Now at 155k I havent had any problems (or headgasket leaks as the dealer informed me). The Radiator is old and cracking now so I would replace that all together this time along with water pump. **Q: Do I use both bottles or just 1** A: Some Subaru models are notorious for head gasket issues. Subaru developed this additive with Holts to prevent problems from faulty head gaskets. Use one of these every time you do you your 30,000 miles coolant flush. If adding it before your next flush, just remove 4oz from your radiator (when cool). It is a brown goupy solution with chunks, you must shake VERY well before pouring. Some owners swear by this stuff, some are mad they have to use it in the first place, and some put it in and forget it. Recently has seen widespread use in non-Subaru makes because of it's excellent performance compared to other Stop Leak products. If your car is showing signs of head gasket issues, it is advised to try this out, and then use it with every coolant flush. Other head gasket failure preventions: - Make sure your battery terminals are corrosion free **Q: Can I use this in turbocharged engine?** A: Most places online say it wasn't meant for turbo models. That doesn't necessarily mean it won't work if you have a coolant leak. It's a rebranded product made a British Company called Holts. The Holts product name is Radweld. Subaru rebranded it for use in a recall of 99-2002 ej25 models with weak head gasket material. Those are not turbo model engines, but the turbo models weren't recalled for it, if that helps. If you have a coolant leak, it's worth a try. It's cheaper than replacing a head gasket. **Q: Can this cooling system conditioner be used in vehicles other than subarus? or is it designed to be used only in subaru vehicles?** A: any vehicle ## Frequently Bought Together - Subaru OEM Coolant System Conditioner - SOA635071-2 Pack - Subaru Genuine Super Coolant Blue Prediluted SOA868V9272 1 Gallon Pre Mixed 50/50 2009 and Newer Ascent BRZ Crosstrek Forester Impreza Legacy Outback WRX --- ## 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.be/products/16110185-coolant-system-conditioner-2-pack-soa635071-genuine-oem](https://www.desertcart.be/products/16110185-coolant-system-conditioner-2-pack-soa635071-genuine-oem) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-04*
