Longest time you left your Yaris engine running

[sidewinder]

Do not worry about damaging your engine, with it idleing for 1.5 hours in temps that low. The worse thing that you probably did was build up a little bit of carbon deposits. If you ran the car every day idling that long you could clog your cat converter.Take it out on the highway and clean it out a little bit.
I have worked on engines all my life, every thing from car engines, diesels, to jet engines and as long as your cooling system works properly you won't hurt the car. With the extra cold weather we get in New England, you need to properly warm your car up. Today was 5 degrees out and I warmed mine for about 5 minutes before driving off. Good luck with your car and put your mind to rest.

I do the same thing even when I'm getting gas. I'll take the keys out but still crack open a window...you never know what can happen, right?

the car idling for that long period of time is not beneficial . I highly suggest that you get your oil changed soon as possible . Long idling can lead to fuel dilution , which can thin the oil , thus leading to premature wear . GOOD LUCK

if you leave a car running for long period of time it can lead to valvetrain damage , rings , or other due to the extreme heat . That's why you have a cooling fan , which is no substitute for air passing through the radiator at faster speeds . An acquantance left his new MUSTANG running all night in the garage and noticed smoke would come out of tailpipe when started after the mishap , most likely from overheating the valves or piston rings or both . He decided to trade it in for a new COROLLA . Figured let someone else deal with what may occur further down the road .

another thing that could be damaged is the catalytic converter(s) or other parts of the emission system that would lead to poor performance , such as rough idle ,etc..

I never expected that from a fellow MM owner!!!
Glad no one messed with it. That's got to be a weird feeling thinking
you lost the keys.

I would not sweat it. The Yaris engine is bulletproof. 1.5 hours is nothing. Now if you left it idling for days until an dentire gas tank ran out, that might be one thing, but this engine is built for survival.

i idle here and there when i want heat working on audio in the car... no issues here

[cleong]

You guys are amazingly anal about the car. Heat may build up at idle but its winter over there. Its probably less stressful on the engine to be at 0mph and idling at 600rpm for two hours than to be sitting on 70mph and 3500rpm. Remember, the engine still has a thermal fan that turns on when water temps get too high. It takes care of itself; you only need to keep it fed with fuel and serviced regularly.

not gooooood..............engine feels different now.....

Probably overheated and burned out your cataylitic converter.

I've ran my car has ran for 5 hrs at a time.... but when driving a constant 70mph....

I don't understand how idling for 1/3 the time can be any where near the wear & tear that driving highway speeds is.


It is all in your head.

when you drive at highway speeds the water pump circulates the coolant throughout the engine block faster that then passes into the radiator which cools the coolant that then recylces picking up the heat caused by friction within your engine . The wind that passes around your engine helps cool as well . When idling , this is not possibly ( relies on the fan ) . This is why it's mentioned in owners manual to change oil sooner if stop and go driving or when towing , called SEVERE CONDITIONS . Beileve me I've learned by experience . Heavily relied on cars for our income . CHANGE THE OIL SOON AS POSSIBLE .

Don't waste your money, you DON'T need an oil change...

About 5 hours on a trip to Tennessee

Fifth gear showed on one of their eps the testing a ford focus ST goes through. It was 100000miles at full throttle (6000rpm)

i think 1.5hrs idling is not going to kill the yaris hehe
