If you have a small leak this product might be an easy and cheap fix. It did not work for me. Perhaps my leak was too large. It is hard to tell. **Q: Does it discolor the antifreeze? Thanks** A: Unfortunately I can't say. I have a GM vehicle that uses the orangish color engine coolant and it and this product are so close in color it's hard to say if it would discolor the usual green-colored coolant found in non-GM vehicles. The other challenge is that I can only look at the coolant through an overflow reservoir and it's so dark when I look inside (I have to use an LED flashlight to see it adequately) that it would be hard to tell if there was any discoloration. **Q: Can you use this in a 2013 escape?** A: You can use it anywhere. It's kept my 1998 Chevy Lumina going over 2 years with almost 178,000 miles on it! **Q: can you mix this with barstop if you all ready put that in the radiator?** A: I did mix this with Irontite All Weather Seal. Did the K-seal first. Irontite a week later. Just to be sure. Since they both said it can remain in the system. Two weeks, still good. ## Frequently Bought Together - K-Seal ST5501 Multi-Purpose One Step Permanent Coolant Leak Repair, 8oz, Pour and Go, Mixes with All Antifreeze, No Flushing Required - PEAK 50/50 Prediluted Antifreeze and Coolant for All Engine Cooling Systems - K-Seal ST3501 Pour and Go Head Gasket Sealer, 16oz, Permanent Repair for Blown Head Gaskets, Cracked Heads and Blocks --- ## 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.co/products/267704249-k-seal-st5501-multi-purpose-1-step-permanent-coolant-leak](https://www.desertcart.co/products/267704249-k-seal-st5501-multi-purpose-1-step-permanent-coolant-leak) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-09-26*
