Book Excerpt: Ford Tractor Repair Manual Models 2N, 8N, 9N
A pressure-type cooling system is used on 2N and 8N models, which means that more heat is required to make the coolant boil than if the system were not under pressure. The radiator is sealed with a cap that contains a pressure valve and a vacuum valve.
MAINTENANCE PROCEDURES: CRANKCASE VENTILATION
The pressure valve in the radiator cap maintains cooling system pressure at 3.5 to 4.5 psi (24-31 kPa), raising the boiling point of the coolant many degrees.
As the coolant heats, it expands, raising the pressure in the system. The vacuum valve in the cap admits displaced air when the engine is shut off, preventing damage to the system.
When the system is operating properly, the air in the upper tank expands and contracts protecting the system from damage.
The engine crankcase is vented to the atmosphere to remove water vapor, gasoline vapor and blowby products which can cause deterioration of the oil and the corrosion of engine components. The crankcase is vented through the oil filler tube breather cap (Fig. FO2).
If the crankcase ventilation system becomes restricted, the pressure in the crankcase will rise above normal. Higher than normal crankcase pressure may result in abnormal oil consumption and external oil leakage at the crankshaft seals.
The oil filler cap should be cleaned in suitable solvent after every 10 hours of operation.
To clean the fuel tank sediment bowl (Fig. FO5), turn fuel shut-off valve clockwise to closed position. Loosen sediment bowl retaining nut, move retaining wire clamp sideways and remove the bowl. Clean the bowl with a clean cloth. Remove and clean the screen located in the bowl cover.
