Help!! I am smelling a coolant on my 90 Civic EF sedan like if it were leaking but I can not find were it is leaking. It seems to be coming from were the intake manifold is but when I check my hoses they all seem to be fine... When I get under my car I notice that there are water marks all over my cat converter.... Any advise on what i should check???? Also my name is Josh i'm new to the group
