Nissan Micra Water Pump Removal & Radiator Pressure Test - Cooling System LC-6

This page is from a Nissan factory-style service manual section titled "ENGINE COOLING SYSTEM" (page LC-6), covering the water pump and radiator. The left column details water pump removal and installation precautions: avoid getting water on the timing belt, check for excessive end play and rough operation, replace the pump as a unit (it cannot be disassembled), apply sealant to bolts because bolt holes are drilled through water jackets in the cylinder block, and run the engine after installation to check for leaks. An exploded illustration shows the water pump assembly behind the timing belt, with a bolt torque specification of 4-5 N·m (0.4-0.5 kg-m, 2.9-3.6 ft-lb) and sealant applied to the mating surface. The right column covers radiator inspection: checking cooling system hoses for leaks, cracks, damage, loose connections, chafing and deterioration; pressure-testing the radiator cap with tool EG17650301 (relief pressure 88 kPa / 0.9 kg/cm² / 13 psi); and pressure-testing the cooling system for leaks at 157 kPa (1.6 kg/cm², 23 psi), with a caution that exceeding this pressure may damage the radiator.
