## Questions & Answers

**Q: Do I only put in 1 bottle per fluid change/flush?**
A: Only 1 bottle is required per fluid change...

**Q: I was wondering if i can use 2 containers instead of 1? i have a a 04 forester and it has a small leak. i used 1 already but did not seal**
A: You can use 2, but it is meant to stop seapage and not stop leaks

**Q: Can I add this to my 2000 GMC Jimmy radiator for the same purpose? 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.

Este producto es altamente necesario para cualquier subaru no importa el año, es necesario cuando tiene mucho kilometraje y quieres darle una ayuda extra, el tamaño es muy pequeño porque es lo que el manual de servicio indica para que no se asusten
