[Yota]

hi there, for first.. im from ger. sorry for my mistakes

my engine or what ever steams after 20 minute rides (if engine is fully warmed up)
i have no idea where the steam comes from.. i looked in my coolant bottle and noticed some milkshake-foam..crap! what could it be? mayb the head gasket?? but there is no foam in te oil.

Do a compression test and then flush your coolant. You may just have excessive scale built up.

Sometimes coolant systems will "foam" or bubble because there is air in the system. Usually the steam is just from the overflow tube. I would start by draining the system. Then getting some new coolant and filling the system. Then idle the car watching the coolant lvl. You'll have to add more as the air filters out. But after sometime the coolant will get the air out. And hopefully you'll be golden.

You radiator could have a very small leak, and will only steam after the engine is fully warmed up, happened to me.

I agree with everyone above but I had this same thing happen to me and it took months to chase the bug down.


I know some of you guys may think this is way far off but I had the same problem a few years back so please dont jump on me with the BS card as its from PERSONAL experience, I know its uncommon but it was actually the oil cooler that had failed and was exhibiting the same milky-coolant symptoms you are, uncommon yes, happened to me though.
