2. Radiator (engine cooling) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(engine_cooling)

   A calibrated pressure-relief valve is usually incorporated in the radiator's fill cap. This pressure varies between models, but typically ranges from 4 to 30 psi (30 to 200 kPa). [4] As the coolant system pressure increases with a rise in temperature, it will reach the point where the pressure relief valve allows excess pressure to escape.

3. Inch of mercury - Wikipedia

   en.wikipedia.org/wiki/Inch_of_mercury

   Inches of mercury is also used in automotive cooling system vacuum test and fill tools. A technician will use this tool to remove air from modern automotive cooling systems, test the system's ability to hold vacuum, and subsequently refill using the vacuum as suction for the new coolant. Typical minimum vacuum values are between 22 and 27 inHg.

4. Leak-down tester - Wikipedia

   en.wikipedia.org/wiki/Leak-down_tester

   Compression tests should normally be done with all spark plugs removed to maximize cranking speed. Cranking compression is a dynamic test of the actual low-speed pumping action, where peak cylinder pressure is measured and stored. A compression tester. Leak-down testing is a static test. Leak-down tests cylinder leakage paths.

5. Internal combustion engine cooling - Wikipedia

   en.wikipedia.org/wiki/Internal_combustion_engine...

   The temperature of the cooling air may range from well below freezing to 50 °C. Further, while engines in long-haul boat or rail service may operate at a steady load, road vehicles often see widely varying and quickly varying load. Thus, the cooling system is designed to vary cooling so the engine is neither too hot nor too cold.

   Engine coolant temperature sensor; Hall effect sensor; Wheel speed sensor; Airbag sensors; Automatic transmission speed sensor; Brake fluid pressure sensor; Camshaft position sensor (CMP) Cylinder Head Temperature gauge; Engine crankcase pressure sensor; Exhaust gas temperature sensor; Fuel level sensor; Fuel pressure sensor; Knock sensor ...

7. Head gasket - Wikipedia

   en.wikipedia.org/wiki/Head_gasket

   Water-based coolant in the coolant passages; Lubricating oil in the oil galleries; Correct operation of the engine requires that each of these circuits do not leak or lose pressure at the junction of the engine block and the cylinder head. The head gasket is the seal that prevents these leaks and pressure losses.
