Review on 🔧 ACDelco GM Original Equipment 10-2010 RTV Engine Sealant - 5.3 oz Cartridge for Superior Engine Performance by Steve Hauck

The product arrived and the expiry month was erased on the tube. It expired in 2019 after 31 days in the month. When my mechanic tried to pull it out of the pipe it didn't leak. I noticed in the ad that the product was past its expiration date, but I was expecting a fresh product when I bought it. Don't waste your money - if it doesn't work after applying, you'll have to pay for a rework. Since my job required partial disassembly of the engine and was quite expensive, the mechanic and I decided to toss it and use something newer. Next time I'll buy from the dealer.
