Question 1

Do I only put in 1 bottle per fluid change/flush?

Accepted Answer

Only 1 bottle is required per fluid change...

Question 2

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

Accepted Answer

You can use 2, but it is meant to stop seapage and not stop leaks

Question 3

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.

Accepted Answer

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.

Question 4

Can i use this in a 2013 wrx 2.5 turbo or is only for non-turbos?

Accepted Answer

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.
