Alright, got a long 20inch strip of thick paper and shoved it in the coolant reservoir,
this is what came out
it probably scraped on the bottom of the container
there is no liquid in there...
that gunk is a dark green-gray gunk ... buggers
i also bought a jug of Prestone dex-cool 50-50 from Autozone (i asked for "the orange one" as the Chrysler mechanic told me over the phone)
is it ok to pour it in the reservoir, or would it push the crud down some pipes?
