Yeah. Or take the current one and put it in boiling water to make sure it's functioning properly. They're cheap, but why replace if it's not necessary?
I always boil new ones too, after buying a couple that were bunk.

Hello car experts and enthusiasts, I've done some research via online forums, but thought I'd take my issue straight to my favorite hangout (ATS).
Vehicle: 2005 Honda Civic LX (Automatic)
Issue: Heater blows cold/tepid air at idle and below about 25 MPH, otherwise works great. Sometimes when I am below 25 MPH it will suddenly begin to work- I've noticed this just after going over a speed-bump. After driving for some time (30 minutes or more) the heating system USUALLY works as it should, but will still randomly exhibit the problem at stop-lights, or at idle after briefly shutting engine off.
Other notes: Had some minor work done a few weeks ago to replace a leaking rear cam seal, never noticed issue with heater until AFTER this service was done. The repair shop also "topped off" coolant.
My suspicions: Vacuum leak or air in cooling system-- or, maybe airflow valve (in firewall) sticking???
My request: Any advice for what I can do to further pin-point the problem, ways to resolve the issue myself, or what I should expect to pay to get it fixed. I don't mind doing some basic repair/replacement work, but if it requires specialized equipment or tools I will have to rely on a mechanic/shop.

I would replace the thermostat...probably the easiest and cheapest fix to try.
It could be as simple as that.
Usually around $10 for that and a gasket depending on which kind you have.
