INSPECTION OF ISC VALVE
1. CHECK RESISTANCE OF ISC VALVE
Using an ohmmeter, measure the resistance between terminals B₁ — S₁ or S₃ and B₂ — S₂ or S₄.
Resistance: B₁ — S₁ or S₃ 10 — 30 Ω
B₂ — S₂ or S₄ 10 — 30 Ω
2. INSPECT OPERATION OF ISC VALVE
(a) Apply battery voltage to terminals B₁ and B₂ and while repeatedly grounding S₃ — S₂ — S₃ — S₄ — S₁ in sequence, check that the valve moves toward the closed position.
(b) Apply battery voltage to terminals B₁ and B₂ and while repeatedly grounding S₄ — S₁ — S₂ — S₁ — S₄ in sequence, check that the valve moves toward the open position.
INSTALLATION OF ISC VALVE
1. INSTALL ISC VALVE BODY AND TWO BOLTS
2. CONNECT FOLLOWING HOSES TO ISC VALVE BODY:
(a) Two air hoses
(b) Two water by-pass hoses
3. CONNECT TWO ISC VALVE CONNECTORS
4. FILL WITH COOLANT
