Foam in radiator coolant

**madduck** · November 7th, 2013 11:51 AM

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.

Did you replace the head gasket recently? What you're seeing (foam) is minute oil contamination already. Its a head job, conservatively speaking.

Try a leakdown test. See here: ** How To - Leakdown Test ** - Honda-Tech

Sorry to scare you. Your situation is very subjective, maybe its bound to happen and just coincided with your synthetic oil switch. To tell you honestly, I've seen perfectly running engines (with mineral oil inside them) become a leaking, smoke belching mess because their owners decided to use synthetics.

Bring your car to a reputable mechanic for diagnosis. And then get a second opinion from a different mechanic. From there, you can minimize the guesswork.

actually, foam in radiator coolant means head gasket failure.

^^ all good sir, i appreciate your help.

anyway, anyone familiar with a shop that can do head gasket replacement? It's not a simple job, right?
I checked with my usual shot and quoted me, 4.5k for the labor. is that fair? suggestions are welcome. thanks.
