Except Villager

1. Turn heater controls to maximum and set air discharge to instrument panel vents. Turn blower to high. Fill cooling system with 50/50 mixture of coolant and water. Pause several minutes for circulation. Start engine and allow to idle. While engine is idling, feel for hot air at instrument panel vents. If air discharge remains cool and coolant temperature gauge does not move, coolant level is low.
2. Stop engine and allow it to cool. Top off coolant as necessary. Start engine and allow it to idle until normal operating temperature is reached. Hot air should discharge from instrument panel vents. Coolant temperature gauge should maintain a stable reading in middle of range. Upper radiator hose should feel hot to touch. Stop engine and allow it to cool. Top off coolant as necessary. Check for coolant leaks.

Villager

1. Remove engine air relief plug. (Scheme 1) Fill cooling system with 50/50 mixture of coolant and water to radiator filler neck. Gently move upper radiator hose up and down while filling to remove trapped air. Insert a.079" (2 mm) wire under negative pressure valve of radiator cap. (Scheme 2) Install radiator cap. Disconnect expansion tank tube from radiator. Hang a modified one gallon bottle filled with 50/50 mixture of coolant and water. (Scheme 3) Connect and clamp a hose from modified bottle to expansion tank tube connection at radiator.
2. Unclamp modified bottle hose. Allow coolant to flow until coolant comes out of engine air relief plug. Clamp modified bottle hose. Install engine air relief plug. Raise front of vehicle about 22" (55.8 cm) and support with stands. Turn heater controls to maximum and set air discharge to instrument panel vents. Turn blower to high. Unclamp modified bottle hose.
3. Start engine. Set engine speed to 1500 RPM until cooling fan turns on. Turn engine off and allow to completely cool off. Clamp modified bottle hose. Remove modified one gallon bottle and reconnect expansion tank tube to radiator. Remove radiator cap and remove wire. Fill cooling system with 50/50 mixture of coolant and water to radiator filler neck. Fill expansion tank to MAX mark. Install radiator cap.

BELT ADJUSTMENT

Inspect belt for fraying. If fraying has occurred, ensure belt and tensioner are aligned properly. (Scheme 4) If tensioner has reached its limit of travel, belt is excessively stretched and replacement of belt is required. (Scheme 5)- (Scheme 11). If excessive noise is noticed from tensioner or idler, check for possible bearing failure. Belt tension adjustment is not required on vehicles with automatic belt tensioners. DO NOT apply belt dressing or any other additive to belt(s). Ensure belts are properly installed. (Scheme 25)- (Scheme 21). See BELT TENSION ADJUSTMENT SPECIFICATIONS table.
