theredkite Posted June 14, 2014 Share Posted June 14, 2014 Hi, having got the engine to run with some fuel in the carb, I want to top up the coolant before I go any further. I've had a look on this forum and on the wider web, (and in the manual), but I can't see if there's any particular coolant I should use? Many thanks again, Mike Quote Link to comment Share on other sites More sharing options...
MatchFuzee Posted June 14, 2014 Share Posted June 14, 2014 You could try the Jaguar forums. Morris Lubricants products are all very good:- http://www.morrislubricants.co.uk/scripts/prodList.asp?idCategory=190 Quote Link to comment Share on other sites More sharing options...
timbo Posted June 15, 2014 Share Posted June 15, 2014 I just use the blue stuff in approx a 50/50 mix.... Quote Link to comment Share on other sites More sharing options...
martinwcox Posted June 15, 2014 Share Posted June 15, 2014 Ditto on what timbo said except over here its green. I would seriously consider draining and filling and bleeding the system or at least get one of the cheap hydrometers that check the coolant quality and freeze point. Over here where we get pretty cold in the winter, its a must. Unless you have the decks off the easiest way is to pull the radiator hoses off on one end. Remember that in the raised position the radiator is isolated by the trunnion valves and needs to be in the normal position to drain, fill, bleed. Its great to see you asking all the questions before you bugger it up and there is a wealth of help available here. We all had to and contiune to learn, sometimes the hard way I might add! Cheers, Martin. Quote Link to comment Share on other sites More sharing options...
theredkite Posted June 17, 2014 Author Share Posted June 17, 2014 Cheers for the help, I went blue in the end. I won't be changing the coolant now as my priority is to get the beast moved, but it will be a priority when I have the time to give her some proper tlc. Incidentally when I was cruising the web for tips the Army Rumour Service website had a chat about coolant - apparently in service (much higher usage than most of us I guess) failing to change the coolant regularly was a major cause of J60 failures.

andym Posted June 17, 2014 Share Posted June 17, 2014 Blue should be OK but note that the colour isn't always an absolute guide as there isn't a standard as such. The important thing is to ensure that it doesn't contain any OATs. Andy Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 17, 2014 Share Posted June 17, 2014 OK, what does OATS stand for. Unless your implying chuck Army Porridge in to plug leacks? Actually I was shown many moons ago how to fix a Gipsy radatior temporarily with a couple of duck eggs. Quote Link to comment Share on other sites More sharing options...
andym Posted June 18, 2014 Share Posted June 18, 2014 Organic Acid Technology, which is usually (but not always) red in colour. This tends to eat seals and yellow metal in older engines that aren't designed to use it. Andy Quote Link to comment Share on other sites More sharing options...
Tony B Posted June 18, 2014 Share Posted June 18, 2014 Thanks , I always stick to blue. Quote Link to comment Share on other sites More sharing options...
