It is normal for the temperature to increase a little when a vehicle comes to stop this is due to the no air being forced through the vents or grille in front as the car moves forward however the temperature should increase to a set ever then you will hear the electric fan come in automatically that is if the vehicle is fitted with an electric fan

    Thank you for your reply, but I'd like to ask is it normal to be rised to the half or more, and something more happening the coolant water for the reda. is boilling and fall down on the ground?!

  • Mohammed Aug 08, 2012

    one more note, the weather in my country is very hot, and the air condation is on

  • no this is not normal the pressure is obviously getting too high in the water system, is read from you original note that it only does this when the car comes to a stop, if so can you check if this vehicle is fitted with an electric fan

  • the aircon system works with its own radiator/coil which you will notice put up against the radiator for the vehicle, if you are noticing this only when the vehicle comes to a stand still i could be either the mechanical thermostat has failed or the electric fan is not working or if not equipped with an electric fan then the mechanical/viscous fan is damaged

2001 Cadillac DeVille RPMs revving dying

battery not charging , means the charging system is not working , Doesn't mean the battery is bad . The charging system on your vehicle is computer controlled , If the BCM doesn't see the correct voltage , it will raise the idle RPM to over come any load on the system . Probably has DTC'S - diagnostic trouble codes stored in the BCM or PCM , These codes do not always turn on the money light ( check engine ) . Your best bet , take it to the Cadillac dealer , auto zone or any of those has no clue about this . Oh also it will shut down systems .
Battery symbo - Charging System Indicators

BATTERY NOT CHARGING - 7Charging System Indicators

The IPC illuminates the BATTERY NOT CHARGING - 7 indicator in the DIC when the PCM detects a malfunction with the generator output. The IPC receives a class 2 message from the PCM requesting illumination.

I work for Cadillac , have for over thirty year's . Have seen people mess this stuff up big time . So do yourself an take to one of my fellow tech's.

Electrical Load Management
The power management function is designed to monitor the vehicle electrical load and determine when the battery is potentially in a high discharge condition. This is accomplished by using a high accuracy battery voltage reading as an indicator of battery discharge rate. The following six levels of load management will execute in the load management control algorithm when there is a high discharge condition:
The first action requests a vehicle idle speed increase to the powertrain control module (PCM) in order to raise alternator output.
The second action requests a greater vehicle idle speed increase to the PCM in order to raise alternator output.
The third action begins to shed vehicle loads in an attempt to remedy the heavy discharge condition.
The fourth action requests another vehicle idle speed increase to the PCM in order to raise further the alternator output.
The fifth action begins to shed further vehicle loads in an attempt to remedy the heavy discharge condition.
If the above five corrective actions fail, the sixth action of power management further sheds loads in a final attempt to remedy the high discharge condition.
Loads subject to reduction include the following:
• The A/C clutch
• The heated mirrors
• The heated seats
• The rear defog
• The HVAC blowers
The power mode master (PMM) calculates the battery temperature, voltage and charging rate at all times while the engine is running. The PMM calculates the battery temperature by factoring in:

No heat on my mitsu montero sport 2001

either you have an air lock in the heater core or is leaking. first off pull the carpet around the floor and see if its wet or damp, also look for water marks to indicate water leakage, if the floor is wet then you have a leak.If its an air lock you need to raise the front of the vehicle so that the radiator cap is the highest point in the car, jacking it up usually works.start the car and turn the heater on to hot, warm the car up to normal operating temp then just fill the radiator and the air bubbles should come out.If you do this and you see a heap of small bubbles continually coming up really fast, then you have either a cracked head or a blown head gasket

Soon as i turn on my heat my cooling fans come on first

It sounds like you do need a thermostat with your heat shut off and the gauge will raise a little then the car doesn't have that heat drawn from it indicating that you most likely do need a thermostat. As far as the fans coming on immediatly that could be a different problem it is most likely the coolant temperature sensor that tells the fan's when to come on. If this sensor says the coolant is hot the fans will come on immediatly. These are seperate problems as the coolant temperature sensor does not have anything to do with the cabin heating system. You should first check the level of your coolant is full, This could also cause your cabin heating system to perform poorly, and may have adverse effects to the engine cooling system. (fans)
