Foamy Antifreeze - 94 SL2

Can anyone tell me why my antifreeze woudl have the consistency of a fresh
cappucino in the resevoir?
It's been this way for quite some time - never seems to be much of a
problem, just that every 6 months or so my low coolant light flashes at me.
I top her off an dI'm good to go.
Foamy antifreeze seems wrong though, so any suggestions woudl be great.

My 97 does that, and maybe twice a year it throws up onto the pavement a
couple of cups of coolant a few minutes after I've shut it down.

I assume it's those pellets causing the color and foam.

 

dont know about the newer vehicles but in older cars when teh antifreeze
foamed it was due to cavitation in the water pump.. and that was caused by
either too hot condition(overheat) or low antifreeze condition.

 

Hey there, does ure coolant look like the normal green color ? Or is it ornage
? If it is not one of those colors and it kinda looks like chocolate milk than
I suggest you check your oil, if you have been going through oil latley than
you may have a cracked head. A friend of mine had one that did that and they
took it to the dealer and thats what they said it was. If it overflows than
there is a problem since it shouldnt overflow since it is a closed system
unless the car is overheating.
