Cold weather coming
 

I have an 04 Jetta TDi wagon. I am about to go through my first Montana winter and wonder if I should put a block heater or oil pan heater on it? Does anyone know if this model comes with a block heater already. I cant seem to find a plug in? Iam planing to store it Nov and decemeber in a storage garage while Iam away for the holidays. Any advice on how best to store it. (Gas stabilizers, antifreeze additives etc). Thank you thank you!
