Remove Cap and Check O-Ring

If you want to know if your cap needs replacing, remove the old cap and check the O-ring. If the o-ring is flush with the stem in the cap, you will need to replace it. When I compared the old and new baseball caps, the alignment in the new baseball cap is well rounded and billowy. This is of great importance to maintain the correct pressure in the system.

Pros
  • Automotive
Cons
  • Almost OK
