I figure if it works for Subaru, it should work for other car.** A: This is just a Subaru labeled version of Holt's Radweld @ holtsauto.com, so check their website for more info. I did some research, and yes, Subaru specifies it for the 2.5L engine, due to a common gasket failure, perhaps to get thru the warranty period before it fails. It is made in England, and contains borax and linseed meal. I used it in my 1992 Firebird, and added two bottles because it has a larger coolant capacity.Holt's claims to contains rust inhibitor, and the sealant particles are not likely to clog your radiator or heater core, so it can be used as a preventative to seal minor leaks, should they occur. I think it is better than other products on the market. The current price here is high, so I would try to find an equivalent product at your local auto parts store. **Q: Can i use this in a 2013 wrx 2.5 turbo or is only for non-turbos?** A: I was just at a Subaru dealership and was going to buy this along with Subaru coolant for my 2006 WRX 2.5l Turbo, and the parts counter guy double checked with a tech in the back who said he stopped using this with turbo cars, so I didn't buy it. I also don't have any leaks or anything along those lines. I think they used to use this every coolant change as part of it but not anymore on the Turbo models. ## Frequently Bought Together - Subaru Coolant System Conditioner - SOA635071 - Genuine OEM - Subaru Genuine Super Coolant Blue Prediluted SOA868V9272 1 Gallon Pre Mixed 50/50 2009 and Newer Ascent BRZ Crosstrek Forester Impreza Legacy Outback WRX - EPAuto Spill Proof Radiator Coolant Filling Funnel Kit --- ## 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.tw/products/2504567-subaru-coolant-system-conditioner-soa635071-genuine-oem](https://www.desertcart.tw/products/2504567-subaru-coolant-system-conditioner-soa635071-genuine-oem) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-08*
