(a) Tighten the drain plug.
(b) Plug the inlet and outlet pipes of the radiator with SST. SST 09230-01010
(c) Using a radiator cap tester, apply pressure to the radiator. Test pressure: 177 kPa (1.8 kgf/cm2, 26 psi)
(d) Inspect for leaks. HINT:
On radiators with resin tanks, there is a clearance between the tank and lock plate where a minute amount of air will remain, giving the appearance of an air leak when the radiator is submerged in water. Therefore, before performing the water leak test, first move radiator around in the water until all air bubbles disappear.
