The Proper Steps to Winterizing Your Semi-Truck

The Proper Steps to Winterizing Your Semi-Truck

November 26, 2022

The beautiful colors of the Fall will soon change to bare trees, followed by snow and ice, so prepare your semi-truck for snowy weather now! Winter weather can severely impact your truck’s overall performance. For instance, ice might build up on the air system, engine, rims, windshield, etc. This can make driving extremely dangerous and challenging. A well-winterized truck means you’ll be safer and more productive during freezing temperatures and on snowy roads. So, how do I winterize my truck? Don’t fret! Here are tips to help you out.   

Inspect the Fuel Filter and Water Separator

Reduce the engine damage risk by checking the fuel filter for any malfunctions. And also monitor the water separator daily. Water can contaminate diesel fuel and shorten its lifespan. Unfortunately, most operators aren’t self-cleaning. However, you can locate one near the fuel filter and turn the drain valve to empty the collected water. 

This is important during winter due to condensation inside a warm fuel tank as the outside temperatures cool. 

Inspect the Tires  

Be sure your tires are in good condition to navigate the icy and snowy roads ahead. Inflate the tires to the appropriate pressure rating. Plus, ensure you have the correct size and number of chains in your semi-truck. Finally, inspect the chains for twisted, worn, or damaged links and replace them if necessary.

Inspect the Battery  

Batteries strain a lot during freezing temperatures. You might wonder, ‘how do I keep my semi-truck batteries warm in the winter?’ Use a warmer under the engine hood. You can also pack your truck underneath a covered area. This keeps ice and snow from landing and freezing on the truck’s battery.  

Be sure to replace your battery if it’s about to die; most truck batteries usually last for about three years. However, if your battery is good and has life left, tighten the connections to terminals and ensure it’s securely mounted. Moreover, confirm the jumper cables can hold and share charge. 

Inspect Windshield

If your wipers are cracking, damaged, or old, take time to replace them. If they’re fine, wipe the edges with rubbing adhesive, like petroleum jelly. 

This helps remove any grease, oil, or dirt that might cause streaks or squeaking. Plus, repair small cracks or rock chips on your windshield.   

Use Fuel Additives

Diesel fuel contains wax and paraffin, which might crystallize at freezing temperatures. This emulsifies the water in the fuel and results in a gel and slushy-like fuel. 

This fuel doesn’t pass through the filters, which worsens when temperatures drop. The gel-like fuel can also lead to rough vehicle operations and sometimes engine failure. Avoid this by checking the Cetane Ratings of the fuel at the pump. You can also add anti-gel fuel additives to help enhance performance. Remember to check your owner’s manual for additive guidelines and follow mixing procedures correctly, or you might damage your fuel system.
