What causes the coolant temperature gauge to be in the red zone and the check engine light is not on?

The engine is overheating. The check engine light is not on because you have no problem with the emissions system which this light monitors.

What causes the 'Check gauges' light to come on in a Ford Explorer?
* Check gage Illuminates when the engine coolant temperature is high, the engine oilpressure is low or the fuel gauge is at or near empty.
How can you check the Engine Coolant Temperature sensor on my 91 Honda Prelude SI 2.1L?
How can I check the ENGINE COOLANT TEMPERATURE (ECT) sensor on my 1991 HONDA PRELUDE SI 2.1L
Why does check gauges light come on and temperature go up?
That happens because the engine is overheating. Normal causes are low coolant, bad thermostat, or inoperative fan.
Your 1996 Nissan maxima is overheating occasionally what should you do?
Overheating is due to, well, the coolant in the cooling system getting too hot. In a normally operating engine, this should never be a problem. First, check that the coolant level is correct. If it is correct, I would suspect a problem with the thermostat. When the engine is cold, the thermostat closes off coolant flow through the engine until the coolant reaches a pre-determined temperature. When that temperature is reached, the thermostat opens to allow the coolant to circulate at that exact temperature. Thermostats are known for failing and either not opening or not opening enough at that pre-determined temperature. This causes coolant to get trapped too long in the engine coolant chambers, heating it beyond limits, causing the engine temperature to increase and possibly overheat. If my Maxima was overheating, I would check the coolant levels and then possibly replace the thermostat. It usually is no more complicated than that.
What is P3081 mean in the check engine computer?
Engine too cold. Possible causes: thermostat failure, air pocket within coolant system, malfunctioning temperature sensor. Normal operating temperature should be 202 degrees Fahrenheit.
Can coolant temperature cause your check engine light to come on?
Yes, on some vehicles it can.
What causes Coolant indicator light to come on when you first start your car?
Check to coolant level in the coolant recovery tank and radiator when engine is cold
What happens if engine coolant is put in while the car is off?
After coolant is added run vehicle to normal operating temperature and re-check coolant level
Why does the temperature gauge fluctuate in cold weather and heat comes on and off?
Check coolant level Could be thermostat opening and closing due to engine coolant temperature flutuation
What does check engine code p0128 mean on 2002 Isuzu rodeo and how much will it cost to fix?
it is low coolant temperature, could be the thermostat could be the sensor for coolant temperature.
Where is the location of the check engine light on a 97 Ford Explorer?
On a 1997 Ford Explorer : CHECK ENGINE is just to the left of the " C " on the engine coolant temperature gauge ( Helpfull )
Why does your 2001 caravan put out heat spurratically?
Check to verify the coolant level is full. If the vehicle has a engine coolant temperature guage, does it reach and maintain a normal temperature duing vehicle operation? If not have a mechanic check for a leaking head gasket.
