Don’t Let April Showers Bring Diesel Fuel Issues

The spring temperatures bring a much-anticipated break from the frigid winter months, but we all know that when the spring arrives, so too does the rain, which has some drawbacks for diesel fuel vehicles. But by staying on top of your preventative maintenance, you can leave worry behind with the cold temps.

Diesel and Water Don’t Mix

Have you noticed that when the rainy conditions hit your area, your diesel fuel vehicle tends to have various fuel-related problems? This is caused by the following:

  • Damage to the Injectors
    An internal combustion engine relies on the atomization of fuel, which can’t happen effectively if water has entered the fuel injectors.
  • Microbes
    Algae, fungi and bacteria thrive on water, so when water gets into the fuel, these microbes can clog filters and corrode the fuel system.
  • Weakened Components
    Everything from the fuel tank to fuel lines can become corroded, leading to costly repairs, but most certainly poor engine performance.
  • Bad Fuel
    Water oxidizes fuel, which creates sediment and other contaminants that will degrade the fuel.  

Preventative Maintenance

Being proactive offers great advantages in mitigating risks associated with moisture buildup. One of the most thorough measures to take is to have your fuel tank and drainage system inspected for areas where moisture can get in.

Fuel additives are made specifically to prevent moisture from creating problems in your vehicles by dispersing it, preventing microbial growth and stabilizing the fuel. Just follow the directions on the additive you use or ask your mechanic for recommendations.

Ask your mechanic about replacing your fuel tank caps and seals with sturdier, more secure products for that extra layer of protection. While you’re at it, ask about water-absorbing filters and fuel additives that can help clear the water from your system. These will also keep the microbes and bacteria from taking over.

Other Systems to Check

It’s not all about the fuel-related issues; preventative maintenance for diesel fuel vehicles should also include monitoring and servicing items related to the electrical system and the brake pads, rotors and brake fluid.

Spring is also a great time to do your seasonal maintenance, which includes checking and/or changing your coolant, transmission fluid and engine oil. Take this time to see what the cold temperatures have done to your battery (cold weather has been known to weaken batteries), clean its terminals and make sure the connections are tight.

Finally, because spring is the season for pollen and various other debris, get your air filters replaced so your engine can receive proper airflow.
