My G has been sitting in the cold garage for 7 days because of snow, i know this might sound like a really stupid question but would it be unwise not to start the car and just leave it there? Or should I just start it for a bit and let the engine warm up?

 

Lets start with how long do you plan on letting it sit?

 

One week is really not that much. If the car is going to sit for real long periods of time (like a few months), you should definitely remove the battery and put it on a battery tender. Add some extra air pressure to the tires too so that they don't get flat spots.

It is good to start it up every once in a while though too, warm it up to full operating temperature, and make sure you use both the heat and the A/C. Corrosion in the cooling system can be a problem when a vehicle sits for extended periods of time.

 

My car frequently sits for a week/10days.

Is it good? Probably not.

Just make sure you get it on the intersate/long drive for at least 30 mins every month. This must be high speed driving not stop and go. Reason: things like diff/trans won't get to operating temp

 

Locked in a warm gagage while it's cold/freezing outside, just get a "Battery Tender" until you can take her out for a drive....Gary

 

A week is fine. I have done that a few times. Like everyone been saying you might want to get a battery tender. You should be able to let it sit longer before the batter dies but your going to need to really drive the car for a while to recharge the battery.

 

Mines been sitting for a month now, sounds like **** when I started it. But I think it just need to get on the road because it was perfect when I parked it.

 

Mine sits for several months every year...no big deal unhook the negative cable or get a battery tender if you leave it sit for over 2weeks.

 

Like everyone said. One week isn't a big deal. When I go on vacation I leave the car in the garage and it's fine when I'm back for just a week. For long periods of time it helps to have it run for 30-45 min as well as the heating/cooling system. I have a friend who has no wheels or suspension with a sitting car for over a year now, and he just let's it run two times a week in the garage and all works just fine.
