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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ SCSC *by A***R on 1 March 2026* Works very good highly recommended ### ⭐⭐⭐⭐⭐ Was surprised this actually worked *by R***S on 26 September 2024* I had a slight leak from the bottom radiator hose and thought I'd give this a go as a non-invasive fix.
