Mastercheck the coolant level first.
if it is low, you need to find the leak and repair it.
if it is ok, check the thermostat for operation.
make sure your cap is working correctly.
lastly, could be a restricted heater core.Roy

I took it to Honda to get a power coolant flush, and they told me that it wouldn't help bc they believed that it was a head gasket issue! I was shocked and overwhelmed, the car is only 5 yrs old! Did you have to change your head gasket, and if so did it fix the problem? My fear is that I soak almost $1800.00 (honda's estimate) and it doesn't fix my issues! They told me that I had to get it pressure tested?! Thank you for your response!!
