You need to install a new thermostat. The stat is located at the lower end of the top radiator hose within the water outlet. After the stat is installed, run the car with the radiator cap off for about 20 minutes checking and adding coolant as the air is pushed out of the system. Keep a eye on the coolant level over the next few weeks to insure the system does not have a leak which could be why you had this problem in the first place.
the temperature in 1991 accura integra is fluctuating dramaticlly from normal to very hot to normal...why ?
An XM radio is no more difficult to install than a normal car stereo.
3 answers spring to mind, an air lock in the water system,a faulty switch on the heater panel( or cable depending on year)or an inline vent flap stuck shut
No, it's not normal. You have a leak in the heater core or may just be connections to heater core. If left untreated, it will soak into your rug and eventually cause your floor to rot.

If the engine is getting up to normal temp, the heater core might be plugged. Heater core is not plugged and normal operating temp!
Provided the heater is of a low wattage it should not affect normal running of the car
you have no heat and car runs normal
Usually much smaller. A normal freeze plug block heater is about fifty bucks.
No, they should be underneath.
simply put you can't if it is idleing not normal their is a problem surging/hunting idle=fuel pump/filter high idle =vacuum leak or sometimes fuel pump
Only by jury rigging it ... the normal insulation is designed to vent the heat outside. But it can be used as a form of electric heater.
