Does "reving" your engine, help the heat in your car get hotter faster when first starting it on a cold day?

Answer 1

Bad idea. When you start the engine on a cold day, the oil is cold and flows slowly, so revving the motor unnecessarily could score the bearings. Start the motor, let it idle for maybe 30 seconds to build up a good oil flow, and then drive the car gently for the first few minutes. It will warm up normally, and once you feel warm air coming out of the heater, you can drive normally.

Answer 2

It may or you would think so. However you are taking a greater risk of ruining your engine.

Reving a cold engine does not allow the oil to warm up and be thin enough to coat and lube the pistons properly. It is like you trying to run a long distance race with out training/conditioning of your body.

The best and fastest way to warm the engine is to drive it. Once you start it let it idle for 20-30 sec or until the high rev slows down.

Then drive it slow in first for a block or two. Shift to 2nd or D2 and drive slow for 2-3 blocks. All together drive slow for bout half to a mile.

The engine gets lubed properly/faster. You get more miles per gal cause you are traveling and getting closer to your destination. Your car will be happy and smile at you.

Oh, also if you can stand it, don't turn on your heater/fan till the thermostat moves to warm position.

Answer 3

Funny that you have so many answers and yet no right answer. Whoever replaced your starter lied to you because your starter is still bad. If you turn the key and hear a 'click' then the solenoid of the starter is good an the brushes and/or armeture are bad. If you turn the key and hear nothing then either the solenoid of the starter and/or the connectons are bad. Either way, the solution is a new starter. In a 68 Cadi, the igniton pretty much directly interfaces the starter so there's no wiring to disrupt the signal to start. If you turn the key and she doesn't light then it's either the ignition switch (which when broken, is broken) or the starter (which is widely known to intermittently go bad when hot) A new starter for a 68 cadi should run about $40 plus labor. Don't get screwed on the labor though; a starter job is about as easy as it gets on those older cars. A decent mechanic should be able to complete the job in 30 minutes or less. It's almost as simple as changing the oil. If you live near Lubbock, I'll do it for a 30 pack.

Answer 4

Yes reving the engine will. I t would be just as well to hop in and begin your travels. I do not recommend reving the engine at start up because the oil has been draining the whole time your car has been sitting. That means that at start ups the engine is not as lubricated as it is after it has begun to idle. You have a themostat on a water cooled engine that must reach a certain temp before it will allow the water to cycle into the cab of the vehicle. On an air cooled engine, it must be warm enough to warm the air going to the cab. If you must warm up the car before you get in, you can have a remote starter installed for a few bucks. Then you start your car and watch the windiws to know when you are ready to go!

Best rule of thumb is to keep the engine runnig slow as possible to warm the engine up,- cold oil flows slowly, and could actually "scorch" bearings on the crank, - if you rev the engine way up when it is starting in very cold weather! This will shorten your engines life!! Now a faster idle than normal after the oil pressure gets up is a different thing!!

If you are wanting heat for the heater, get a "tank heater" and plug in at night, - you will have heater and defroster right away, -your engine will start much easier. I'm talking sub-zero weather here, -also Diesels with bad glowplugs will start easily this way (till you can get them fixed)! When I lived in Wisconsin, and the temps were -30 or beter, my car started,-- while a lot of the neighbors didn't! Did you know that the battery has less power available in real cold weather (just when you need more to crank the "stiff engine"?

Answer 6

Raving your engine when first start in the cold day, that sound like you want a new engine for your car, i don't know if you understand why most people warm they car up for at least 5 to 10 minutes before they driving, the reason is when you first start your car in the cold morning all part in side need to be lubricated with oil, oil pump can pump the oil up to cylinder head so they can lubricate all the valves, spring ,etc...... if you raving you engine before oil can get to piston chamber crankshafts valves and all the part of your engine it will created more heat long period of time it eventually hurt your piston ring and your valves seal caused the oil to leak and caused the car to smoke.i don't think it will help the heat get hotter faster, if you want your car to heat faster change your thermostat to higher temp.

Answer 7

The best way to warm up your car is to turn on the A/C or defrost. The A/C compressor will run on either setting. This will put a 10hp load on your engine when you have it setting in the drive warming up. Also, many cars have the OD circuit going through the temp. control sending unit so that the car won't go into OD until it warms up. Good luck.

Answer 8

It is a waste of gas, and will wear the engine out faster. The engine warms up fastest under load, so start driving at a moderate pace and acceleration as soon as practical after starting.

Answer 9

I wouldnt do it. your just forcing cold think oil over all those moving parts just go out like 10 minuets earlyer or let the dog out while the car warms.

Answer 10

I think so
