Warming up your car in winter....?!?

While the Camry and GTI stay ice and frost free in the garage, the truck does not. I don't care if it's wasting fuel, it is getting warmed up to clear the windows. It also has real bad piston slap that sounds like the block is going to blow apart when it's cold and warming it up quiets that. It's also almost impossible to get it in 2nd gear below 30* and you don't warm it up.
 
In cold weather or first starting in the morning, I wait for 20 seconds to allow the synthetic oil to get to the top of the engine, then I leave, in cold weather driving slower to give the transmission time to be able to shift in to high gear before I hit the highway.

That's a common GM "feature" of that era, wrist pins & pistons slapping furiously when they're cold, my MGM has it too (to a not severe extent, just a little racket). Just a reminder to not beat on it until it's warmed up (& things have expanded enough)-or risk something important cracking & breaking off...
 
I do believe in taking care of my vehicles, but they are still just tools (expensive ones) to make my life easier. Like most members here, I tend to be overboard on regular maintenance compared to "normal people". If I had a garage, whatever vehicle I am driving would be parked in it. I don't though. So I warm my cars up if there is frost or snow.

My '01 Civic takes a long time to warm up to sufficiently defrost the windshield; close to 5-10 mins of driving on a 20 degree day. But 10 or 15 minutes of idling while I'm getting ready for work cuts that down considerably. It won't get "warm" idling (temp gauge will not move) , but will still defrost the windshield. My Frontier will be blowing warm air from a dead cold start within the first mile of driving. So it doesn't need a long time to idle to clear the windshield. I don't warm up my cars if the windshield is clear. I crank them, put on my seatbelt, and go easy until they're warm. My commute also doesn't consist of freeway driving. Most of it is under 45mph.

Is idling an engine "good" for them? Probably not. But I bought my cars to take care of me, not the other way around.

I think your remote start is broken, wired wrong, or mis-configured. That is NOT normal behavior with any remote-start I've ever heard of. Most will shut off if you put your foot on the brake before inserting and turning the key. That is an anti-theft arrangement (and takes getting used to).


I presume it's in a Toyota, if that's the case, it's 100% normal and working properly. Pretty stupid to program it that way, but that's they way Toyota programs their remote start systems. Perhaps it is to discourage their use?

I'm just 3 1/2 years away from retirement, and spending winters in Florida at that point, so warming up my car will be a thing of the past. But for now, I have a habit of letting my Honda reach a coolant temp of about 50F before pulling away. That's usually only about 30 seconds but if it's extremely cold it might be a minute. I don't believe it letting it idle for 15-20 minutes though, I'd never do that.
 
I don't like wasting the fuel. I usually start and go. Maybe let ir run for a minute or two while I scrape the windows.
 
Electric warmed seats and steering wheel have changed the game.

On a real cold start I let it warm up while I scrape. Trying to be easy on your engine won't matter if you wreck the car because of reduced visibility.

I saw the follow-up post from the person with the Highlander and theirs does the same. That's really strange behavior.... More of an annoyance than anything (and wear on the battery and starter).

Could you disconnect the door switch to bypass this ? Used to be a plunger-type mechanism that primarily was used to turn on the interior lights (I think). Now many cars seem to have this function built into the door handle so they turn on when you pull the handle.

Yes. On a cold day, it's pretty much impossible to warm up our Civic by idling. If I'm driving it and stop at a stop light, I can watch the temperature slowly drop as the car sits there.

Modern engines are becoming so efficient that they just don't produce enough waste heat to warm up without load. I believe the diesel version of our Forester has an electric heater for that reason.

This is why I do my warm up with the heater off. Then once hot water is available, you can quickly defrost and go.

Some cars are also water jacketing the exhaust and water cooling the alternator so they have enough heat.

In my experience most engines will only warm up so much when idling in cold temps. If its really cold (say -20F) they seem to hit a wall and only get so warm. They really don't "fully" warm up till their driven. Even after hitting operating coolant temp, the engine oil takes awhile to catch up (and the transmission even longer).
 
For:
> -20C (-4F) and colder, the block heater gets plugged in 3-4 hours prior to start up.
> 0C (32F) to -19C (-2.2F), I let it idle long enough to clear the frost from the inside and clear the outside.

For any temperature below 0C (32F) after the above conditions are met I idle drive through the neighborhood to get all the components working and then ease into the throttle after that. None of my engines see past 50% of redline unless coolant and oil etc is fully warmed.

Heck, even driving sometimes it never gets warm enough even when driven. Around 15*F or so I have to block off the grille (S10) to keep heat in it. Going down the mountain you can watch (and feel) the temperature go down. My VW does this too.

Funny you say that. 2:40 is my wake up time, and I have to MOVE to hit the workplace 30 min. later,
 
For what ever it is or is not worth ..........

A late Uncle of mine owned and drove gasoline ( mostly Chevy & GMC ) semi trucks hauling grain . He did most of his own maintenance / repairs . All money was coming out of his back pocket .

He was driving carbonated vehicles , late 1960's , maybe early 1970's . Would get around 300,000 miles out of an engine .

His SOP ( especially in cold weather ) was go out to the truck and start it . He had a block of wood , cut the proper length , so he could prop the throttle / gas pedal open to run the engine at about a 1500 RPM idle .

He would go back in the house & drink another cup of coffee for 15 - 20 minutes . Then go back out to the truck and take off ( after checking the tires , etc. ) .

Seemed to work for him .
 
This is more true than false. Fuel doesn't atomize well when cold and so condenses inside your intake and, indeed, on the cylinder walls. The idea is that by driving off right away you spend less time with the innards of the engine being cold enough for this to happen./quote]

okay...higher fuel dilution of the oil; good reason to do 3k-3.5k mile oci's vs 4.5k-5k mile oci's with 'conventional' oil in my vehicle during the winter...especially since it is rare for my commutes/errand runs to last longer than 20 minutes which reduces chance that oil always reaches normal operating temps
 
We're right on time for the numerous threads about the same subject this time of year....and the same people letting us know which camp they live in. Good stuff.
