Useless Product, 7 Aug. 2015
My 99 Subaru Legacy Outback 2.5 ltr had a leaking head gasket.
I used 4 bottles of Steel Seal as instructed over two treatments and drainings.
This product did not cure the problem and it was necessary to remove the engine and strip it to skim the heads.
The Block and accessories were cleaned of Steel Seal as best as possible.
The Steel Seal contaminated the radiator, necessitating a new radiator and even after radiator replacement and numerous back flushings, the Steel Seal residue continued to cause blockages in the heater matrix and caused additional overheating.
As a professional marine engineer of 40 years , Chief Engineer for 24 years I do not consider this product to be suitable for any engine.
What was supposed to be a suitable fix ended up as a nightmare .
I had to call RAC out twice.
I would not endorse this product under any circumstances.
