Vacuum Leak Test
An engine generates vacuum when running, this vacuum is used to operate several
accessories from the temperature control system (heater, air conditioner) to the cruise
control. Testing a vacuum source is simple, remove the vacuum line from any giving
accessory and attach the vacuum gauge. Start engine and allow to idle, the gauge should
read between 14 and 18 inches of vacuum. If a low or no vacuum exits there is blockage
or breakage of a vacuum line. Inspect all vacuum line integrity, then remove vacuum line
from the engine source and check for blockage, repair as needed and recheck the system.
Engine Vacuum Test Kit
Removing Air from the Brake System
Most vacuum test kits are produced with a brake system bleed attachment. Once the
brake bleeder is open attach the vacuum hose over the end of the bleeder fitting. Then use
the fluid storage container inline to the hand vacuum pump. Operate the pump until no air
is present in the line. Remove bleeder hose and tighten the bleeder fitting. Refill the
master cylinder reservoir with brake fluid as needed
