Timely Manner. Pay Attention To Whether The Braking System Weakens, Deviates, The Pedal Force Of The Brake Pedal At High Speeds, And The Position Of The Wheel Lock Point During Braking. If Necessary, Clean The Entire Brake System Pipeline. Most Large Vehicles Have Air Brakes, And Maintenance Is Also Necessary For Air Brakes. Check If The Brake Wheel Hub Is Frozen Or Frozen, Which May Cause The Brake To Fail To Return To Its Original Position Or Stop The Car. Check If There Is Any Air Leakage In The Pipeline, If The Air Pump Is Working Properly, If The Belt Is Damaged, And If The Brake Pads Are Worn Out. Safety Comes First.

Wheel Alignment

In Winter, The Road Surface Is Prone To Ice And Snow, And Materials Such As Rubber, Metal, And Plastic Become Harder At Low Temperatures. The Handling System Also Becomes Heavier, Reducing The Driving Experience. Incorrect Four-wheel Alignment Can Easily Affect Safety.

Glass Cleaning

The Amount Of Glass Cleaning Solution Used In Winter Is Obviously Less Than That In Other Seasons, But It Can't Be Ignored. Some People Use Clean Water And Clear Water Instead In Other Seasons. However, Those Substitutes Often Freeze In Winter, So They Can't Be Used In Winter. Instead, We Must Replace The Glass Cleaning Solution That Is Not Afraid Of Freezing With Light, And We Can Also Add Alcohol Or Baijiu In Clean Water To Reduce The Freezing Point.

Air Conditioner

Air Conditioning Is Not Used In Winter, But It Is Necessary To Check Whether The Air Conditioning System Is Clean And Whether There Is Any Blockage Or Water Accumulation. At The Same Time, It Must Be Turned On For About 5 Minutes Every Week To Lubricate The Components And Prevent Hose Hardening.

Waxing

After Entering Winter, The Cold Weather And The Frequency Of Cleaning Vehicles Will Also Decrease, So Waxing At The Beginning Of Winter Is The Best Way To Maintain Car Paint. In Addition, Waxed Car Bodies Are Less Likely To Get Wet And Are Less Likely To Condense Into Ice During Winter.
