Hey all, coming from an automatic 4cylinder i would always let it warm up for about 5 or so minutes before taking off. But as for these cars i see some people buy 160* thermostats and what not, so im a little confused.
Is it necessary to let these cars warm up? Do you personally let it?
sorry if this is kind of a dumb question.

Knock sensors engage at 160, the car needs to warm up a fair bit. At least close to the second line before you really reef on it. No motor likes to be beat on when it's cold, but a five minute warmup is not needed. These cars heat up pretty quick. Anyone who runs a 160 tstat is riding a very fine line.

No real need to, unless it's extremely cold outside. But like all engines, you shouldn't romp on it until the engine is in it's proper operating temp.
And no need to let it cool down like a turbo car either.

so if i jumped in it started it up and backed out my garage instantly, it would be okay? but yeah i never romp on any cold engine ever. i usually drive lightly either way unless im really bored or theres a yellow light lmao. but in my integra i would need to let it warm up or my tranny would get mad at me.

Don't install a 160* thermostat, just leave the stock 195 in there. Anything lower will require a tune and really doesn't gain you anything.

Id wait 10 seconds in the winterdays just for all fluids to go where they are needed. I have a "warm up road" since im in a town of 800 ppl no one is on the road i just idle maybe BARELY touching the gas along for 2 minutes untill i hit the 50 mph zone then i increase to normal speed. I hate idling for 10 minutes waiting for the engine to fully warm while it sucks up gas.

yeah. i guess ill wait like 10-60 seconds every day. i barely waited today and it didnt seem to make a diff. its not really that cold outside yet, but when its cold in stl it doesnt get too cold anyways. compared to other places at least.

I usually let mine warmup for about 5 minutes. Just walk out start it up and go get ready to leave.

This is why I love Southern States... I just jump and go. Give no cares, if she's got fluid shes ready to run.
Side note, were gonna have a cold front end of the week, I'll need a jacket. Gonna be in the 60*s

Still have your owners manual? It advises against letting your engine idle to warm up.
Engine warms up much faster when being driven.
If necessary, use the block heater.
Regardless, for any modern engine, get in and drive. Do not go past half throttle, even less if its cold, until the coolant has been at temp for some time. Even if the coolant is at temp, the oil and the metal engine parts aren't up to temp and expanded to their designed size.
Mainly the oil isn't warmed up, meaning it doesnt provide nearly as much protection as warm oil does.

^ thats the answer I was looking for.
because i've been wondering this for years.
and people make fun of me because i wont move my car until its at least at 160* even then i'm under 1/4throttle till 180*

As Matt5112 said... You don't want to beat on a cold car, but you can/should drive it. The big idea here is the oil needs to get up to temp.

Remote start here... I'm in MI it's a must. I let it run for 5-10min before I takeoff.

That's all I do all day long in the winter season is remote starts.. we do over a dozen dealerships In the area. when someone purchases a new vehicle plus walk ins.... all that on top of our normal electrical diagnoses and repair vehicles lol I don't think I've had a vehicle I didnt have one on lol

ight i always read the "newer engines dont need to warm up" but owning a 1994 i was never so sure, but im glad to know now. 10-30 seconds it is.

I don't necessarily let it warm up, but I do let it idle down a little bit before I take off.
