Radiator Cap - Image 1](https://m.media-amazon.com/images/I/71LT439L2FL.jpg) ## Questions & Answers **Q: Where is this cap made?** A: always replace with factory part as much as you can **Q: Will this fit a 1992 silverado 5.7** A: As far as I know it was. My husband died back in March. I know he didn't send it back. **Q: Please advice what filler neck will suite to this cap - 43mm/56 mm/68mm?** A: 43mm **Q: will it fit 93 corvette** A: The picture looks nothing like the RC27. It's metal not plastic. Sorry can't help you with the 93 Vette. I used it on a 93 Cadillac Deville with a 4.9L V8. Not sure if it's to your application, but if yours is plastic - this isn't the one for you. - John ## Customer Reviews ### ⭐⭐⭐⭐⭐ Radiator cap *by G***I on 8 September 2025* It was a perfect solution to my problem with my old cap ! ### ⭐⭐⭐⭐⭐ Review *by C***S on 6 March 2026* Excellent quality.I definitely would buy this item again. ### ⭐⭐⭐⭐⭐ Review *by I***. on 7 April 2025* Schnelle Lieferung ## Frequently Bought Together - ACDelco GM Original Equipment RC27 15 P.S.I.
