System Check

WARNING: Never remove theradiator capwhen theengine ishot; serious
burns couldbecaused byhigh pressure fluidescaping fromthe
radiator.
Wrap athick cloth around capandcarefUlly loosenita quarter
turn torelease built-uppressure. Thenremove thecap com-
pletely.

CHECKING COOLINGSYSTEMHOSES

Check hosesforimproper attachment, leaks,cracks, damage,
loose connections, chafinganddeterioration.

CHECKING RADIATORCAP

To check radiator cap,apply pressure tocap with atester.
Radiator caprelief pressure:
Standard
78 -98 kPa
(0.78 -0.98 bar,0.8-1.0 kg/cm
2,
11-14 psi)
Limit
59 -98 kPa
(0.59 -0.98 bar,0.6-1.0 kg/cm
2,
9-14 psi)

SLC613-A
Pullthenegative pressure valvetoopen it.Check thatitcloses
completely whenreleased.

CHECKING COOLINGSYSTEMFORLEAKS

To check forleakage, applypressure tothe cooling systemwith
a tester.
Testing pressure:
157 kPa (1.57 bar,1.6kg/cm
2,
23psi)
CAUTION: Higher thanthespecified pressure maycause radiator damage.
