Hello every body,

After reading and reading through this helpful forum I was able to winterize my car and get use on winter X' reactions , I would like to summerize what I did

A) Exterior: Paint wax and car wash as possible.

B) Locks and doors:
Spray WD-40 from the slide blind cap and white grease.
Spray silicon spray over door rubber and side windows glass edges.

C) Change the upper hose (old) and new antifreeze.

D) Fresh oil change (Dealer charge 95 USD) on December.

E) Full leakage checkup, result radiator lower sensor replacement.

F) Brand new all season tires (Goodyear 285,45, 20")

Also have the following :

A) rough start in really cold weather 0 F , for 2 seconds.
B) Sometimes, whistling sound from the belts, not really bothered from it.
C) Long warm up times, " I warm it up what ever people says, I feel better and hear less sounds"

Please if you have any other advices , don't hestitate to post them , thanks guys
