It says to idle for 20 minutes** A: The system should be sealed as the product circulates though it for the 20 minutes. **Q: Does it use Sodium Silicate?** A: Nowhere on the bottle does it say sodium silicate. **Q: I have a 1999 ford ranger. running fine now but it is getting older. can i use this as a preventative? or do i need to wait for a problem to show up?** A: The way K seal works is by seeking out leaks in a pressurized system. I feel you or best bet would be to wait until you know your leaking coolant. I use this in a truck about 7 months ago and I still have no problems with the truck. Work very well **Q: can i make a 100 make a 100 mile trip 10 minuets after i put the k-seal in...** A: Yes! It does it's magic within 10 minutes. Just don't drive it too hard for about 20 minutes. Drive smooth. Highway driving or a good road with a consistent speed is best. After 20 minutes, you are all good! ## Frequently Bought Together - K-Seal ST3501 Pour and Go Head Gasket Sealer, 16oz, Permanent Repair for Blown Head Gaskets, Cracked Heads and Blocks - K-Seal ST5501 Multi-Purpose One Step Permanent Coolant Leak Repair, 8oz, Pour and Go, Mixes with All Antifreeze, No Flushing Required - K-Seal ST5516 Heavy-Duty Multi-Purpose One Step Permanent Coolant Leak Repair, 16 oz, Pour and Go, Mixes with All Antifreeze, No Flushing Required --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/82132425-st3501-pour-and-go-head-gasket-sealer-16-oz-repairs](https://www.desertcart.gr/products/82132425-st3501-pour-and-go-head-gasket-sealer-16-oz-repairs) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-07-15*
