“Rise and shine, campers, and don’t forget your booties because it’s chilly out there today…. Every day is chilly out there. What the hell is going on at Miami Beach?” (From “Groundhog Day”)
That’s true, here in the Rocky Mountains of Colorado, winter has returned. With a so-called “polar vortex” expected tomorrow, we thought it would be appropriate to display a video of some of the best “cold diesel starts” from last month, as well as provide some recommendations on how to start a diesel engine on a chilly day. Take a look at some of the suggestions provided below.
A Few Tips On Starting a Diesel Engine On a Cold Morning:
1. Glow Plugs and Block Warmers: On a chilly day, the vast majority of diesel engines can be started with glow plugs or block heaters. Glow plugs work by heating the internal combustion chamber, allowing for proper compression and, eventually, ignition.
2. Wait for the Glow Plugs to Warm Up: If the combustion chamber isn’t sufficiently heated with glow plugs, cold fuel sprayed over the semi-heated plugs will cause the diesel fuel to gel and stick to the cylinder heads. The wall of the heads or the surface may be damaged as a result of this.
3. Install a Second Battery: Make sure you have a fully charged battery or a separate battery specifically for the glow plugs installed. Glow plugs require a significant amount of power from your vehicle’s battery to operate. The capacity of a battery to keep a charge decreases as the temperature drops. At 75-80 degrees Fahrenheit, a battery will have 100 percent power available, but at 0 degrees Fahrenheit, it will only have 46 percent. Installing a second battery could mean the difference between the motor starting and not starting.
4. Change the Oil Frequently: At 0 degrees F, an engine is typically 2-3 times harder to start due to heavier oil lubricating the engine’s hard internal parts. The greater resistance on the bearings and moving parts, the thicker the oil. Most people are unaware that the crankshaft does not “sit” on the bearings; rather, oil pressure raises the crankshaft, which floats on top of the bearings in an oil cavern. Having enough new oil with a high chemical grade will assist in keeping the internal diesel engine parts lubricated and aligned.
For diesel engines, both synthetic and natural mineral oils are suitable. Oil “goes bad” mostly as a result of chemical bi-products from the combustion cycle, such as silicon oxide and different acids, being captured in the suspension. It also loses viscosity by transferring a lot of heat away from the combustion cycle and limiting oxidation exposure at higher temperatures. Diesel engine oil is destabilized by heat, pressure, and chemical reactions.
When oil fully oxidizes, the additives separate and begin to chemically break down, resulting in black engine sludge. If a diesel engine is not unclogged and cleaned, sludge will eventually ruin it. As a result, it is critical to change the oil on a frequent basis, especially in colder locations.
5. Turn Off All Non-Essential Accessories: On a chilly winter day, you only have so much battery life available. When starting the engine, turn off headlights, radios, iPods, phone chargers, heaters, and air conditioners. If at all possible, avoid using these gadgets while the engine is running. These devices divert vital amps away from glow plugs.
6. Use the Correct Diesel Fuel: There are two types of diesel fuel: Diesel #1D and Diesel #2D. The most extensively utilized diesel fuel on the market is Diesel #2. If you go to any gas station, you’ll almost certainly find Diesel #2D as the major fuel option. Diesel #2 is the standard fuel recommendation for regular driving conditions, according to all of the major auto manufacturers. Diesel #2 has a lower flammability than Diesel #1. A higher cetane number indicates that the fuel mixture is more volatile. For light-duty diesel engines, most manufacturers recommend a cetane rating of 40-45. Due to the higher fuel economy, heavy haul truck drivers prefer to utilize Diesel #2 over long trips. More combustion stability = greater, more consistent fuel mileage.
In cold weather climates, however, Diesel #1D is advised. The viscosity of diesel fuel is also measured. Because #1D diesel is thinner, it flows more freely within the engine. During cold temperatures, Diesel #1D is also less likely to thicken or turn sludge-like. In cold conditions, the higher chemical volatility, which is generally a hindrance, becomes an asset since it ignites much quicker during compression. During the winter months, many stations will provide a blended Diesel #1 and Diesel #2 choice, despite the fact that Diesel #2D is the most popular diesel fuel option.
7. Use Winter Fuel Additives: Winter blend diesel fuel additives may be purchased at most gas and service shops and added to your diesel fuel. The Cold Filter Plugging Point (CFPP) is a standard test that determines the rate at which diesel fuel will flow through a filtering device under cooler circumstances. A Low Temperature Flow Test (LTFT) is also available, which evaluates the operation of diesel engines with no or inappropriate additives in the fuel lines. It’s worth noting that the Pour Point is the third and final test for determining how effective diesel fuel is at working in freezing temperatures. The Pour Point refers to the temperature at which diesel fuel loses its liquid form and pumps cease to function.
When a diesel engine is started in a cold temperature environment, it may operate for a period of time below its Cold Filter Plugging Point (CFPP). When this temperature is reached, the fuel from the injector pump and injectors stops flowing, and the spill is returned to the fuel tank. Cold Filter Plugging Point Additives keep fuel from freezing in lines and gelling in the engine and gas tank. Fuel will be released to the injectors after the temperature has warmed up again.
8. Mix Additives During Fueling: These additives will only work if you add them above the Cold Filter Plugging Point (CFFP). At warmer temperatures, the additives need time to mix with the fuel. On a cold day, the additives should be added right after filling up with Diesel #1D at a service station. The heated diesel fuel straight from the pump should be warm enough to adequately combine the two solutions. Choose an additive that is rated at least 10 degrees cooler than the temperature you expect to encounter if you want to drive long distances in the winter.
9. Do Not Combine Additives With Winterized Diesel Fuel: Diesel additives are not a panacea for cold-weather problems. The additives will only prevent the formation of big gel particles in the engine, which could clog the fuel filter. Regardless of the temperature or additives employed, some gelling will occur. You should not add any additional additives to a gas station’s winterized diesel fuel (not to be confused with mixed diesel fuels). Incompatibilities with a variety of additives may cause the fluids in the fuel blend to degrade, obliterating any benefits.
If you suspect the fuel has gelled, replace the fuel filter. Wait for the temperature to raise or use a block heater to warm up the engine if you fear your diesel fuel has gelled before attempting to start it. On older vehicles, a gel in the fuel filter might obstruct the passage of fuel from the tank to the injector pump, requiring quick replacement. Because they are managed by the ECM, common rail injectors are less prone to gelling.
11. Keep Your Diesel Equipment or Vehicle in a Heated Location: It may seem obvious, but even a few degrees warmer might be the difference between a vehicle that starts and one that doesn’t.
On cold days, if at all feasible, keep trucks and tractors in garages, barns, or sheds. Consider utilizing a block heater on a timer a few hours before use to save time. It may not be a quick fix, but it will assist in getting the engine started.
12. Allow Engine to Warm Up Before Putting It Under Load: Allow the engine to warm up for 5-10 minutes before putting it under load. The harder internal parts of the engine are put under higher stress when the engine gets colder (camshaft, crankshaft, connecting rods etc…) The oil temperature will reach appropriate levels and effectively lubricate the engine after only a few minutes of warming.
How do you start a frozen diesel?
Gelled gasoline and electrical failure are the two most common reasons why people have problems with cold diesel engines. Cold diesel engine-powered apparatus must therefore be adequately maintained before being exposed to freezing temperatures. With that in mind, here are six recommendations for starting a diesel in cold weather and keeping your equipment in good working order over time.
Do Not Underestimate Warm-Up Time
It’s critical to allow your cold diesel engine to warm up. Allow your equipment to warm up for at least five minutes before using it; this will allow the hydraulic oil to warm up. If you don’t, the engine will have to work more than it needs to.
Consider Heating Options
When it comes to heating your gear and keeping it working properly, you have various alternatives.
- An electric block heater heats the coolant in the system, which warms the engine block and oil in the crankcase. This makes it easier for the engine to flip over.
- A diesel-fueled coolant heater can be used to warm up your engine in areas where power is not commonly available.
- Glow Plugs: These can aid in the ignition of cold gasoline and also heat the fuel-air combination inside a large engine.
- A Battery Tender: As the temperature drops, the cranking amperage of equipment batteries decreases. While machinery is susceptible to this type of failure, a battery tender will continue to function as long as it is fully charged. Battery cables should be checked before winter for owners of cold-diesel equipment. A battery’s ability to start machinery is harmed by bad connections.
Keep Your Diesel Exhaust Fluid Thawed
If you plan to add DEF to your apparatus later, keep it above 12 degrees Fahrenheit to prevent it from freezing. Although freezing does not reduce the uptime of your equipment, keeping DEF on hand ensures that it is ready to use when needed.
Address Frozen Fuel
During the winter, diesel fuel creating wax crystals is a more usual impediment to machinery starting smoothly. Fuel filters will become clogged as a result of the contaminated fuel, and the engine will not start. Using winter-blended diesel fuel, which lowers the temperature at which these crystals form, is one technique to prevent crystals from forming in the gasoline.
According to the University of Tennessee Agricultural Extension Service, if your fuel has frozen or gelled together, you should change the fuel filter and reheat the fuel before starting the engine. This prevents the frozen fuel from obstructing the flow of fuel from the tank to the injector pump.
Keep Your Engine in a Warm Area
If at all possible, keep your diesel engine in a warm place away from the elements like sleet and snow. Keeping the engine in a warmer environment, even if it’s only a few degrees warmer, can help it warm up faster.
Make Sure Your Fuel Tank is Full
Condensation in a fuel tank can eventually freeze, causing difficulties similar to gelled fuel. In the winter, keep your fuel tank as full as possible to prevent condensation from forming. A winter diesel fuel additive may also help to prevent your gasoline from freezing up.

How do you fix frozen diesel?
If the cold weather catches you off guard, your diesel-powered rig or light vehicle may be difficult to start or not start at all.
This happens because diesel fuel thickens inside filters and fuel lines, clogging your truck’s fuel system by forming a gel. For a truck owner/operator or anyone trying to travel and gets trapped on a dark and lonely highway in the middle of nowhere, this may be a very costly cost. Depending on the severity and location, emergency call outs to defrost a gelled system can cost anywhere from a few hundred dollars to a few thousand dollars.

How do you start a diesel car in cold weather?
The combustion chamber should be warmed up. Only diesel automobiles are eligible for this strategy. Turn the ignition on and wait for the glow plugs warning light to go out before turning it off. Rep these steps numerous times to get a good result. The functioning of glow plugs will quickly heat the combustion chamber to the desired temperature.
How cold does it have to be for a diesel not to start?
When it comes to diesel trucks, how cold is too cold? At 15 degrees Fahrenheit (-9.5 degrees Celsius), the diesel fuel in your fuel tank will gel and you will have problems starting your engine. Your diesel vehicle will have troubles if the temperature drops below 15 degrees Fahrenheit / -9.5 degrees Celsius. The diesel won’t be frozen solid, but it won’t be liquid either. You must now rely on heating solutions such as block heaters and glow plugs, which are not available on all diesel engines.
There’s a lot of debate regarding what temperature is too cold for a diesel truck. On the internet, it is stated that the freezing point of diesel fuel is roughly -112 degrees Fahrenheit or -80 degrees Celsius. Now you believe you will never be in a region that gets that cold, so you should be fine. Wrong.
It is not necessary for the diesel in your fuel tank and fuel lines to be solidly frozen to cause you problems. When the temperature drops below 15 degrees Fahrenheit / 9.5 degrees Celsius, the diesel fuel begins to change shape and becomes more like a gel. Consider a gel-like fuel that travels from the fuel tank to the engine. Traveling through the fuel lines would be difficult, and you would have difficulty starting your engine in the frigid winter.
How do you start a diesel engine after running out of fuel?
- Turn the ignition to the Run position for 30 seconds to prime the gasoline system, but do not start the engine. This permits the system to be primed by the pump.
- Crank the engine for 15 seconds after turning it off. If it still won’t start, repeat the first and second tasks until it does (cycle the key). Take a break if the engine doesn’t start after numerous attempts at priming, then repeat the process until it does.
- If the engine starts but stalls after a minute, wait another minute before trying again. Allow the powerplant to idle for a few minutes after it starts, then check for leaks before driving.
- If the truck’s engine refuses to start, have it towed to a shop or a dealership’s service department for professional diagnosis and repair.
How long does it take diesel to thaw?
In freezing weather, an emergency treatment replenishes frozen or gelled fuel, getting your vehicle back on the road and saving you time, money, and hassle!
In cold temperatures, use to liquefy frozen or gelled diesel gasoline caused by wax production or ice crystals. Quick-Thaw will completely thaw the whole fuel system in roughly 20 minutes if applied according to the guidelines. Excellent for diesel cars operating in colder locations, where wax crystals found in low- and ultra-low sulfur diesel fuels can cause filter blockage.
A bottle of Quick-Thaw should be kept on hand in every diesel truck for emergency cold weather rescue treatment.
What temp does diesel Ungel?
Cold weather is tough for diesel engines, but as temperatures drop into the teens below zero, diesel owners must contend with fuel gelling issues. Untreated diesel gasoline begins to gel at 32 degrees Fahrenheit and is entirely gelled at 15 degrees Fahrenheit.
How do you warm up a diesel engine?
You aren’t allowing your engine to warm up.
Don’t be the guy who starts his hot engine and cranks it up right away. The only thing you’re bragging about is your ignorance of the fact that cold, thick oil will not adequately lube your turbo and engine bearings. Allow your engine to warm up in the same way as you would in the morning. Allow the intake heater and glow plugs to do their jobs. Start the engine and give it some time to warm up evenly from the combustion heat.
