If you have a late-model car or SUV with a 4-cylinder engine, and it is parked outside in below-freezing temperatures, it may take up to 10-15 minutes of driving before you can get good heat from the vents. An older car with a larger engine may take 5-10 minutes of driving to warm up.There’s no real answer to how long it should take a heater to warm up during cold weather. It really depends on several different factors. One of those is the type of vehicle you’re driving. Most older cars can require several minutes or so to come up to operating temperature and for the heater to start working.
Why does my car heater take so long to warm up?
A few things that cause automotive heaters to work less well are low coolant levels in the radiator, a faulty heater valve, or the thermostat is stuck open. Have a certified mechanic replace your thermostat if necessary or diagnose and repair other cooling system issues, such as leaking coolant.
How can I make my car heater faster?
TURN THE TEMPERATURE TO COLD AND TURN OFF THE FAN Yes, that may seem backward but that's how a cars heating/cooling system works. Then, after driving for a bit, turn it to hot and turn on the fan. It'll get hotter faster this way, than if you were to get in and turn it to hot with fans on full.

Why is it bad to warm up your car?
By letting your car sit to warm up, it's actually putting extra fuel into the combustion chamber, which can get onto your cylinder walls. Because gasoline is an excellent solvent, too much on your cylinder walls can dissolve the oil that lubricates your cylinders, leading to shorter life on crucial components.
What happens if you don't warm up your car?
By letting your car warm up, instead of just driving it cold, allows the engine's components to disperse oil evenly throughout every moving part. Without the proper warmup time, you can risk damaging your engine's pistons, which may warp or experience undue wear as a result of being driven cold.
Is it necessary to warm up your car before driving?
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. This tool helps warm up the engine and prevent fluids from freezing.
Why isn't my car heating up fast?
A heater can stop working for a number of reasons, including: A low antifreeze/water level in the radiator due to a leak in the cooling system. A bad thermostat that isn't allowing the engine to properly warm up. A blower fan that isn't working properly.
Why does my heating take so long to heat up?
It may be your boiler simply doesn't have the grunt to heat your house for that long. Try setting your night-time temperature a bit higher and see if that improves the situation. It could also be that your system is gunked up, leading to poor water circulation in your system.
Why is my car heater not getting hot enough?
Common causes are thermostat problems, heater core issues, jammed heater flaps, air bubbles, and low coolant levels. Some of these reasons are partly due to the age of your vehicle, while others are a result of poor vehicle maintenance.
Why does it take so long for my heater to turn on?

Is it bad to rev cold car?
It helps distribute oil throughout the engine and get the engine block and engine oil up to temperature. Revving the engine won't speed up the process. In fact, that could cause easily avoided damage. Cold revving causes abrupt temperature changes that create stress between the engine's tight-fitting components.
What happens if you drive on a cold engine?
So the longer you let a cold engine idle, the more fuel you waste and the more you increase the chance of fuel residue build up. Fuel residue build up can lead to poor engine performance and a reduction in mileage.
How do you destroy a car engine?
A mixture of salt and water can clog the fuel filter, destroying the engine. In some cases, you may also try using a detergent in the gas tank. While this doesn't cause corrosion, it can corrode the engine and make it unusable.

Should I warm up my car in winter?
Why is my car faster when it's cold?

Should I start my car every day in cold weather?
Experts at AAA, a federation of motor clubs, say it's not a good idea to warm your car up to keep it from freezing. Drivers should start their engine and allow it to idle only for the time it takes you to fasten your seat belt. This time ensures lubricating oil gets to all of the engine's vital parts.

Low Coolant Level The coolant (usually a mixture of water and antifreeze) in your engine doesn't just work to keep the engine from overheating: It's also the source of heat supporting the heating system. If there isn't enough coolant in your system, the heater core will blow cold air into your car.
How long should a radiator take to heat up?
Once you've closed your radiator valves, it's safe to turn your central heating and hot water back on. If you've been successful, your radiators should start to heat up within a few minutes. You can also check the pressure gauge on your boiler and check that it reads between 1 and 2 bars.
