why do you warm up ur engine when its cold?

 

so that the engine is at optimal temp- running lubricant cold isnt quite lubbing ! could break some thing or cause more wear !

 

so you can hit vtak as soon as you pull out of your driveway

expletive that! I'm hitting mad 3rd gear veetak reversing out of my driveway!


No but really, it's so optimal operating temp etc is reached like the other guys said. This reduces ware and tear on the engine a bit. It's just better for your engine to run at a certain temp, and when it's cold outside that temp is harder to reach.

Wow you got the special edition w/ 3 reverse gears?!

And yea I let the car warm up cuz the manual says so. Allows things to reach a more optimal temp before the engine is under greater load (in gear moving the car).

and your o2 will have a chance to warm up too, this will put you in closed loop mode where the ecu has better control of the engine.

 

I normally let it warm up for 2-3mins, it would prob take a gd 8-10mins for it to warm up.

 

i usually just give it 15-30 sec of idle before I drive, but I don't break 3k until my temp needle starts to move, and I don't hit vtec until i'm at normal operating temp.

 

sounds like a good method- i usually go by how far i have driven lol- once i reach the freeway from my house its open season ( 3.3 miles) on a cold as winter day i find to be plenty fine for hitting my sohc vtec lol

 

my car takes forever to warm up, and I don't know why. 3.3 miles isn't anywhere near enough for my car to even start to warm up (unless I'm going 5 mph). Its an h22 on a sohc radiator (civic dx style), its crazy.

 

It could have to do with you mixture of water/coolant . they recommend a 50/50 .. but i use more like 66% coolant 33% water.. -- when im at the track i run 100% water but that burns up to quickly . running the h22 i would go with a del sol dual row really if i were you i ran an h22 in a 97 accord before and even that was cooling nightmare using the accord radiator

Since '92 Civics have a heated oxygen sensor so you o2 sensor is already warm when you first start.

 

i'm about 2/3rds cooland, 1/3 water too. Been driving on this radiator for a year and a half now. No overheating at all. The needle hits operating temp, and does not move no matter how hard i drive it. Its not what radiator you have, but what condition its in.

its not warm the moment you start your car, and it takes more time than that to get into closed loop mode, which is the important part.

You cant hit vtec untill your at normal operating temp. ECU says "nono" and shakes its finger at you.

I can once my temp needle begins to move (thermostat opens), which is about 5 min before I hit operating temp in my car.

 

do you whipe your shoes off before you enter your house?

Same concept. It's a good habit but not exactly something you have to do.

Another analogy would be like stretching before you excersise. Your car will perform better when nice and warmed up!

thats what i do.. usually im in a rush and jus go go outta the drive way but i try to keep the idle low between 2-4k until the engine seems normal..

 

I wouldn't let it idle in the driveway for more then a minute. Sure it's better to have the engine warmer but at what cost. Idleing will leave a lot of condensation in your exhaust and cause it to rust out. Also when idling you are not getting too much oil pressure.

Cars usually warm up best 30seconds-1min idling and then driven under "light" load until warm.

If you are really worried just get a block heater or a funky magnetic oil pan heater.


Hellz on my old vw on really cold days if would take a good mile before all 4 pistons were firing. Man does a car shake when only working on 3 out of 4....lol


Some people let it warm up for longer cause they enjoy getting in a car that is warm and don't like all the windows icing up on the inside (winter driving)

 

Hell it takes my car like 2min to warm up or about 2 miles

 

I start the car, let it idle for about 20 seconds, then drive on it easy. Not too much throttle, not too much rpm, not too much load.
