If his expansion cap is going from max to min each time then that volume of fluid should be turning up somewhere if it's leaking? Don't forget it'll likely only be leaking under pressure (engine running) the turbo will be very hot if it's weeping on a run and if it's leaking round the turbo area it will dry off very quickly leaving just crystallisation. I've seen it many a time on engines no visible wetness just a lot of crystallisation Quote Link to comment Share on other sites More sharing options...
Gordmac Posted December 31, 2020 Share Posted December 31, 2020 If there was much of a leak the system wouldn't really hold pressure. Lower pressure would mean a lower boiling temperature and your leak may be steam rather than water, should be traces of antifreeze where it leaks from though. Other thought is if a significant leak then would it not draw air in the leak rather than fluid in from the tank? Quote Link to comment Share on other sites More sharing options...
JonC Posted December 31, 2020 Share Posted December 31, 2020 I think the only way to know for sure is to strip the whole thing down and rebuild it. GPSguru 1 Quote Link to comment Share on other sites More sharing options...

suzook12 Posted December 31, 2020 Share Posted December 31, 2020 You got one of them odd Japanese ones, similar to my Nissan terrano, no cap at all on that..... Sounds like you are displacing air from the system bud after the turbo and cooler were done..... Quote Link to comment Share on other sites More sharing options...

Would be better if you could find any bleed points, but would certainly give it another 2 or 3 trips out. If you can access any disturbed joints in the system, even if with a mirror and torch, just to make sure. Sometimes running for a little while with the cap off can help shift air, but you need to make sure the cap is the highest point in the system. If it doesn't settle, then you may need to get a tester to put on to try and find any issues. I certainly wouldn't panic jest yet tho....

Saintly Fish Posted January 2, 2021 Author Share Posted January 2, 2021 So I checked the level of the coolant in the bottle before we set off today and it was on max, just where I left it after the last trip. I checked it again after our trip and it was still on max. So, looks like any air has been expelled. But, I did find a small leak, nothing major and seeing as the boats getting lifted Tuesday I’m not worried for now.

JonC Posted January 2, 2021 Share Posted January 2, 2021 My low water level alarm went off today, I was about a litre down. I confess to not checking last couple of trips out though. My engine isn’t very clean so not so easy to spot residue as yours. Quote Link to comment Share on other sites More sharing options...

This is a good example of what it looks like, this one is pink as that is the colour of the coolant mix Saintly Fish 1 Quote Link to comment Share on other sites More sharing options...
