Make Sure Your Diesel Fuel and More are Ready for Winter
Weather forecasters are predicting not only one of the coldest, but the snowiest winters in the last five years. Here are a few simple tips to help maintain your equipment and fuel tanks.
1. Be sure you have adequately treated the bulk fuel tanks for the temperatures you will be dealing with. Think in terms of where the coldest point the truck will run to and treat accordingly.
2. Block heaters are not designed to warm an engine. They are designed to maintain the heat already generated in the engine. Thus it is crucial that the truck be plugged in while the engine is still warm.
3. Remind the drivers to UNPLUG the truck before starting it. Two to three seconds of the engine running while the block heaters are plugged in is enough to burn out the block heaters.
4. Do not idle the trucks. You will do more to COOL the engine by idling a truck coming off the road vs. shutting it off. (Engine temperature rises approx. 18 degrees when it is shut off.) Conversely, starting a cold truck and letting it idle is futile. If you need to warm a truck thats been sitting, get in it and drive it around the yard and exercise the truck once it has reached maximum oil-pressure. This will warm the engine, transmission, differential and suspension. Not to mention prevent running the risk of potential fines for idling for both the driver and the organization.
5. Remember to drain air-tanks and fuel water separators. As the ambient air temperatures fall, the ability for water to condense in fuel tanks increases and can be carried into the filter/heater unit. During periods of extreme cold this should be done on a daily basis. The fuel filters are the only protection the engine has against contaminants in the fuel. A larger micron fuel filter should never be used to extend filter life or increase flow. It may void the warranty and can be damaging to the pump and/or the injectors.
6/ Be sure air hoses are hooked up to each other or to the dummy gladhands when the equipment is not in use. This is one of the leading causes of brakes freezing up.
7. If moisture is present in an air line, use one cap full of brake line anti-freeze in the EMERGENCY (red) side ONLY. Never put it in the blue side or you may cause the brakes to lock up. Use only company supplied brake line anti-freeze, as there are many products out there that will cause damage to the internal brake system.
8. Be sure gladhands hook up tight. If they go on loose they will come off in a tight turn and will cause unnecessary cycling of the air compressor. Make sure you have a nice and snug fit.
These few tips can make the difference between go or no go situation, making that delivery commitment, or completing a run vs. a breakdown. Breakdowns during inclement weather are extremely dangerous. There are many great tips for proper fleet fuel system management in cold weather but best tip is to increase driver awareness and subsequently hold them accountable for action or inaction.
When fueling on the road, check at truckstops to make sure pump filters have been changed. Look for hydrosorb filters; these will remove water from the fuel before it gets in your tanks and forms ice or gelling.
Ask the supplier if they are using a bio-blended fuel and if it has been treated. Also ask if the diesel fuel has been tested for CFPP. Bio-blended fuels are harder to treat in the winter and will not perform like a ULSD.
