Review on 🔧 Black Stant Engine Coolant Reservoir Cap: Enhance Performance and Reliability by Tim Thomason

This item was purchased to replace a 10 year old Toyota Rav4 OEM cap (Toyota P/N 16475-28140) that was leaking from the overflow hole on the reservoir. The Stant cap fits perfectly but the small locking tab at the top of the cap does not go into the tank to prevent it from coming loose like the original. I will be using the cap for a week before I get to the dealer and buy an OEM Denso cap and hopefully this stant will last that long. The materials on this cap are much softer than OEM Denso, but other than that it fits. If only there were small details and necessary attributes.
