Slow coolant leak

My TT is loosing coolant at slow rate . I tried to find the leak , but couldn't find any obvious evident . I really need help from Melbourne member , does anyone in Melbourne has Radiator Pressure Cooling System Leak Tester that I can come and try or hire ? Thanks in advance . Dinh

 

Have you checked the hoses or tried another hose? It could be the smallest hole that could be causing the leak. Try contacting Bryan at Brytech as im sure he will be able to help you. Might be a bit of a drive but would be worth it. Good luck.
