You might have loose connections or low cells on your battery. Check the cells on the battery and if they are low fill them with distilled water only. Also make sure your alternator is giving the battery a good charge.
I had a situation where the security module(under the passenger seat) was drawing from the battery when the car was sitting. I removed it and the draw on the battery stopped, had to buy a new battery because the draw depleted the battery so bad over the winter that the cells died.
A snowmobile can be driven off-road in the winter.
no, I don't.
Yes. it might be, i am unsure, never driven it myself
All cars can be driven without a thermostat. The thermostat is used to heat the car in winter by forcing the water temperature up.
Sure you can remove it and store it.
Not it it is a good battery. I suggest if you are going to let it set for an entire winter, disconnect the positive battery cable. It should be fine if it is a good battery that is fully charged. You might want to put a charger on it next spring just before trying to start the engine after you reconnect the positive cable.
No. Freezing a battery will damage it. have you tested it? The worst environment for any battery is COLD. That is why there are so many problems with car batteries in the Winter. If the electrolyte in the battery freezes, it will usually expand and crack the battery case or distort the plates in the battery
5w30 is recommended for year round use by nissan. if the outside temperature stays above 0 then 10w30 can be used.
Check the battery in the remote.
Keep it charged and it will not freeze. A 1 amp trickle charger works well on a stored battery in the winter.
I own a 2001 maxima se and put 1995 rims on it during the winter. You can do the oposit.
