Question:
Soon winter will be upon us - Is there a
proper way to store your dream car for the
winter?
Answer:
A FEW POINTERS ON WINTER STORAGE
There are many tiers to this - - - the short answer is that the
vehicle should be spotlessly clean - - the oil should be fresh and any fluids such
as brake fluid should be flushed and changed - - - coolant if it has any
should be fresh and changed etc.----- the tire pressure should be at least about 10
pounds above the normal operating pressure to help support the tire carcass
and the car should not sit in the same exact spot It needs to be rolled back
and forth slightly and sit in a different position on the tire - - The best
storage is in a warm (not hot ) dark place with a light cover that can breathe over
the paint work - - - if the environment is dusty then the cover should be a bit
heavier with possibly a plastic cover on top to keep the dust off . The
battery needs periodic charging - -- the easiest way to accomplish this is to
purchase a charger that senses battery condition and automatically switches on and
off; do not leave even the tinniest charger on all the time the battery will
boil dry or at least sustain irreparable damage - - - these chargers are usually
sold by bike shops as motorcycles have the same storage problem with
batteries -- the other method is to monitor the battery and periodically charge it.
You can just disconnect the battery and hope for the best but what sounds good
now will be a potential source of aggravation come the first sunny day in spring
WHY?
Fluids:
The oil should be fresh because oil just doesn't lubricate (see earlier
article on oil ) the oil in the system collects and removes contamination
so we want all the contaminants out when we let the car sit. Brake fluid is
hydroscopic (takes on water ) the water content and contamination content of
the fluid is what eventually damages the seals and components of the brake
system so it is better if it is fresh (it should be changed at least annually anyway
or after each trip to the track ) it wouldn't hurt to have the brake fluid
flushed and changed in spring again as its boiling temperature changes with it
taking on moisture and it takes on moisture when it sits exposed to the
atmosphere -- and last time I looked every brake reservoir in existence has a breather
hole to atmosphere. Coolant can go bad and still test OK so we don't want our
cooling system freezing so fresh is best and we don't want also the contamination
(sediment) of the coolant sitting in one spot in the system potentially
plugging up passage ways that have to cool the engine in spring. Other fluids in the
vehicle are perhaps less critical (power steering fluid, transmission oil)
if they are changed however it doesn't hurt to change them periodically and now
is as good a time as any. Unless there is a component problem the power
steering oil very seldom takes on any contamination and it isn't hydroscopic.
Transmission oil is actually designed to last a long time and doesn't
require too frequent changes (depending on the drive cycle that the vehicle is
subjected to) in the case of an automatic visually inspecting the oil for clarity and
discoloration is sufficient , In the case of hypoid type gear oil the oil
has an additive for differential break in and if you change this stuff too
frequently it can actually cause a breakdown of the gear surface but this is only if
you changed it on a ridiculous frequency-- but needless to say once per year
is more than sufficient.
Tires:
Tires age and they are affected by temperature and light UV breaks the
compound down and they tend to heat age so hot storage will cause the rubber
to get harder. They are also flexible and are made of a fiber carcass saturated
and coated with rubber any flexible polymer has the tendency when it sits
in one place with load on it for an extended period of time to conform to the
surface that it is sitting against if it is the floor then you get a flat
spot forming so a little extra tire pressure will help combat this effect by
making the tire a little more rigid - -- this effect can even occur on some tires
over night depending on the cord construction (rayon belted tires are
particularly bad for this you get a square wheel ride until a bit of temperature gets
into the carcass after the first few miles ). If you periodically move the car a
foot or so and get the pressure point moved this also helps the flat spot not to
develop (once every couple of weeks or so ) the other advantage to the
harder tire pressure is that the vehicle pushes easier. It doesn't hurt to
periodically check the tire pressure as they will loose a bit of air pressure through
seepage and when the temperature drops the air inside shrinks and you need to add
more pressure from this alone.
Blocks or no Blocks: That is the question ! Whether it is nobler to put your car on blocks
or leave it standing lonely on the cool concrete floor . The Idea of
suspending the car to take the weight of the suspension and wheel bearings is more a
consideration of the bearings. What happens is this when the ball in bearing
sits on the outer race with the vehicle weight pressing on it the ball is
slowly pushed through the grease separating the metal of the race and ball and
when they contact you can get a minute mark in the race and or ball on the highly
polished surface of either component and when the bearing starts turning
again you will have a premature failure. So pushing the car forward or back a bit
to help the tires also will cut this phenomena off at the knees. Now there are
exceptions to everything - - if the sitting in one spot bearing is
aggravated by vibration the ball will not just squeeze through the grease but it will
actually micro weld itself to the race surface then break free then weld
again and so on so you can imagine what happens when the bearing is required to
roll again - - it's scrap! If you plan on storing you car near a railway or
in a corner of your Uncles stamping plant you might want to consider blocks or
increase the frequency of rolling the car to every few days. We know about
this phenomena from cars being shipped by rail and tied down too tight where they
couldn't move around and circulate the grease in the bearings.
If a vehicle is going to sit for an extreme amount of time like
years - - springs can take a set but not as much as years ago - - the steels
that are used to day are far superior and unless the time span is long blocking
to save the suspension and springs is probably not necessary for the couple of
months of the winter and the shocks don't know that they are sitting still
unless you spill the beans and tell them.
Paint Exterior
Common sense say's that if you leave debris and dirt sitting on the paint-work for an extended period of time that it will lead to damage to the
surface -- if you move the dirt around you get scratches (check out the hood
or roof of your average leased business coupe you can probably see the sliding
briefcase imprint from across the underground) So it stands to reason that
if you put a cover on dirt it will damage the surface - - clean and polished
before storage is the word for paint and a nice soft cloth cover that won't
scratch - - if there is a situation where dust will accumulate at all you
may want to put a second covering on top to keep the first layer clean and keep
the dust from saturating your nice soft cover. The exterior rubber surfaces of
the vehicle should probably get a coating of whatever magic elixir that you have
discovered in your search through the jungle of products out there that
promise eternal youth to anything flexible. If you have the resources then under
the vehicle will benefit from an oil based spray or reasonable facsimile (that
won't dissolve the factory under coating) This will keep away the evil effects of
condensation on any bolts or hardware (corrosion) to maintain a new just
installed by the factory look . In a storage facility condensation is
probably the no one enemy so a heated but cool place is best or a facility where at
least the effects of the outside temperature fluctuations are dampened. A steel
building with a concrete floor and a cool humid foggy day and anything
metal inside the building will appear to be sweating - - - this is not a good
storage facility - - - insulate the building and it is substantially better - -
add enough heat to take the chill off and we have a winner -- you get the
idea !
The Battery
The little black heavy box filled with engine cranking juice can be quite cranky if it doesn't get all charged up or a good sleep for the winter.
Inside the black box there is a chemical reaction that produces electricity and a
few things can happen to slow down or stop the process over the storage period.
If a battery for instance sits idly on a cold concrete floor the cooling effect
of the concrete can over time chill the reaction and slow it down to a stop and
the battery can go dead as a door nail putting it on a piece of wood or
something as an insulator will help. Another effect that can also drain the battery down
is if the outside of the battery is dirty the dust and dirt can get moist and
the moisture will conduct electricity - - over time even a slight conductivity
over the outside surface of the battery casing will short it out and it will
drain to the point that the reaction inside stops. These days the biggest threat to
the longevity of the battery is the on board electric systems that cars
have - - everything from cell phones and alarm systems to ventilation systems and
clocks that keep demanding even the smallest amount of power from the battery when
the vehicle sits -- So the battery needs to have power put back into it when
we are driving around town the on board charging system does this job quite
nicely but when our toys are sleeping the only way is to periodically charge the
battery. There are battery condition sensing chargers available for a lot
less than the cost of a battery (I think less that 100) that are well worth the
investment you can plug them in to the battery and into the wall and the
next time you touch the plugs is the next time you want to drive the vehicle. The
next best thing is to periodically put a trickle charger on the battery and
charge it up at a rate of about 2 to 3 amps - - just don't forget to take
the charger off - - - the battery can boil dry if neglected once it is full.
There of course if the mess creating method of draining the acid from the battery
and storing it separately in a proper container and storing the battery
dry - - - the battery will last an eternity like this but this is messy and
angerous - - the sulfuric acid inside has to be treated with respect.
The Interior
Like the exterior - - - spotlessly clean is best and a treatment of the favorite leather elixir is best (or vinyl dressing ) and whatever the local
concours winner or her/his detailing shop uses to preserve the carpets and
fabrics that make the inside of the classic special and maybe a moisture
absorbing box of something or other to keep things dry and non moldy or
musty . Oh yeah and environmental tree huggers don't read this it's bad for your
heart. You may need something around the vehicle to keep mice or there little
relatives from nesting in any part of the vehicle they love to chew up
upholstery and the like to make a cozy Connelly leather bed for the winter
and their offspring in the spring they also seem to find delight in chewing
plastics as well like the insulation on wiring etc. A bad incitement for
these little guys is storing any sort of food for the family pet in the same room
or in near proximity to the vehicle you not only provide them with a gourmet
lunch but the most comfortable bed and breakfast in town. We were told that moth
balls would keep these rascals a bay but we have seen them make a nest in the
container of moth balls in the vehicle.
For more long term or permanent storage there are a more considerations
like fogging the cylinders with oil mist etc. and coating different materials
used on the vehicle with a long term preservatives made for the purpose - -
this requires a whole new article.
If any of the above seems too complicated or
confusing sometimes a conversation with the same people that service your
prized possession will also provide a cocoon service where they will (for a fee)
prepare the baby for sleep store and baby sit for the winter and change its
diaper for action in the spring all you have to do is pay and show up
brandishing next years license validation sticker .
