Just moved to NY and its starting to snow. Ill be leaving my car outside in the winter and probably wont be driving it. With the cold weather temperature right now dropping down to 20-30F. Will there be a problem with the plastic gas tank/fuel line/brake line/coolant hoses cracking? If so what can i do? Im from Florida and never had to worried about the winter, this is a first.

 

You should be more concerned about the possibility of the coolant freezing inside the block causing it to crack. Make sure the freezing point of the coolant is -20*C (-4*F) or lower so that you're covered. Other measures you might want to consider are:

1. Lightly smear some Vaseline on the door weatherstrips and the trunk weatherstrip so that ice doesn't get stuck to them.

2. Remove the windshield wipers and protect the windshield and the rear window with cardboard.

3. Remove the battery.

4. If you have a car cover, use it.

5. Inflate all four tires and the spare to 40psi. This will reduce the chance of flat spots forming on the contact patch with the ground due to the weight of the car.

6. Grease the handbrake cable linkages so that they don't freeze and become seized.

 

Thanks im using Ford orange coolant rated -34F to 265F i should be okay. What kind of grease should i be using for the handbrake cable linkage? So plastic gas tank/fuel line/brake line/coolant hoses are safe from cracking?

 

I lived in SE Michigan and drove my Mustangs year round. Through lots of heavy snowstorms and lots of cold weather.Never had any issues with the gas tank or any lines freezing and cracking. I never heard of anyone having any problems either.

 

I wouldn't take the battery out, I would get a battery tender and plug it in 1 week out of the month, that way you don't have to reteach idle and other things first thing when you start it in spring. Get some fuel Stabilizer and put it in it and as close to having a full tank as possible.
Since it is an Automatic don't use the parking brake and a silicone based spray is what I spray my exposed brake cables in the rear with. Also, do not start the car thinking you are going to warm it up, unless you get the engine and transmission up to full operational temperature it does more harm than good.

 

I have driven my '06 GT 'vert all year round as long as I've owned it, bought it new. It now has 180K on the clock.

 

winkawak, The only caution I can add is that a few years ago I forgot to put "Below Freezing" windshield fluid in my 2014 GT holding jug . Do you know what crap you have to go through to replace a cracked windshield wiper fluid holding jug? Other than that the boys have covered it all, I think.
