Checking Cooling System For Coolant Leaks

WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

To check for leakage, apply pressure to the cooling system with a tester.

  1. Testing pressure : 157 kPa (1.6 kg/cm 2  , 23 psi) 
WARNING: Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure coolant escaping from the radiator.
CAUTION: Higher pressure than specified may cause radiator damage.
