Job failure when it was done 7 months ago?

Maraming maraming salamat.

"Slow leak" . . . this would be difficult to find.

Tap water and mineral water is bad.

Yan ang difference ng water terms sa radiators.

Job was done 7mos ago, driver noticed only last month. Sino last-touch, yung Motech o casa?

Si Motech yung last touch Sir. Check ko ulit yung sticker, may date sila na nilagay dun kung kelan sila nag service. Will update here

follow this advice Salanguit
top up lang ng top up.
pag bago ka maka 1 liter (mine was about 500ml), titigil din yan "leak" na yan.
took almost a week IIRC

Actually sir dinrain ko existing ko, pero sa radiator at coolant reservoir lang. Nagtataka lang ako nung binuhos ko orange coolant tapos distilled water, naging green siya sa ibabaw.
Anyone here experience the same?

Is it necessary to do a coolant flush?
How would we know if there are build up already so flushing is needed?
Is radiator cleaning the same as flushing the coolant?

Thanks in advance guys.

As for my experience, I’m always doing the coolant flush. To clean properly the radiator.
