EXPECTED READINGS AND THEIR DEFINITIONS
Check at idle speed (less than 1000 rpm)
Read the reading at idle on the inner scale.
Result: Needle continuous in the blue zone.
GOOD READING
With the engine running at idle expect to see no significant rise in
pressure needle should be steady.
Check at idle speed (less than 1000 rpm)
Result: Quickly climbing or oscillating pressure.
BAD READING
Gas present in cooling system, possible cylinder head gasket failure.
Check at a speed of 2500 to 3000 rpm.
Reading taken from outer scale.
Note: a slight oscillation of the needle at 2500 to 3000 RPM
(less than two divisions) is acceptable.
GOOD READING
Needle pressure should climb with RPM and remain steady.
Check at a speed of 2500 to 3000 rpm.
Reading taken from outer scale.
Test result: no rise in pressure.
BAD READING
No increasing of pressure indicate that impeller is broken or seized.
Check at a speed of 2500 to 3000 rpm.
Reading taken from outer scale.
Test result: Needle oscillating more than two divisions.
BAD READING
A needle that oscillating more than two divisions indicates that the
drive belt slippage or the impeller or shaft damage.
REMARK
This product cannot detect leaks in the cooling system, damaged seals, collapsed hoses or
blockages. If no gas is detected and the pump shows a normal reading then any overheating may be
due to a faulty thermostat, fuel mixture, leaks, collapsed hoses, defective pressure cap or a blockage
in the cooling system.
