Coolant Leak Repair K-Seal 236mL - Supercheap Auto Australia

Ok ok ok.... before anyone else think (WTF).... I've tried this, and it worked. Many moons ago I had an E90 BMW, it suffered head gasket failure, being too stingy (then), I couldn't be bothered fixing it (as fixing a BMW is not cheap to say the least), so I googled crap and came out with this. It's a bag of mixed reviews, but because it's an old car, I didn't really gave a crap and tried it out. Surprise, surprise, this worked! never drop another coolant ever again. Gave it to a mate with a 2000 Explorer, it worked too.

From my experience, it definitely worked for me. Best $20.00 spent in my life (back then). But do Google because it's a mixed bag of reaction on this. For me, as I said earlier, it worked miraculously....

Good luck, but as people above said, being a Subaru dealership, you wouldn't think they would not do anything for you more chance then when you buy it from a backyard dealership.
