Hi guys, need your help. Below are my observations.


1. Foam in the radiator coolant. (Brownish/white)
2. Loosing coolant.
3. Engine oil is clean, not milky.
4. No overheat, yet.


I've searched and read that the foam in radiator coolant is a sign of head gasket problem if the engine oil is milky too. My engine oil looks fine, and I didn't noticed any loss of engine oil. I've just changed oil 2 weeks ago, previously mineral to full synth, now I'm seeing this foaming in the radiator coolant. After seeing it the first time, I drained the radiator and reserve and refilled with distilled water. After several days, may foaming ulit. Head gasket issue pa din ba kapag ganyan? Salamat.
