You will have to get a better look could be a crack in the plastic end tanks to the rubber tank seals. Also hose's sometimes get a very small hole and only leak under the correct pressure or curtain flex.

Dry the area best you can get the car up to temp and pressurized and reinspect. Is it definitely coolant not atf?.

 

[commodore665]

Definitely coolant , my thoughts are similar to yours , it appears to hold pressure , but haven't really properly checked that
Cheers

Yeah bloody coolant leaks i would say get a coolant pressure test done but the test units come at a cost. Unless you know a mech/workshop that will do it for you without asking for $$.

Those Atf banjo line fittings can also slice in to radiator hose too. Once you had a good look get back to us just don't drive it too much and watch the temp gauge like a cop best of luck.

It's not overheating at all , and the gauge stays where it should , it's going to the workshop nextweek , and its a small leak but a leak all the same , plus I'm not driving it great distances ,
cheers again

Yes, mine leaked at the join from the plastic tank to the aluminium core, but it only did it when it was cold when first started, replaced radiator and problem fixed.

I went to 2 different radiator shops while travelling out west, and they both didn't have the adapter to suit the screw cap to pressure test the system.

I popped into Repco earlier just to see how much a pressure tester cost , holy **** they're expensive part of me thinks when I had the wheels painted , they also resprayed the front bumper , whether they took it off to do it I don't know , but something might have been knocked in the process

Crack in the plastic radiator tank, that’s where mine went and it only leaked intermittently

That seems to be the general view time will tell , it's going in on Monday as I've mentioned its a small leak , but small leaks often turn into bigger ones.
