best antifreeze for 1.6 diesel? temp gauge 3/4?

[kingdalg]

hello, hello! im going to change my antifreeze on my 82' 1.6 diesel devon pretty soon, just wondering can you use any or do you have to use the anti corrosion stuff they put in the waterboxers? any info appriciated, cheers

Im sure you are ok with "normal" coldmaster blue in a diesel (thats what I used) ...

The special stuff from vw is for the wasserboxer engines ...

cheers m8, what about the pink stuff?

[matt brighton]

Pink lasts longer - 5 yrs

Blue should be changed every 2 years - I use comma super coldmaster in my 1.6 na 1982 diesel

Pink recommended for later / alloy engines

Hope this helps

Regards

Any organo/acid anti corrosion inhibitor based antifreeze (pink/orange/purple) all have a more stable and so longer lasting base typically 5 year protection.
Darker green/blue antifreezes are based on older formulas and will need changing much sooner 2-3 years.
35 - 40% mix should be fine.
Both are fine but shouldn't be mixed so if you are changing from one type to the other, be sure the whole system is properly flushed through (which should be done anyway to rinse out the slightly acidic remains from the old contaminated mix).
Organo/Acid inhibitor based A/Freezers cost more but offer superior protection over a longer time frame.
