Ok, good. You *don't* have the later 'brown tank' system....as shown in one of your earlier posts.

You have the earlier 'metal tank' system....which has the header tank on the engine.



I suspect you have a very small head gasket leak. I'd take a 'wait and see' approach at this point. Keep monitoring it and wait for developments.....which may occur tomorrow, or year after next, or......?

Ok thanks...Jerry

 

You could try one of the coolant sealant type additives. Some folk swear by them, others hate them. A very minor leak may be "cured".

 

Good idea I wil give it a try. Thanks Jerry

 

As a footnote I reran the leak test it turned out ok, I think on the first test run the radiator was too full and some of the antifreeze might have gotten into the container and contaminated the solution. Thanks jerry

 

Not sure what solution the antifreeze contaminated???


Yeah, some of the crystalline sealers work, at least for a while. Jaguar
factory solution not so good. Seals wanted passages as well as the unwanted....


Against his usual advice son used one on his ancient Case tractor. It worked, Probable source, the seals at the base of it's wet cylinder liners. Neat old beast...

The solution used in preforming the leak test(hydrocarbon leak test on cooling system) on the radiator. Thanks Jerry
