chances are you have a oil leak, (valve covers or oil pressure sensor or oil pan) and your lim bolts are seeping coolant, just like mine have been for 6000 plus miles.

i have 2 bolt valleys that have coolant in them, and one at the end that coolant runs off the side but steams off before you would know it was there.

i also have the old plastic gaskets and should change them on general principals but i am letting it go for now.

i'd address the oil leak first.
