Craig Posted May 17, 2022 Share Posted May 17, 2022 A somewhat basic question, but what antifreeze are you using in your Triumph? Quote Link to comment Share on other sites More sharing options...
Clive Posted May 17, 2022 Share Posted May 17, 2022 Blue ethylene glycol stuff. Both in my Triumph engine and my "updated" spitfire. I buy triple QX stuff from Eurocarparts as nice and local. 2 Quote Link to comment Share on other sites More sharing options...
yorkshire_spam Posted May 17, 2022 Share Posted May 17, 2022 Similar to @Clive a reasonable ethylene glycol depending on what's available when I need some. 1 Quote Link to comment Share on other sites More sharing options...

Tim Hunt Posted May 18, 2022 Share Posted May 18, 2022 +1 for Blue ethylene glycol type. I go for the concentrate, meeting BS6580-1992 and dilute 50/50 with filtered rainwater. I look for the best deal on ebay. I change the coolant without fail every two years and find that it drains readily out of the radiator and block as clean as a whistle. I carry some 50/50 nix on board in case top up is ever needed. 2 Quote Link to comment Share on other sites More sharing options...
Dave Clasper Posted May 18, 2022 Share Posted May 18, 2022 Blue, though only change every five years, still clean as a whistle and passes the test for "anti freezing". Quote Link to comment Share on other sites More sharing options...
