1994 Honda Civic car wont stop overheating

Hi, you need a temp gun - they're gettin' real cheap and are handy for t-stat operation check (or replace it ), fan operation check, (what does "not sure if it comes on. Mean), radiator flow, and it's good for parties, too?). You also need a "block check" kit (follow instructions that come with it) for combustion gases in cooling system. Maybe a Honda guy will pipe up but it seems I've heard of head gasket problems being common with age/mileage you have. Oh, I guess it's called a "non-contact thermometer with laser sighting" - get one with at least two laser dots.
