henry60 I own a 2014 Ford Focus Hatchback SE, whose mileage is 14,000 Kilometers now. I noticed the coolant was half an inch lower than the minimum level at the beginning of this month. I brought my car to a dealship. The dealship checked it and then told me nothing was wrong and they had topped up the coolant to the maximum level. A week later, the coolant already dropped to the minimum level. I think I have to take time to bring the car back to the dealship again. :-( I am quite unhappy with the experience of owning a Ford car. I think I won't buy another Ford car.

chemistkremer I've just looked at my coolant cap for the first time and I, too have brown crud in the cap. However, most cars I've owned have exhibited the same problem. My old Contour Zetec was especially bad, most of the reservoir was full of the stuff and try as I might, I could never eliminate it.

PratoN Coolant flush done! It's too bad that there's not really much that I can do about the brown crud coating the inside of my entire cooling system... I really only saw it in the degas bottle and the tube leading to it, but I'm willing to bet that it's everywhere.

wkumtrider Mine coolant is low as well. No issues so far, but I will check for leaks in places shown above.

Justintoxicated Mine was full of brown crud on the cap and in the reservoir, I just wiped it out but I think it will be back as soon as my warranty runs out.

As do I, but my projects seem to take longer than I expect.

I finally got my new rear bearings and upper control arms on the car - hopefully it will stop the heel-toe wear I was getting on my last 2 sets of tires (Why did I pay for an extended warranty...?)

Coolant flush is next on my list!

FocusStrider Hmm. I will have to check mine.. so far, at 85K miles.. no leaking problems, but I plan on doing the coolant flush and refill soon though.

While I think that's true (it's well-documented if you search dex-cool problems), the problem was why is there air in the "sealed" cooling system in the first place? The coolant level should not drop...

But I think the hose and the radiator posts above sum up the majority of the coolant issues on the MK3 Foci.

I believe DougC switched coolant types (non-OAT, green/yellow). I thought there were pictures somewhere, but I can't find them. If I recall correctly, it remained clean for the several months at which point he ended up selling his car anyway. There was also someone who bought a salvaged/repaired vehicle that used it. I don't think there will be issues (if well-flushed), OAT is just supposed to last longer.

Yeesh... yeah, your leak is much worse than mine was. I searched for hours around the radiator because that's where everyone else said their leak was, I guess I'm the exception this time.
