Usage:
Removal And Installation
1. Drain the coolant from the radiator.
1-Radiator inlet line (two). 2-Brace (two).
2. Remove the bolts (5) that secure the fan guard (3) to the fan shroud (4).
3-Fan guard. 4-Fan shroud. 5-Bolts (twenty-four). 6-Radiator outlet line. 7-Bolts (six).
3. Attach a suitable hoist and remove the bolts (7) that secure the radiator to the lower support bracket.
4. Lift the radiator slightly and swing it free of the fan.
5. Inspect all parts for wear or damage and replace if necessary.
REMOVING RADIATOR
Disassembly And Assembly
1-Guard.
1. Remove the radiator outlet elbow from the bottom tank (13).
2. Clean the radiator water cores of all accumulations of debris between the fins and tubes with water or compressed air. Such accumulations decrease the efficiency of the cooling system and may cause the engine to overheat.
2-Shroud. 3-Clamp, hose, and pipe (two). 4-Overflow tube. 5-Top tank. 6-Side assembly (two). 7, 8, 9, and 10-Cores. 11-Tank. 12-Post assembly. 13-Bottom tank.
3. The inside of the radiator cores, bottom tank, and top tank should be cleaned with commercial radiator cleaner according to the instructions furnished by the manufacturer.
4. Test the radiator for possible leaks before installing the radiator on the engine. This can be accomplished by plugging both the inlet and outlet openings and filling the radiator with water. Leave the water in the radiator for a long enough period of time to detect any seepage that might occur.
Pressure Valve Cap
A sealed pressure overflow assemby built in the radiator cap prevents loss of coolant through the radiator overflow tube when the engine is operating on an incline.
Due to expansion of the coolant by rising temperature, pressure will be built up in the system each time the engine is started. When the pressure rises to range of 4 to 6 PSI (0,28 to 0,42 kg/cm2) seal (1) is lifted off the filler neck (3) to relieve the pressure or, if the cooling system has been overfilled, to allow some coolant to escape through the overflow tube. The valve closes when the temperature of the coolant levels off and remains closed unless there is a further increase in pressure.
PRESSURE VALVE CAP (Earlier Type)
1-Seal. 2-Vacuum relief valve. 3-Filler neck.
When the temperature of the coolant falls, a vacuum will be built up in the cooling system. As soon as the pressure in the system becomes less than atmospheric pressure, the vacuum relief valve (2) opens and allows air to enter through the overflow tube. This vacuum relief valve also functions when draining the cooling system.
PRESSURE VALVE CAP (Later Type)
1-Seal. 2-Vacuum relief valve. 3-Filler neck.
