Antifreeze
Antifreeze
Can any one advise me what type of Antifreeze I should be using in my tiger that is fitted with a aluminium radiator. Should I be using red or green/blue?
it doesn't really matter. i use the modern red organic acid technology (OAT) stuff because its not such a nasty chemical as ethylene glycol or propylene glycol .
its more expensive and they say not to mix it with the glycol (yellow/green) stuff so you'd need to do a full flush of the block with water if you switched.
i actually end up changing it at least once a year for one reason or another, but if you don't, the green/yellow stuff should be changed every 2 years.

Hi,
Distilled water is better, less corosive. As for water wetter, I tried it and all I got was a header tank full of sludge, and had to flush the whole system. If you don't want your rad to block, it's best to flush out once a year any way. allso an engine runs cooler with no anti freeze, but not good for corosion.

i use brita filtered water because i can never find distilled water. brita removes about 60-70% of the total dissolved solids. water is a better heat sink than antifreeze so i use about 30% antifreeze and the rest water. i also find gano filters particularly useful on old cars. i have one in my tiger (but there is never so much as a speck of debris in it!)
Antifreeze Update
Having researched the web I have found this link - http://cc.derekharris.com/Antifreeze%20 ... 9%20V8.pdf
It seems Fernox Alphi II that is used in central heating systems is recommended for classic cars. I have decided to try this with purified water.
Many thanks for all your posts.
