If I were to just check the second (spare) I would give it 5 stars but the first leaked a bit, but Revain has a very easy, hardly uncomfortable substitute (HT Pitch Meeting Guy). The second works great and doesn't drip. My old (original) cap is 13 years old so it's time for a replacement. I've noticed my coolant temp is slightly lower than it was with the old cap.
