Question

when its really cold my car turns off i know it has to do with the battery and the weird thing is that when its not cold it turns on fine.

Answer 1

if you can't get the engine to rev in order to start the car, when you put the contact, then it's the battery
if the initial revs appear but the engine doesn't fire then it could be the fuel you're using (inappropriate to this season), might be a clog (limiting the access of fuel to the engine, therefore not giving enough power to it) or something else... also check oil type (some oils don't perform that well in winter conditions) also (if diesel) check if a pre-heater is installed on the fuel tank and if it's working (since diesel fuel can sometimes behave badly in very cold conditions)
another cause might be the formation of ice somewhere on the fuel circuit (due to improper access of air into the engine or bad fuel) usually this would explain why it turns off with no reason

Answer 2

that may be the starter; the grease has hardened. It takes position if water receives into the grease - even a pair droplets will turn grease into wax in chilly climate. the undemanding frame of mind is to change the starter, in spite of the undeniable fact that the price (about $450 parts and exertions, customarily $350 for a sturdy starter) is daunting. Rebuilt starters have a terrible acceptance, some not in any respect operating in any respect and too many lack of life contained in the first month, so stay faraway from them altogether. once you've a buddy or buddy of a buddy who works on autos that is a undemanding sufficient activity - eliminate the starter, take it aside and replace the hardened grease with sparkling grease, reassemble and reinstall - that a deal may be worked out. There are not any further a large number of ideas to flow incorrect. EDIT - the reasoning in the back of brushing off the battery and seize safe practices swap are that it will honestly cranks and begins ok, and that you're protecting the seize down at the same time as attempting distinctive cases (besides, it extremely is how I do it). if you try by technique of liberating the seize between tries it could be the safe practices swap. If the starter actual turns somewhat slowly at first and builds up speed it could be a nasty battery - inner connection. The exterior connections oxidize immediately when they commence failing, so it does no longer commence in any respect by technique of now if the exterior connections were at fault. and obviously, batteries develop right into a lot less lively at the same time as chilly - even in spite of the undeniable fact that that isn't your symptom - yet they do no longer freeze if charged. a very charged battery freezes at -77F (first source).

Batteries, especially when they get older, don't work well in the cold.

If it's older than 5 or 6 years, probably time for a new one. Take the old one back to the store for recycling. Hopefully that will fix things.

Good luck.

Answer 4

you might try checking the battery connectors sometimes they can become corroded. Use a metal file or rat-tail file to clean them up then reconnect. The connectors can also become loose so tighten them up. You may have to get a new battery and/or have your alternator checked.
