Car Forum / Acura Cars / December 2004ATTN: ACURA GOD - where's the heat
My car usually has super hot heat, but all that has changed. I'm guessing there's an eletric coil that heats up and the air blows over it before exiting the vents. I was wondering what the techincal name for this part is, how much it is and how much it's going to cost me. Thanks in advance for your help.

Sometimes this can be caused by a colling system thermostat that is stuck open. Does your car have a temperature gauge? If so, is the needle on that gauge below the "normal" range? mikey >My car usually has super hot heat, but all that has changed. I'm >guessing there's an eletric coil that heats up and the air blows over [quoted text clipped - 4 lines] >Leif >urgeintheicebox@NOSPAMgmail.com Cars normally get heat from the coolant used to cool the engine. There is a mini radiator inside the car called the heater core. The hot engine coolant flows through the core and air is blown over it and into the cabin. If you aren't getting heat a likely cause would be a stuck thermostat, which would prevent the engine from warming up properly. This should show up as a low engine temperature. Other possibilites could be that the heater flap no longer opens when the heater knob is turned (broken cable) or that your fan no longer works. Good luck Are your seat warmers turned on? Maybe that's why you are so hot. > My car usually has super hot heat, but all that has changed.

Your problem has several causes, depending on above factors.  SignatureTeGGeR? The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ >> My car usually has super hot heat, but all that has changed.

Probably a failed or failing thermostat. I haven't heard of any Acura with only electric heat,I imagine that only high-end Acuras would have electric "quick-heat" assist.

It was -20C here this morning. -- I put 2 and 2 together and got 22. >>> My car usually has super hot heat, but all that has changed.

Total absence of heat can also be due to problems with the interior climate controls. A failing thermostat often manifests as increasingly *poor* heat. And for the OP, interior heat is derived from the engine's cooling system. You have a tiny radiator inside the passenger compartment. A fan blows over the "rad" and sends it, via various tubes and blend doors to where you tell it to go by the dashboard knobs and switches. The water flow is usually turned on and off via a valve set into one of the heater hoses. If the blend doors (or knobs and switches) are not operating correctly, or if the heater control valve is stuck and not opening, you will get no heat. One quick check is to warm the car up fully, turn the heater on, and then under-hood, feel both heater hoses where they go into the firewall. If one is noticeably cooler than the other, the heater control valve is not moving to the "on" position. SignatureTeGGeR? The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ If your coolant is mostly water, and freezes, the engine will get really really hot, and you will have no heat inside the car. Don't ask. -- I put 2 and 2 together and got 22. I am surprised that nobody as suggested that the no heat condition can be due to the low level of the cooling fluid.
