4C-6500 Digital Thermometer The 4C-6500 Digital Thermometer is used in the diagnosis of problems that cause overheating or overcooling in the engine. This tool can be used to check the temperature in several areas of the cooling system. The testing procedure is in Tool Operating Manual, NEHS0554.
Illustration 3 g00313263
8T-2700 Blowby/Air Flow Indicator The 8T-2700 Blowby/Air Flow Indicator is used to check the air flow through the radiator core. The operating instructions are included with the tooling.

9U-7400 Multitach Tool Group The 9U-7400 Multitach Tool Group is used to measure the fan rpm. The testing procedure is in Tool Operating Manual, NEHS0605. Adding The Antifreeze
Do not add pure antifreeze to the cooling system in order to adjust the concentration of antifreeze. The pure antifreeze increases the concentration of antifreeze in the cooling system. The increased concentration increases the concentration of dissolved solids and undissolved chemical inhibitors in the cooling system. Add an antifreeze and water mixture in the concentration which provides the desired freeze protection. Use the following chart in order to determine the correct concentration of antifreeze in water to use.
Table 2
Antifreeze Concentrations For Freeze Protection    
Temperature     Concentration    
-15°C (5°F)     30% antifreeze and 70% water    
-23°C (-9°F)     40% antifreeze and 60% water    
-37°C (-35°F)     50% antifreeze and 50% water    
-51°C (-60°F)     60% antifreeze and 40% water    Testing The Pressure Cap
One cause for a pressure loss in the cooling system can be a faulty seal on the radiator pressure cap.

Pressure cap that is mounted on the radiator (4) Sealing surface between the pressure cap and the radiatorUse the following procedures to inspect the pressure cap and test the pressure cap.
Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.
When the engine has cooled, loosen the pressure cap to the first stop. Remove the pressure cap when the pressure is released from the cooling system.
Inspect the pressure cap carefully. Look for damage to the seal. Look for damage to the surface that seals. Remove any debris on the cap, the seal, or the sealing surface.
Put the pressure cap on the 9S-8140 Pressurizing Pump .
Observe the exact pressure when the pressure cap opens.
Compare the pressure to the pressure rating that is found on the top of the pressure cap. The pressure cap is faulty if the pressure cap opens at a pressure beyond the range that is found on the pressure cap. Replace a faulty pressure cap with a new part.Testing The Radiator And Cooling System For
