Plug the inlet and outlet pipes of the radiator with SST. SST 09230-01010
Using a radiator cap tester, apply pressure to the radiator. Test pressure: 177 kPa (1.8 kgf/cm2, 26 psi) Submerge the radiator in water.
(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 doing the water leak test, swish the radiator around in the water first until all air bubbles disappear.
