EXPECTED READINGS AND THEIR DEFINITIONS
Gauge readings at idle (read off inner scale):
Idle (less than 1000 RPM) ==> steady needle in the blue zone (Fig. 1)
= GOOD READING
With the engine running at idle expect to see no signifi cant rise in
pressure needle should be steady.
Idle (less than 1000 RPM) ==> needle pressure climbing quickly or an
oscillating needle (Fig. 2) = GAS PRESENT in the block, possible head
gasket failure.
Gauge reading at 2500 to 3000 RPM (read off outer
scale):
Note: a slight oscillation of the needle at 2500 to 3000 RPM (less than
two divisions) is acceptable.
Needle pressure should climb with RPM and remain steady (Fig. 3) =
GOOD READING.
