When To Plug In A Diesel?

Many of us in the Edmonton area rely on driving to get to work, bring our kids to school, and get food for our families during the winter months. While driving in light winter weather isn’t too bad, harsh winter weather puts a strain on engines. Our engines, like the majority of us, dislike the extreme cold. They work best in warmer weather, and while we can’t control the winter temperatures, we can use engine block heaters to keep our engines warm. Many of our Ford automobiles come equipped with engine block heaters to keep your engine warm throughout the chilly winter months. The cord to plug in your engine block heater is normally situated under the hood, as seen in the photographs below, and we’ve even drawn a box around it for your convenience.

What is an Engine Block Heater?

Let’s take a look at what an engine block heater is and what it does before we get into when you should plug it in. When you start your car, oil circulates through the engine block, lubricating all of the working parts. When we have harsh winter temperatures, such as -20° C or below, the oil thickens and becomes sticky. This makes it more difficult for the oil to travel through your engine, causing it to work more, consume more petrol, and emit more pollution. The engine block heater maintains a temperature that allows the oil to remain thin and flow freely through the engine block.

When to Plug in an Engine Block Heater

While the precise temperature at which you should consider plugging in your engine block heater varies, the main thing to know is that if it’s going to be severely cold overnight or early in the morning, you should probably plug in your vehicle. Newer vehicles can usually start at temperatures as low as -30° C, but if the block heater isn’t connected, the engine will be put under more strain. To be safe, plug in your engine block heater when the temperature drops to -15° C or lower. If you drive a diesel car, you may need to use the engine block heater to keep the temperature from falling too low.

How cold should it be to plug in diesel truck?

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.

Do you have to plug in diesel trucks in the winter?

Cold has the same vengeance on mechanical objects as it has on organic ones. When winter arrives, efforts must be taken to safeguard diesel engines, new oil burners, and especially older oil burners with glow plugs, in order to maintain powerplants and ensure rigs remain reliable until climates warm up.

Why should I plug in my diesel truck?

As the winter months approach, you may notice diesel pickup trucks and semi-trucks hooked into power outlets. Yep. There’s a term for that. That’s why I’m here to tell you why.

A diesel engine, unlike a gasoline engine, does not use a spark plug to ignite the fuel that is injected into the cylinder; instead, it relies on the heat and pressure created by the piston moving up and down inside the cylinder. To ignite the diesel fuel, that cylinder must be at a specified temperature.

As we all know, the colder it gets outdoors, the colder everything gets outside, including your diesel engine’s cylinder. The longer it takes for the cylinder to warm up, the longer it takes to start your truck. This is where your diesel engine should be plugged in.

The line you see is attached to a block heater located inside the truck. This block heater raises the temperature of the engine coolant to roughly 85 degrees Fahrenheit. In cold weather, this keeps the cylinders warm, enabling for faster and simpler starts. Not to mention the comfort of a heated heater when you first start your truck.

Can I leave my diesel plugged in all night?

Is it okay for me to leave my truck plugged in all night? After three hours, the temperature reaches its highest point ever. Any additional expense is simply a waste of money. If you leave it plugged in all year (winter, summer, or in between), the engine will not be destroyed, but you will have to pay $100 every month to keep it hooked in.

Is it bad to start a diesel in the cold?

In cold weather, diesel engines are more difficult to start because they rely on high temperatures caused by compression to ignite the injected fuel. In fact, starting a diesel engine at 0°F (-17°C) is five times more difficult than starting one at 80°F (26°C).

How long should I let my diesel truck warm up in winter?

If the temperature is below zero degrees Fahrenheit, you should allow your engine to warm up for up to seven minutes. Warm-up time should be three to five minutes if the temperature is between zero and fifty degrees. Warming up to above fifty degrees takes only one or two minutes.

How do you keep diesel fuel from freezing?

Using an anti-gel fuel supplement is one approach to keep diesel fuel from crystallizing (or gelling). Anti-gels for diesel fuel are simply added to the gasoline (just drop it in the fuel tank). Diesel fuel’s freezing point is lowered by anti-gels, making it less prone to freeze in cold temperatures. (**IMPORTANT: diesel fuel conditioner, diesel fuel supplement/additive, and anti-gel are not the same thing. A diesel fuel conditioner or a supplement such as CleanBoost Maxx WILL NOT keep diesel fuel from freezing).

What temp should a diesel be?

Overheating an engine can result in head gasket failure and damaged cylinder heads. An engine’s operating temperature should be between 190 and 220 degrees Fahrenheit. The cylinder head, cylinder liners, and engine block will be stressed if the temperature rises above 190–220 degrees. Overheating stresses certain parts, causing them to grow beyond the engine’s tolerances. A blown head gasket and/or a warped or cracked cylinder head will result as a result of this.
