you start to rely on your A/C service tools and equipment, it's a real good
idea to check and test them now, before the season starts. We've compiled
a complete check list for your review. Here's some details that you will
want to go over:
gauge sets should be checked regularly, not just at the beginning of the
season. They typically go out of calibration and they can even leak.
When the low pressure gauge is out of calibration it makes it really
difficult to get any sort of accurate vacuum reading. Keep in mind that they
have probably been bumped around a few times and who knows how many hot exhaust
manifolds and radiator fans the hoses have been caught in. So it just makes
sense to check and calibrate your
manifold gauges. You can also leak test them using your vacuum pump (just
block the high and low couplers and pull vacuum on the yellow center hose)
After that, you add an ounce of refrigerant to pressure test them. Use a
leak detector or bubble check fluid on all the connections.
you own a charging station, you should be able to do the same sort of inspections
and tests. However, review your Owner's Manual on that equipment for complete
the most overlooked piece of equipment on the floor of every auto A/C service
shop. These pumps require regular oil changes; at least every 15 to
20 hours of operation. As your vacuum pump has probably sat for most of
the winter, it's a good idea to get that oil changed now.
You should seriously consider a complete service

about your vacuum pump's operation, you should review the information we
released that shows you

recovery station has filters that require regular service. You should be
taking the time now to check (and replace) these filters as required.
You may also find that it's a good idea to have a spare on hand. Every
recovery station will be different, so you have to refer to the manufacturer's
information for those details.
couplers can leak over time. You may also find that you require some of those
hard to find adapters and fittings that you need to service particular vehicles.
Check your A/C couplers, fittings
and adapters to be sure you've got what you need.

get caught without the right o-ring, gasket or washer. With the variety of
applications on the road, 4 o-rings sizes will just not give you the coverage
you need. Be sure your o-ring
kits are full and ready for the season.
all of those other items that you reach for every day like

UV Dye and
Leak Detection Fluids? Be
sure that you have a supply so that you can complete those service jobs when
they arrive. (You may want to view this video help on how a
UV enhanced external leak
detection fluid works! These fluid provide another good reliable method
for auto A/C leak detection).
on your leak detector and other tools you use, you know batteries never hold
up through the winter. Double check your supply and be sure you have a supply
of fresh batteries on hand.
