Review on πŸ§ͺ ACDelco GM RC107 Radiator Surge Tank Cap - Original Equipment, 16 PSI by Saradhi Suter

Revainrating 5 out of 5

OEM.OEM.OEM as standard

Stops a mysterious coolant leak on my 2011 DTS. The pressure was released via the cap O-ring and the coolant drained from the tanks while driving. If you slowly remove the cap after a long ride and don't hear any pressure relief, it's time for a new cap. This is actually an 18psi cap, not the 16psi cap as advertised.

Pros
  • Radiator Cap
Cons
  • Not bad
