Warming up the engine

X2!

Turn the key, put seatbelt on, set radio, and I'm off....

 

A minute or less in the summer but I let it warm up in the winter.

 

x2

 

I put on the seatbelt and this gives it a few seconds after start up to warm up. then I take it easy for a few miles and never go over 55 right after cranking the vehicle. folks who live on major roads and have to take off like crazy to avoid being crashed into and spilling their morning coffee must really put a beating on their engines.

I hear the damage occurring when some people take off wide open from a cold start and the engine is clanking and clacking like hell and making a really funk smell. not good at all

 

i just start the truck, start playing some music and drive.

 

Just a few seconds.. long enough to get the oil pressure up. With such low viscosity engine oil in the tacos, it doesn't seem necessary for a "warm-up" period.

 

^ that is correct. the oil is like water and moves very quickly/freely to lubricate and protect

 

i agree i let the idle drop then go

 

seat belt, radio, sunglasses, drive... in that order

Maybe 30 secs tops before I'm moving.

 

in my opinion it all depends on the temperature outside.
10 F or greater little to no warm up needed.
Around 0 F i would allow it to warm up for a few minutes.
And by -20 F or colder i would give it as much time as it needs!

Before your engine starts all the parts are at the same temperature (outside temperature, unless your vehicles plugged in).
When you start it different parts of the engine heat up and expand at different rates. If your applying load when the pieces dont fit it could wear it out faster. Also you want the coolant to be relatively warm to so its not thermal shocking anything that is warming up. And as long as the oil is rated for the temperature it should be fine but the warmer the better.

I know where i work the mechanics are very fusy with the start ups of our big diesel engines. The one has heated coolant continuously flowing through the unit when its off to keep it at a decent starting temp. The other one the coolant heater isnt used and the mechanics weren't 2 happy! [because during startups is when the most wear occurs, but these are emergency generators so its different obviously].

anyways i donno if im right, just my opinion.
cheers

 

I generally just let it warm up until the idle drops. This allows time for the cab to get some heat if it's cold out side, and I just prefer to let it idle down before throwing it in gear and going. Usually only takes 20-30 seconds.

Usually by January or February (our coldest months) when the temp hits -40F or colder, I'll let it warm up for about 20-30 minutes. I know the engine doesn't need that much time, but you try driving the truck without heat in the cab when it's that cold. Also, you have to drive it real easy for a good half mile to get your tires to be shaped like a circle again.

Plus, gotta plug it in when it's 20F or colder. Battery Pad, Transmission heater, oil pan heater, and block heater ftw!

 

I let the idle drop first,and to make sure the oil gets all in there and then i go. Even though the 1gr has squirters in the engine that squirts oil up there i still wait a few seconds before i take off.

 

Bad for the engine as well. If the truck is just sitting there, that is the minimum load on the engine and it takes the least fuel to maintain RPM. And while cold, it runs richer. The extra gas on cold cylinder walls tends to dilute cylinder wall lubrication resulting in increased wear. That extra gas is also hard on the catalytic converter. The engine will reach operating temperature more quickly if you drive off as soon as oil pressure is up and that takes only a few of seconds.

Of course if you need to clear fog or frost off the windshield to see, warm up enough to do that. But you don't want to get the cabin toasty warm before you drive off.

I'm surprised by how that engine roars when I first start. I've gotten into the habit of cranking before I buckle up to give it an extra couple of seconds. But it doesn't seem to lurch when I first put it in drive so I think all is well.

 

I let it idle a little bit ... i have that deisel engine mentality tho ... and i told my gf to let it idle also a good two minutes ... than drive off slow so the transmission fluid gets time to warm up before driving normal... thats what truckers do anyways and there engines turns over the million mark

 

We have heavy snow every morning and truck is like frozen. Should I let it warm up or no need in such conditions ???

 

Diesel engines do not require cold enrichment. And they're designed and maintained differently from what is in our Tacos.

 

Just enough to get the oil circulating.

 

about a minute, unless its really cold.

 

Honestly it all depends on the sound, LOL. When it's REALLY cold out and you can just hear stuff sounding "cold" (hard to describe unless you hear it), I'll let my vehicles run for a couple of minutes just to get everything warmed up and "loose". I'm talking temps like -30C and colder. Then it's REALLY easy on everything until it starts to warm up. Easy on the gas, easy on the brakes, etc.

If it's not that cold out, I just get in, start up, buckle up, get the radio going and drive off. Again, nothing crazy as far as acceleration until it gets up to normal temps, but I don't tend to let the car run for minutes on end. I find it gets warmer much quicker if you just start driving it anyway. Between the winter jacket and good gloves, it' no big deal to ride it out for a minute or two while she warms up.

 

Life ceases to exist in Florida at anything below -10C. At -20C midwesterners put their best coat on, cover their ears and stay the hell inside! At -30 Folk from BC let their truck run for a couple minutes before driving off.
