(WEAU) – Extremely cold temperatures can take a toll on your vehicle, especially if it’s been sitting outside. Experts recommend you let it warm up before driving it. They say this helps get the fluids properly flowing. Auto professionals also say it’s a good idea to invest in a frost plug heater.
Can the cold make it hard to start a car?
Even a battery in good condition loses half its potential power at 0 F. At the same time, motor oil and other fluids thicken, requiring more battery power to start your vehicle than on a warm day. That’s why a dead battery is one of the most common reasons a car won’t start in the cold.
Make sure the radio, headlights, heater, etc., are switched to “off,” so they aren’t pulling energy from your battery and engine. Now put the key in the ignition and turn it from the “off” to the “start” position about ten times. You’re “cycling the key,” which can help warm up the battery and starter.

How do you warm up a cold car battery?
“You pour hot water over the battery, and what you’re doing is warming up the battery,” Kirchdorfer said. He said to use boiling hot water, because the hotter the better.
What causes a car to have a hard time starting?
If your vehicle won’t start, it’s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you’re dealing with a battery or an alternator problem. Here’s how to know which one is the culprit.
Why does my car sometimes struggle to start?
Starter relay and starter motor issues
The electrical contacts that provide power to the starter motor will wear down over time, transferring less and less power to your starter motor. With less power, the starter motor will spin slower, causing that struggle you feel when starting your car.
Why does my car struggle to start but runs fine?
If the car struggles to start but runs fine, you should consider the coolant sensor for any faults. If the coolant sensor is faulty, then the fuel and air mixture will not work properly. When that happens, the engine will fail to start at the first few tries because the chemical reaction takes time to complete.
When you have a faulty ignition switch, it may not activate the battery to produce the electrical current needed to start your car. So, during cold days your battery power might be too low, and the starter switch is slow, leading to car start problems.
How do I unfreeze my ignition?
Why does my car not start after sitting overnight?
A difficult start could be due to a number of things, from a dying battery to a faulty starter. But if your vehicle has a hard time starting after sitting for just a few hours, it can cause an extra layer of confusion. When this happens, one of the most common causes is low fuel pressure.
What do u do when your car freezes?
3 Things to Do When Your Car Engine Freezes
Running Your Car Can Make the Engine Freeze Worse. It is imperative to not turn the car on.
Let the Frozen Engine Thaw. Once you have left the car in a warm place, let the engine thaw out.
Put in the Antifreeze.
How do you start a frozen engine?
Try to start your car:
Turn the key and hold it.Let the engine crank for about 10 seconds, but don’t hold it any longer – you don’t want to overheat or flood the engine. If the engine doesn’t crank, let the engine rest for a few minutes and try again.
How do you know your engine is frozen?
The primary sign of a seized engine is a vehicle that doesn’t crank or start. In some cases, the engine might turn over slightly (often while making abnormal noises), but it will refuse to crank normally or run. You might also hear a click or clunk noise as the starter tries to engage the engine.
That’s what we asked the experts, and here’s their answer. Yes, engine coolants can freeze. The freezing point would depend on the antifreeze to water ratio. 50/50 engine coolants have a freezing point of -35 degrees Fahrenheit while a 70/30 coolant would freeze at -84 degrees Fahrenheit.
How do I keep my fuel lines from freezing up?
A better tactic is putting fuel additive containing antifreeze into the fuel system. This additive will prevent the fuel lines from freezing, even if the surrounding air is well below freezing. You can use antifreeze to solve a frozen fuel line, too. It doesn’t matter if the gas tank is partially full or almost full.
How long does it take an engine block to freeze?
If you have a heater it will freeze before the block does. I think my service department said it will take about a night of a freeze for the heater to crack and about 24 hours for the block.
How cold does it have to be before antifreeze freezes?
The name “antifreeze” might trick you into thinking the coolant cannot freeze at all. But in actuality, pure antifreeze, which is ethylene glycol, will freeze between zero and minus five degrees Fahrenheit.
Is it OK to put straight antifreeze in your car?
Running on pure antifreeze-coolant is pure folly and only will hasten your engine’s demise. Reason No. 3 is that water must be mixed with the antifreeze-coolant in order to keep the performance additives (silicates, phosphates and nitrates) suspended. Without water, these important additives tend to settle.
Can you just put antifreeze in the car?
There is no problem with just topping up the coolant. You can add the coolant without flushing out the old. However, with time, the older coolant becomes acidic. This can cause corrosion, and afterward, can cause defects in the cooling system.
