Warming up 5vz-fe

What temperature should I let my 5vz-fe warm up to in the mornings. I have an ultragauge and when I start it up it reads anywhere from 50-70 degrees. This morning I let it warm up to 110' and it seemed to run decent.

What are yalls thoughts on this?

 

As long as you don't go drag race right after start up, I agree with whipper.

 

Not the same engine here, but I have done this with most of my newer Toyotas. I let mine run for about 30 seconds, or until you can hear the sound of the motor change, indicating that oil has reached the top of the engine. You just want to avoid putting load on the engine until things are lubed.

 

For autos, I let it run a few mins (remote start in the morning) because I dont like how the tranny wont shift into 3rd gear until 35mph when cold.

 

In the summer I let it run about 5 - 10 seconds. In the winter I wait till the fan clutch disengages (roaring goes away).

 

Back when I was a kid my auto shop told us that the important part of a cold start up is to give the engine enough time to get the oil circulating off the bottom of the pan. To this day I still give the engine about 15-20 seconds for the oil to get moving. Not sure if it makes a difference. I am more weary about making sure there is proper oil pressure than if the engine is "warm" enough.

 

Wow, is that the fan clutch? I thought the roaring was the engine not having oil in the top. You learned me sumthin.

 

I let the engine run for 10 seconds. That is plenty of time for the oil in a properly operating engine with correct oil quantity to reach all the critical areas. The only exception for me is a turbocharged engine, which I let warm up and cool down for at least 30 seconds.

 

I just let it run til it drops a little rpms. When i start it it stays at like 1800-2000 rpms and once it dies down to 1300 i go

 

lol nice. You will hear a slight amount of valve tap right at startup which is a lack of oil at the top but it goes away almost instantly.

 

Ask any mechanic, let the engine run a minimum of 30 second in the summer and minimum of 60 seconds in the winter. If not, the engine will develop knocking and ticking later on it the engine life (100k plus miles)

 

It's all personal preference. I let mine warm up just in case. Unless, someone is chasing me with a gun, then I roll.

 

That's exactly why we have a winter weight and summer weight oil. It's designed to compensate to flow better in the cold.

 

Glad im not the only one!

 

I usually let it run about 30 seconds or so since i'm still getting myself situated inside anyway (putting my work stuff, lunch, seatbelt, etc).

 

ya i dont let it sit and run for a good couple a minutes like i used to let my chevelle do but i still give it up to 30 seconds max then im outy 5000 pimp.

haha but in all seriousness id say a good 15-20 seconds is enough for the rpms to lower. helps to let it run as youre getting situated like the person on the last page mentioned. thats what i do

 

Tho the oil pressure could come up in 1/2 of a second of start. 10 seconds more more than enough time to oil to reach all parts of the engine. Just keep rpms low which you should anyway.

Todays engines have changed so much tho there are tighter than say 70s or 60s but the main thing that has advance beyond engines today is OIL. YES oil is way advance of engines today. There is so much r&d to oil is not even FUNNY anymore. Ever notice why if you spill some on the ground how long it take to become dry? Think about it.

 

I thought it was to warm the tranny fluid . Either way, I still dont like it

 

I usually let it run for 30 seconds or so in the summer time if it's been sitting all night. In the winter I run it for probably 15 minutes every morning. But we have unique winter weather

 

I like to let mine warm up for a few minutes in the AM. Other than the fact it drives smoother after a few minute warm up my opinion is engine components are manufactured with specific tolerances that allow for expansion of parts with optimum tolerances achieved when the engine reaches normal operating temperature.

The majority of engine wear and tear sill take place in the first few minutes. So idling at a steady 1000 rpm sounds easier on the engine than the fluctuations experienced shifting through the gears on a totally cold engine.
