Warm Up and then drive or just Key in and go

This is probably a silly question but its in the back of my head now everyday before I throw it in drive and go.
Since I have gotten the dongle and Torque Pro app, I see the actual temps when I start.

There is a setting that will sound an alarm if your RPM's increase too much before your engine is at operating temp. not even sure what the thresholds are but i have not heard that alarm yet.

Question is what is a good temp to let it warm to before driving?

I live in the desert, ( las Vegas ) so I'm certain warm up time is much shorter than a cold state, but how long do I really need to wait to get to operational temp. I though operating temp was 185-195.

Below are some screen shots of the data.

Lastly all Gens are welcome to Reply since this is relevant on a 5.7 also I assume.

First one is right after startup


Second one is where I let it go to before taking off this morning.

Last one is upon arrival at destination.

 

I don't bother. Start get phone and everything set then go. Less than a minute. I don't hammer on it until it's up to temp but I'm not going to let it run all day in the driveway to get it warm, warms up much quicker by driving.

 

It depends... I let the whine stop before I go, so 30 seconds??, but sometimes I idle for a few minutes and others I just go, depends on the situation....

 

If its summer I let it idle for 2 mins or so, then drive around nice and easy for a little. When its winter time I like to drive around my neighborhood for a couple mins only so I can get my transmission fluid heated up, that's the main thing to be worried about once your engine is good

 

I wait for the oil pressure to come then go.

 

This is from the automotive repair shop I’ve used for many years website’s FAQ

My mechanic says I should let my engine warm up before driving. Is this right and for how long?
Yes, but long warm up periods are unnecessary, because of the viscosity and computer control of the engine. Cold engines will idle at a speed, much higher than an engine that is fully warmed up. Within a few seconds, engine idle will return to normal, and then it is safe to put the vehicle into gear. Pulling a vehicle into gear, with it racing at high idle can cause damage. Normally, 10 to 30 seconds is sufficient or when idle drops below 800 RPM.”

In my 01 it takes a good minute and a half or 2 for the engine idle and oil pressure to go down

 

Summer start and go, but keep RPM’s low until she warms fully in a few minutes.

Winter she gets warmed up for a few minutes. Driving RPM is kept low until full warm up.

 

I try to let the engine coolant temp come up to 100 degrees before launch.

Can not really say why?

 

Let it build oil pressure, then go...maybe wait until the fast idle kicks down, esp. in winter. Saves wear and tear on your U-joints, which I hate to change, and my bendy joints getting under and out from under the truck if I have to change U joints.

 

I let it idle long enough to find a song on the radio. I drive gently until its up to temps. I don't live in a climate that gets very cold so I don't see a reason to mess around burning gas to heat the motor up.

 

My driveway is 3/4 of a mile long, idle out and then let her rippp.....

 

I typically fire it up, then wait for idle to kick down. Seems to be a 30-60 second affair most days. My truck is garage-kept and the garage stays pretty consistently around 55-70° between cold and warm months because it's partially underground.

 

I usually let mine run till it come off high idle, old habits die hard. Remember when you couldn't get the carburetor on your truck to kick down till the spring on the manifold warmed up, and then you had to give it a good kick to the floor?, i do.

 

Turn the key and floor it immediately.








I let it warm up for more than a minute and less than 5. Open door, turn the key, get in it, seatbelt, take down sun visor, plug in phone, set up Pandora on phone, turn on lights if needed, adjust climate control/defogger, put in gear, slowly cruise down the street until the electric choke turns off/idle returns to normal.

There's a lot of oil and a big block of metal to heat up.

 

As long as you don't romp on it when it's really really cold right after starting it, key in and go should be fine.

 

Sounds like I’m the opposite of most. My day starts at 4:00am with me getting in the truck and driving at 4:30am. I wake up, get dressed and remote start my truck while I finish getting ready. By the time I finish everything, it has had 10-20min of warm up time. The shop ‘messed up’ with the remote start timer as I requested it have 15min increments but it will staying running until I turn it off. I don’t like getting into a cold truck so this gives it time to nice and toasty.

I’ve been this way as long as I can remember. I like to give it at least five minutes to get the juices flowing before I start driving it. The first start of the day is always the longest and after that, I only remote start it when I’m walking up to it or trying to signal the old lady it’s time to go... lol.

I’m probably more excessive than most especially comparing my tundra to my Duramax. My Chevy came factory with remote start with only (2) 10 min remote start cycles. After that, you have to start with the key. GM only saw the need for a big diesel engine only being warmed up for 20min at most, so maybe I’m OCD.

 

I try to wait until the loud ass fan in my 07 stops spinning; about a minute, though I ve had several complaints from a few of my neighbors about how loud my truck is. It kind of funny, because it s stock. It s the noise from the fan they are complaining about, so if I have to take off when it s sleeping time for most folks in my apt building I just start it and drive. That being said; any cold engine should be handled with care.

 

Did it look like this?

 

I was taught it's always better to bring the engine up to temp while driving because the engine wears differently under load vs. idle and the wear is more even. I start, let the OP build a little before putting the truck in gear and go. Just don't hammer on it until the temp is up to normal.

 

eh.. unless its like -20 outside i usually just give it a minute and go. don't beat on it until that coolant temps reading 186 on the scan gauge though.

 

IN ALL my rides, I wait till high idle drops. Then drive slow out of hood. By the Time I am at the entrance of hood, I am ready to go.
But I still drive slow till I need to go fast.


7.3 Liter Diesel Ford Super Duty E350 Van- whole different story.


O.S.T.

 

For example, this morning is 37 degrees out, warmup time 5 mins plus easy driving for the first 5 mins

 

I have autostart, so I let it idle for a good couple minutes before I drive. Usually like to see coolant up to 130 or so, but I always like to wait until the idle goes down.

 

I'll start, and it usually takes me a minute to get settled in before I'm ready to drive. When it gets cold, I'll let it warm up a few minutes and drop out of high idle before I drive.

 

40F and higher: Start engine, wait for AIR pump to shut off, drive vehicle and keep RPMS below 3000 until ECT is up to temp.
20F-40F: Start engine, warm up for 5 mins, drive vehicle and keep RPMS below 3000 until ECT is up to temp.
20F and below: Start engine, warm up for 10 mins, drive vehicle and keep RPMS below 3000 until ECT is up to temp.

Also: If I am towing, I always give a minimum 5 min. warm up, regardless of ambient temperature.

 

I'd love to live in a lower-density area where I could do this w/o my vehicle eventually getting stolen.

High density of humans = high probability of opportunistic crime.

 

It is strange but as I get older I am somehow much more tolerant of sitting there waiting in the cold?
I pretty much wait until 100 degrees or when I start getting good heat which used to Kill me but now is just not a big deal?

And same here,there is no letting the car sit running unattended anywhere EVER if you want to see the car again!
