A harsh Canadian winter is the perfect time to put your diesel truck through its paces. However, its performance largely depends on how well you prepare it for the cold ahead.
In our previous article, we covered the basics of winterizing your diesel truck. But there are some crucial steps that many owners tend to overlook. Even if you've just bought a brand new vehicle, these tips are essential to ensure your truck runs smoothly all season long.
Glow plugs can take anywhere from 1 to 15 seconds or more to warm up, depending on outside temperature, engine condition, and their age.
**1. Test Glow Plugs**
If your truck has glow plugs, make sure they're working properly before temperatures drop below freezing. Faulty glow plugs can cause diesel to leak into the exhaust, make starting the engine difficult, and reduce overall power. While the truck may still run with one bad plug, this issue can strain the engine and lead to unexpected breakdowns.
Winter windshield washer fluid is vital for visibility in poor weather conditions.
**2. Use Winter Windshield Washer Fluid**
If you've been using regular windshield washer fluid during the summer, it will freeze when the temperature drops. Before winter hits, drain the old fluid and replace it with a winter blend—preferably rated for -40°C or even -50°C.
**Important:** Don’t just top off the summer fluid with winter fluid. The system pumps from the bottom of the tank, so if the old fluid freezes there, the new fluid won't help.
Regular oil changes by certified technicians can prevent major issues.
**3. Clean or Replace the Fuel Filter**
A clogged fuel filter can cause rough idling, hesitation during acceleration, or even prevent the engine from starting. Make sure your fuel filter is clean and functioning properly. If it's been a while since the last replacement, consider swapping it out. Most diesel trucks require a fuel filter change every 80,000 to 100,000 kilometers.
A block heater can significantly improve cold-weather performance.
**4. Test the Block Heater**
Many diesel truck owners don't even know about the block heater. Check if your vehicle has one and test it before winter arrives. Use a multimeter set to ohms. A reading between 9 and 25 ohms means it's in good condition. If it's lower than 9, it may need repair or replacement.
Even small cracks can become big problems in the cold.
**5. Fix Windshield Damage**
A tiny crack in your windshield can quickly spread in the extreme cold. Sudden temperature changes can turn small chips into large cracks. Inspect your windshield regularly and repair any damage before winter sets in.
By following these five steps, you can help ensure your diesel truck stays reliable and safe throughout the coldest months. For more tips on preparing your vehicle for winter, contact us today.
