If you’re an environmentalist, zero idle time may be your choice. After all, absolutely no combustion vehicle on the road today has an emission system that operates when the engine is idling. That’s right – none, zero, zilch. Doesn’t matter if it’s a $100,000 luxury sedan, an entry-level subcompact, or a lowly winter beater. At idle, it’s spewing raw, untreated emissions out the tailpipe. And with modern fuel-injected engines, the idle quality and cold throttle response is usually silky smooth, no matter how hard outside temperatures fall. So, why idle to warm up at all?

Top reasons insurance won’t cover you in a crash

  Top reasons insurance won’t cover you in a crash Any dishonesty on your part can result in loss of coverage – but you may not know until it's too lateBut what if you’re doing things that could result in you having no insurance at all? Don’t bother reaching for that little pink slip in your glovebox. It doesn’t mean a thing if the carrier decides you’ve broken any of their cardinal rules. You may be knowingly or unknowingly, putting yourself in jeopardy and leaving yourself without coverage. Some may seem obvious; others may be a surprise to you.

Pick a dry and relatively mild day – anything above freezing will do – and let the vehicle sit in direct sunlight for a short amount of time to let things really warm up . Your Corner Wrench : Should you let your car warm up ? 4.

Your Corner Wrench : Curb these bad driving habits. Warm - ups (not enough or too much): Hard to mull over this debate in the relatively warm weather of summer, but cooler temps are on their way. All the various fluids in a car need time to warm up and flow to avoid things like leaking power-steering

Well, safety first. If you can’t see out of all the windows, let it warm up – and peeking through the porthole-sized patch of glass at the bottom of the windshield doesn’t count. It may take only three minutes or it may take 10, but you don’t belong on any road if you can’t see out of your ride.

If you want to shorten the amount of warm-up time, especially if it’s below – 15°C, use an engine block heater. Even as little as an hour of block-heater time will drastically shorten the engine warm-up period. With most vehicles, you can feel some heat from the HVAC vents as soon as the engine starts if the block heater has been used.

As for how much warm up time a vehicle needs, it doesn’t need much idle time in terms of engine protection. Once the idle steps down off of its cold start speed, the engine oil pressure will be sufficient to operate at road speeds without risk, but the same can’t be said for other systems and components.

You should also verify that your existing wheel wrench kit will fit these wheel nuts, which often come with an anti-theft key adapter socket. If they can’t stand up to a few Canadian winters without looking shabby, they may not be of much value, no matter how low the price.

For instance, automatic transmissions depend on a good volume of fluid flowing to every internal passage in order to provide solid shifts and to minimize wear. Depending on the transmission type and size and outside temps, this can take anywhere from two to 10 minutes of warming up. If your schedule won’t permit a full warming, take it easy on the throttle for the first few blocks of your commute to safeguard the gearbox.

Power steering systems can also be prone to failures when operated without a warm-up. Older lines can develop leaks, as can steering gears and pumps due to the increased pressure than cold fluid can exert. The same can happen to automatic transmission cooler lines.

Letting an engine idle too long is a waste of fuel and produces excessive emissions. If the glass surfaces are clear, you really only need the length a top-40 song on the radio as a guide to warm up time – about three minutes – on snappy days for most vehicles.
