we have used irontite on a race motor to get us thru. 12.5 :1 compression ratio and it still held in, much to my surprise.

I used irontite for about 9 months in a rover 216 until I sold the car (yes I told the new owner). Motor was spitting water and running on 3 cyls. Drained the antifreeze and followed the instructions and it was perfect as - sealed up no problem. The only concern was couldn't use antifreeze with irontite (sends it like gooey jelly) but in Auckland thats not a problem. I also left the irontite in the system. After draining while hot a couple of times and leaving hoses off to let the waterways air dry I put the irontite back in and had no problems. Air dryingputs a coating of the silicate on the waterway channels and protects from corrosion (was a bit worried about the alloy block)

The cooling system has to be pretty clean to have success with Irontite, on a system that isn't, Sealwell cubes are a better option.

I have used irontite with good results but huge amounts of time and cost with flush and 4 drain and refils to get the system clean enough. I second the suggestion of sealwell have used it for 11 years and always had a good ending to the story.

is sealwell compatible with coolant! are there any products you can simply add to the cooling system without draining it first!

Antifreeze or at least a corrosion inhibitor is still needed in Auckland.

What I meant was surely some form of corrosion protection is required even if there is no risk of freezing. We had our first frost of the season this morning down here. (North Otago)

I have never dropped the coolant out of the system when using sealwell. and if anything I have topped up the system afterwards with coolant.
