should you let a automobile warm up the first time you start it up?

Answer 1

It is helpful, and a good idea to. I usually let mine warm up about a minute before I run off mad like. J/K. Its better for the winter months, helps to warm up the oil to work properly.

Answer 2

The reason you used to have to let them run for a few seconds before taking off was that oil filters used to didn't have a check valve in them, thus, when you cut the key off the oil could drain back into the crankcase leaving the parts of the engine with very little lubrication. Then when the vehicle started, it took a few seconds for the pump to pick the oil up and circulate it again through the engine. You see what running high rpm's would do over an extended period of time? Some cheaper filters today, actually many, don't have them. Especially toyotas have to have check valve type filters. If you don't use a factory filter I do know that AC Delco has them. I don't know about now but Fram didn't use to have them, or so I was told by the Toyota mechanic. As for the answer, no, you don't need to warm it unless you are in a place with an arctic climate where the oil gets so cold it is like molasses. Then you might want to consider warming it up.

Answer 3

Yes. It is a little important to let things warm up a little bit. It's less important in the summer time than it is in the winter time. Put a quart of oil in your freezer for a few hours and then try to pour it out and you will see why. It takes a moment to build up oil pressure in the engine and cold oil doesn't flow very well. Engines are designed to operate around 200 degrees. The potential for damage is greater if you push a cold engine too hard, but normal driving should not pose any excessive problems.

Answer 4

I don't think it's so much of an issue in the summer unless the car has been sitting for many days without having been driven.

In the wintertime I like to let the car run for about 5 to 10 minutes to warm up the engine/oil before taking it out on the road....

Answer 5

Yes. You should let the vehicle warm up for about a minute when starting from a 'cold' start. Cold start meaning that the engine temprature guage is on C, not the temprature outside. It lets the engine pull the oil back up from the oil pan and get circulating. Kind of like when you oversleep and get up and run out the door before you're awake, not good.

Answer 6

I wouldn't bother with that. If it is new then it has already been run at the factory as a part of their quality check. If on the other hand you just built this engine from a bare block it will get plenty of warm up time while you are setting the timing and adjusting the carb (that is if you use an engine that predates 1988

Answer 7

No most modern cars have no choke warm up is not necessary and wastes gasoline. Fuel injection and electronic engine control keeps the fuel mixture just right. Just drive easy the first few minutes after the temp gauge starts moving up then the motor is ready for full power if you want.

Answer 8

Don't much need to in warm weather,in cold weather you might have to let the engine run for a few minutes to get the fluids warmed up.

Answer 9

Just get the oil circulating and then you can go on your way. No need to set there and warm it up. The operating system is designed to adjust fuel, timing to keep the engine operating efficiently no matter what conditions you are operating in.

Answer 10

Have you've ever had to replace a cracked exhaust manifold on a minivan. I have.

My wife now ALWAYS lets the van warm up about a minute or so.
