5.3 care of engine when cold

[00Silverado4x4]

Yea 5-30w RP made my piston slap go away. Much quieter at idle. I let mine idle 10-20, minutes before i drive mine

10-20 minutes??? That seems excessive to me. As j-ten-ner said I just wait for the RPMs to drop down a bit then I go. I'll take it easy for the first mile or so but then I drive as I normally would.

Start it, drive it. Worked for the 265,000 miles I put on mine.

 

 

Like stated earlier though, it's like YOU exercising. You wouldn't sleep for 8 hours and then land on your feet and run a marathon race. Take a lil bit to get things moving, then go for it.

^^^ This.

 

The engine warms up faster driving than idling anyway.

It's not about warming up the coolant so that you can have warm air coming out the vents.. I'm referring to warming up the fluids and keeping the pressures down. Let that fluid circulate a little bit before you add RPMs to the engine is all I'm saying. But enough said.

[Jsdirt]

That's what I meant too. Just drive it - keep your foot out of it for the first 5 minutes, and you'll be fine.

 

Cold don't bother me - it's cold in MA 9 months out of the year!

The question is not to warm the engine up or not. It's about driving rpm.

 

Wait at least 'til the idle rpm go down before shifting into gear. Less stress on the trans imo.

I don't rev the engine higher than 2000rpm when I start driving. And actually I don't need more to accelerate quick enough.

 

so long

I follow the exact same regiment. To a T. I let the idle go down to normal, shift into gear, count to 2 one-thousand, then keep it below 2000 rpm for a little while.
