Warm up or not?

I don't drive full-throttle before the engine is up to op temp and thoroughly heat-soaked, but the only warm-up time I give it is however long it takes me to finish getting situated (put in a CD or choose a radio station, buckle up, check to make sure I didn't forget anything, put truck in gear).

 

I usually get in, release e-brake, as I am already rolling down the hill bump the starter and floor it!

 

If I have the time I let the RPM go down. If my kids are
Creating a fuss I wait up 5 unless.'if my wife is dealing with the meltdown I shut down.'if
I run into the grocery store or other and i don't want to got through the ordeal of dealing with a 3yo and 2yo and it's too hot or cold I'll leave it running for as long as it takes.

I use synthetic and drop the oil every 5k. That is where synthetic oil does it's job.

Anyway the oil cooler especially with a tow package plus the radiator will deal with the heat. Off roading creats more heat so those who claim it's bad for the engine to idle are drowning themselves I a glass of water

 

First, with engine oil the way it is now a days, especially with Synthetics your oil isn't like molasses at all. That's why you purchase 5w30. Or if you're in Canada, Toyota recommends 0w30 if you can find it.

Second if you're in cold weather there is this brand new device out called a block heater. You plug your vehicle in for the night and this little element keeps your engine block toasty warm till you go to start it.

Read and learn knave.

And the worst thing you can probably do to an engine is poop in the cylinders, light the engine on fire with thermite and for the coup de gras, drop this on it.




Jesus, the lack of mechanical understanding here is dumbfounding. Now I see how elected officials actually make it into political office.

 

Next thing you know, we'll have people pouring tranny fluid into their coolant reservoir...

 

But I was told it helps to warm up your engine faster

 

What's the procedure for escaping from vampires? They scare me more than the zombies.

 

Krazie , that piece was written by the smelly hippies. I don't believe the Enviro Extremists

 

Spring, Summer and Fall I wait till the RPM's drop as a minimum but usually longer while I'm putting stuff in the truck. Winter below 30F I use a oil pan heater and run it til it is warm enough to sit in. Don't know if this is correct or good or bad but that is what I do.

 

Now that beats even my neighbors start procedure!

Seriously though I was always taught that it's really more the internal parts like valves, rings, bearings and all that fancy stuff that should be coming up to temp for proper tolerances before putting a heavy load on a cold engine. I don't think oil is what we should be disscussing if we are all using the proper weight for a particular climate. But please educate me guys...

 

Nah, you're right on. But the point is, idling is slower way to get up to temp, and has other undesirable results as well (less complete combustion, which means more byproduct buildup and oil contamination).

You SHOULD wait until operating temp to put HEAVY load on an engine. However, LIGHT load, i.e. gentle acceleration in normal driving, is the best way to bring your engine up to operating temperature with the least delay.

 

I figure that being I tow a trailer with about 2200 lbs GVW almost every day, I give her just a couple minutes extra to warm up before I go. I guess that would be considered a load right? Without the trailer I just drive a little easy until the temp comes up to normal or might let her run just a few to defrost the windsheild before I go, but that's just so I can see!

Great info, thanks Guys!

 

Even though it was, and I knew someone was going to harp on that, the science is still sound regardless.

But what the fuck do I know? I've only run vehicles in temperatures of -50ºC for years on end, diesel and gas engines.

Just like I'm the only one on my ambulance service that lets the rigs run for a while after using them to let the intercooler draw the heat away from the engine block so it doesn't roast the internals due to the heat from the turbo.

Thanks ya bugger.

 

By saying the oil is like molasses when its cold was just a figure of speech. I have enough mechanical knowledge to know how to build a truck from the ground up. I have a block heater installed but I let It warm up about 3 mins. This thread wasn't started to find out the fastest way to warm up your truck it was started to see who was doing it and why.

 

I let it warm up until the needle crosses the bottom line with the "C"

 

Hey your low on gas if you didn't notice....
