Test Cooling System
CAUTION: Explosive release of fluids from
pressurized cooling system can cause
serious burns.
Shut off engine. Only remove filler cap when
cool enough to touch with bare hands. To relieve
pressure before completely removing, slowly
remove pressure cap and allow pressure to
relieve before completely removing cap.
Test Radiator Cap
1. Remove radiator cap and attach to D05104ST Tester,
or similar, as shown.
2. Pressurize cap to following specifications.
1
. Gauge
should hold pressure for 10 seconds within the normal
range if cap is acceptable.
Specification
Radiator Cap—Maximum
Pressure........................................................ 124 kPa (1.24 bar) (18 psi)
If gauge does not hold pressure, replace radiator cap.
3. Remove the cap from gauge, turn it 180°, and retest
cap. This verifies that the first measurement was
accurate.
Test Cooling System for Leaks
NOTE: Engine should be warmed up to test overall
cooling system for leaks.
1. Allow engine to cool, then carefully remove radiator
cap.
2. Fill radiator with coolant to the normal operating level.
IMPORTANT: DO NOT apply excessive pressure
to cooling system; doing so may damage
radiator and hoses.
3. Connect gauge and adapter to radiator filler neck,
or expansion tank. Pressurize cooling system to the
following specifications
1
.
Specification
Cooling System—Maxi-
mum Pressure............................................... 124 kPa (1.24 bar) (18 psi)
4. With pressure applied, check all cooling system hose
connections, radiator, and overall engine for leaks.
If leakage is detected, correct as necessary and
pressure test system again.
If no leakage is detected, but the gauge indicated a
drop in pressure, coolant may be leaking internally
within the system or at the block-to-head gasket. Have
your servicing dealer or distributor correct this problem
immediately.

Test pressures recommended are for all Deere OEM cooling systems.
On specific vehicle applications, test cooling system and pressure cap
according to the recommended pressure for that vehicle.
