No it sounds more likely to be a heater core a little clogged.try back flush ing it.

SOURCE: WILL NOT SWITCH AIR FLOW STUCK IN DEFORST VENT

when your car is in defrost it has an ac cycling it removes the moisture then sends the air over the heater core depending on how warm you set it you can feel warm or cold but the ac is always cycling...ridding the moisture...you need a good ac tech it will be okay...its just expensive going into the heater core if needed...!

SOURCE: 1990 honda accord temp gauge above hot limit.

Hi there,

Firstly - DO NOT run engine, when guage reads hot, as this will cause costly damage to head gasket & alloy engine head.

The fact that guage takes 1min to read HOT, would confirm the guage IS working properly.

So, other components which are likely to cause hot readings (in this order) are:

- lack of coolant (or leakage somewhere): is there sufficient green coolant at the correct level? Top up mixture to correct level. Repair any leaks.

- collapsed radiator hose: when engine is cold, start engine, then quickly watch both upper & lower radiator hoses to see if either begins to flex inwards (collapse). Replace if either hose is collapsed.

- bad/incorrect thermostat rating : when replacing thermostats, you must ensure it is of the SAME temp rating (they all differ).

- Incorrect Temp sensor rating: the ratings of this sensor must be within manufacturer's spec's.

- bad waterpump: the engine relies on the waterpump to distribute the coolant throughout the entire system. If waterpump is faulty, coolant will not flow quick enough, causing overheating.

If you still believe all of the above components are OK, then have your cooling system "pressure tested". This test should be done, before looking further at other electrical components.

Cheers,

"if this has helped you in any way, please rate this solution"

My A/C ONLY WORKS IF THE COOLANT TEMP GAUGE WORKS IVE CHANGED THE COOLANT TEMP SENSOR AND LOW PRESSURE SENSOR WHAT CAN I DO NEXT


have you had the coolant itself checked , may not have enough in system , this could stop the gauge registering as only reads hot water/coolant not hot air/steam

My 1996 honda accord doesnt heat up like it suppose to..unless its juss parked without any movement.. I drive it 2 miles away and it still doesnt heat up im concerned !! Any help ????


Thermostat stuck open?
Faulty temp sensor or gauge?
If heat comes out of the heater, engine thermostat is ok. That will isolate it to probably the temp sensor in the temp indication system (sensor & gauge).
The cooling system should be full. Temp sensors cannot read the engine temperature of steam or empty cooling galleries.

2004 santa se 2.4L Temp gauge reads normal, but heat from vents excesivlly hot.will not start after running for a while until it sits 1/2 hr.


There is a blower control resistor (manual system) or a blower transistor (automatic temp system) located behind the glove compartment in the HVAC box and this is a high failure item.

Check the connectors at the PCM or ECU; lose ones could cause this problem. Something else to consider is to get the sensor from the dealership; many of these sensors are very sensitive and aftermarket ones tend to not be calibrated correctly.

Does the air coming out of the vents change when you move the temperature control knob? If you can't feel it, you should be able to hear the change

Temp. gauge reads high some times. but the motor really isnt hot


It sounds like the coolant temperature sensor is beginning to fail. It is highly unlikely that the in-dash gauge is a problem. The coolant temp sensor inputs to the computer affecting everything from radiator fan speed, engine fuel/air calibration and a variety of other parameters.

Be absolutely certain to "burp" every bubble of atmosphere from the coolant system too. Air bubbles have the amazing ability to prevent coolant flow and will cause all sorts of problems, especially if the bubble wants to hang around the temperature sensor location.

Normal operating temperature is going to be around 210 F.

Most Autozone, Advance locations will read engine problem codes at no charge, so drop by one of those locations and let them read the problem code.

My guess will be the coolant temperature sensor. Then have the problem code reset, remove all air from the coolant and let us know how this worked.

1995 ford windstar overheat after replacing the thermostat


Let your engine warm up with the rad. cap off and see if the coolant level drops. and make sure your overflow is full. It blows cold air because there is no water getting to the heater core. And it shows a normal(ish) temp because the water needs to be touching the temp. sensor. I really do think there is air in the system and there is not enough coolant but hard to tell from here. Also as with overheating any time make sure to check your oil and look for any coolant as the head gasket seldomly holds together if the motor overheats.
