Hitching a boat-trailer or camper
to a vehicle not only dramatically
increases the work load placed on its
engine, transmission, suspension
and brakes, but it is expected to cope
with these additional burdens during
the heat of summer, often on roads
made busy by holiday weekend
travellers.
To be safe, rather than sorry, and
ensure you arrive at your summer
destination you need to know your
vehicle is up to the towing task
you’re asking of it and that it has
been properly maintained to ensure
reliability.
The starting point should be
selecting a vehicle that can get the
job done.
An underpowered, and even
worse, under braked vehicle is an
accident waiting to happen, and so is
a vehicle whose suspension isn’t up
to the job of delivering stability
while towing. Vehicle, trailer and
RV manufacturers have the
knowledge to help you choose a
suitable vehicle and any special
towing option packages you’ll
need.
But often your current vehicle can
be upgraded to include these
features by fitting aftermarket
products such as heavy duty or load-
leveling type suspension
components, wiring for trailer
lighting and brake systems,
provisions to mount the correct
hitch, and such things as oil and
transmission fluid coolers.
Before setting off on a towing
holiday, with either a new or older
vehicle, however, a full maintenance
and inspection should be per-
formed, even if it’s a bit ahead of
schedule.
An oil and filter change is
essential, but the fluid in either
manual or automatic transmissions
and in the rear end of rear-drive
vehicles should also be replaced.
Much of the additional strain of
trailer towing is directed at the
automatic transmission. Generating
heat is one of the unfortunate
byproducts of an automatic
transmission’s operation, and too
much of it is one of the leading
reasons they develop problems.
To help extend fluid life virtually
every automatic transmission comes
with its own fluid cooler, which is
usually incorporated into the engine
coolant radiator. This keeps the fluid
within a reasonable operating range
under ideal conditions, but trailer
towing can send temperatures
soaring. Changing the fluid
regularly, or switching (where
possible) to some of the new high
tech fluids on the market can help,
but what you may need is an
auxiliary fluid cooler.
You can also have a similar type of
auxiliary radiator installed to cool
your engine’s lubricating oil, which
can also become overheated and
break down, due to the increased
heat generated
by
trailer towing. Ask an expert about
these
units.
The
cooling
system
should
be
pressure checked for leaks and all
hoses, connections and fan and
water pump drive belts checked.
Coolant is often referred to as anti-
freeze, but that is only one of its
roles. Its chemical makeup prevents
corrosion and provides consistent
performance at the high
temperatures generated by today’s
engines.
The braking system will be
heavily stressed by even a relatively
light trailer and should be inspected
for both pad and brake shoe wear,
but also to detect rusted or damaged
mechanical components. Brake lines
should be inspected, and brake fluid
changed if required. Old brake fluid
can contain moisture which can boil
in the lines under heavy or extended
braking and cause brake failure.
The battery and charging system
and the trailer wiring connections
should also be looked at. Hot
summer weather is actually harder
on battery health than the cold of
winter. Fitting a heavy duty
battery to meet additional
lighting loads is often a good
idea.
The additional weight of a
trailer can put severe loads on a
vehicle’s suspension so the
steering system, shock
absorbers/struts and suspension
bushings need to be in top shape to
ensure control. An inspection will
also reveal any damaged or worn
suspension components.
Tire condition should obviously
be checked, and tires inflated to the
recommended pressures. Low tire
pressures cause overheating and
eventual tire failure, as well as short
life and added fuel costs. Unevenly
inflated tires can cause the trailer to
wander. Look for signs of unusual
tread wear, and such things as cuts
or cracks in the sidewalls.
Needless to say you should carry a
spare tire, and the equipment - jack,
proper sized lug nut wrench - you
need to replace a tire. Lubricate the
lug nuts occasionally to ensure they
aren’t frozen in place with rust.
Filters should also be inspected
and if necessary replaced. A dirty air
filter can both rob power that’s
needed to handle the additional
strain of towing, but also seriously
reduce fuel economy. When you are
travelling you may be forced to
refuel at rather dubious places, so a
fresh fuel filter will keep any dirt
from affecting your fuel injection
system.
Even lubrication of minor moving
parts pays dividends. Under-
lubricated and sticky release
mechanisms have been known to
allow hoods to fly open at highway
speeds.
And don’t forget the trailer or
camper needs maintenance as well.
Good advice before setting out on
the season’s first trip is to hook up
and check and lubricate all the
connections. Then ensure all the
running, brake and signal lights are
working, and look over the wiring
harness for loose connections or
dragging wires. Electrical
connectors should be treated against
corrosion.
Give the trailer’s frame a visual
once-over, looking for cracks,
particularly around suspension
mounting points and welds. Keeping
the trailer clean and painted will
help when it comes to spotting
problems. A pre-trip inspection
should include making sure the hitch
is solidly attached with fasteners
correctly torqued and all fittings
properly adjusted.
