Check your radiator's water level with the engine not running, also check the reservior level. If they are low top off the radiator until it is full with antifreeze and the reservior to the full line on the outside of the reservior. For the check engine light make use of Autozone's free engine light check, they can tell you what the codes are and the best solutions to fix the issue(s).

What does code P 119 mean on my Cadillac 1994 Seville STS


P0119 Cadillac Engine Coolant Temperature Circuit Intermittent
Possible causes - Low engine coolant level
- Faulty Engine Coolant Temperature (ECT) sensor
- Faulty engine coolant thermostat
- Engine Coolant Temperature (ECT) sensor harness is open or shorted
- Engine Coolant Temperature (ECT) sensor electrical circuit poor connection What about the obd code? The Engine Control Module (ECM) detected an erratic signal from the engine Coolant Temperature (ECT) sensor during the system monitor test Symptoms - Engine Light ON (or Service Engine Soon Warning Light) P0119 Cadillac Description The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.

High coolant temp


It is possible, how ever, I would check for inop coolant fan, or restricted radiator. If parts of the radiator are cool to the touch when the coolant fan has kicked in, very possibly resricted flow of coolant through the radiator.

'low coolant light' flashes all the time and then 'service engine soon'


These problems may or may not be related. The Check coolant light means that the coolant level in your radiator is low. If you have checked it and it is not low, then the sensor is most likely defective. The low coolant sensor will not turn the Check Engine light on - even if the coolant really is low. There are many things that can cause the Check Engine light to come on. You will have to scan your Engine Computer to find out why it has been turning the light on.

I did have a problem on one of these cars one time where the Check Engine light was coming on and there were several codes for the Throttle Position Sensor(TPS) and the Manifold Absolute Pressure (MAP) sensor and the car ran really bad. The Check Coolant light was also on. After checking it out I found that the coolant level sensor was shorting out the 5 volt reference circuit (VREF) from the computer and causing the whole problem. Replacing the coolant level sensor fixed the car.

My wife reports a check engine light and a red square with a wavy line warning light...can you help


The red square with the wavy light is a low coolant warning light. The check engine light could be on for many reasons. I would check the coolant and add some if it's low. Then you can take your car to many different places to have the engine code read. Most AutoZones and Advanced Autos and other auto parts places will have a customer use code reader and will pull the code for you for free. I would address the coolant problem asap, low coolant can cause your engine to overheat and blow the engine. The engine light may also just be on because you have the low coolant warning. If that IS the reason for the engine light, after cycling (car gets to normal operating temp then completely cold) the car about 3-5 times the light will go off on it's own. Good Luck!

bad low coolant switch or still low on coolant.

Engine Cooling The cooling system components are the:
  • engine coolant temperature sensor (ECT sensor) (12A648)
  • radiator (8005)
  • degas bottle (8A080)
  • radiator draincock (8115)
  • water pump (8501)
  • water temperature indicator sender unit (10884)
  • water thermostat (8575)
  • dual speed fan motor assembly
The water pump circulates the coolant.
The water thermostat:
  • controls the engine coolant temperature.
  • allows quicker engine warm-up.
The degas bottle:
  • provides a location for fill.
  • contains coolant expansion and system pressurization.
  • provides air separation during operation.
  • replenishes the engine coolant to the system.
The fan motor (8C607):
  • operates only when the ignition switch is in the RUN position.
  • will not operate with the switch in the OFF position.
The engine coolant flows:
  • from the lower radiator hose (8286) to the water pump.
  • from the water pump to the engine block and the cylinder heads.
A closed water thermostat returns the engine coolant to the water pump; an open water thermostat allows the engine coolant to flow to the radiator.
Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle.
When adding engine coolant, use a 50/50 mixture of clean, drinkable water and engine coolant.
To maintain the integrity of the coolant and the cooling system:
