WARNING: This page is about a different car, the 2006 Honda Odyssey and 2005 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the radiator cap (A), wet its seal with engine coolant, then install it on a commercially available pressure tester (B).
- Apply a pressure of 93-123 kPa (0.95-1.25 kgf/cm2 , 13-18 psi).
- Check for a drop in pressure.
- If the pressure drops, replace the cap.
