My temperature gauge won't rise and my coolant light, oil light,battery light airbag light, theft system light. and seatbelt light even if i put the belt on and the car is running won't go off. The oil level is fine i just put a water pump in and bled the system and the coolent level is fine the heater works great and it does'nt seem to be over heating. i don't know where to start looking for the solution

low operating temperatures is an indication of an air lock in the cooling system
gauges need the sender unit to be fully immersed in coolant to work but if they are not then the variable resistance material in the sender bulb cannot accurately relate to the coolant temperature
example if you have leak develop in a good system and you do not regularly scan your gauges like a good drive will do. it is possible that you will smell a dying engine yet when yo look at the gauge it will be reading cool to cold because the coolant has dropped to a point where the sender is no longer in contact with the coolant
If the check gauges light come on it refers to charging system, oil pressure, and engine temperature.So check the oil level,and you will need to know if the pressure is good. cooling system are you loosing coolant and is the radiator full, battery is the system getting charged. Now on the lighter side it can just be a faulty gauge
Are you describing something like this? This symbol indicates that your vehicle has detected a problem with the airbag or seatbelt restraint system. It won't (or shouldn't) interfere with the way your vehicle operates, but it will likely disable the restraint system to prevent improper inflation of airbags. Obviously, the system won't operate properly in an accident, so you should get this checked as soon as possible.
YOU NEED BLEED COOLANT SYSTEM.CHECK COOLANT LEVEL IN RADIATOR.ADD MORE DEXCOOL UNTIL COOLANT LEVEL IS CLOSE TO RADIATOR SPOUT.CRANK ENGINE LET IDLE UNTIL TOP RADIATOR HOSE GET HOT.WATCH TEMPERATURE GAUGE.IF TEMPERATURE GAUGE START RISING TO HOT ZONE.TURN OFF ENGINE.LET COOL DOWN.USE LARGE RAG SLOWLY OPEN RADIATOR CAP A LITTLE AT A TIME UNTIL ALL PRESSURE RELIEVED.REMOVE RADIATOR CAP.ADD MORE COOLANT.CRANK CAR AGAIN LET IDLE UNTIL TOP RADIATOR GET HOT.KEEP EYE ON TEMP.GAUGE ALSO.WHEN TEMP.GAUGE STOP CLIMBING.YOUR COOLANT SYSTEM BLED.WHEN DONE LET CAR SET A WHILE CHECK COOLANT LEVEL.ALSO FIRST THING IN THE MORNING CHECK COOLANT LEVEL AGAIN.AND BESURE ADD COOLANT IN THE OVERFLOW JUG TO THE COLD MARK.DONT OVER FILL THE COOLANT RESERVOIR JUG.WORK SAFELY DONT GET SCALDED.
When your temperature gauge reaches "H' it may too late to
prevent a major breakdown. Knowing the symptoms of an overheated car and how
they occur may be the difference between being inconvenienced and
incapacitated. Identification:---Other than a low oil level or low oil
pressure light, there is not a more significant part of a car's instrumentation
than a rising temperature gauge or a glowing "Hot" light. These
lights are really the only confirmation a driver has that his car is really
overheating. It is the identification of the symptoms of an overheating car
that enable the motorist to avert a badly damaged engine. Overheating is always
a traumatic event for a car's engine, which makes the early identification of
the symptom an important addition to the informed motorist's tool kit. Stuck Thermostat:--The car's thermostat is a valve that controls coolant
flow from the engine block to the radiator. When the engine is cold the
thermostat remains closed so that the coolant can reach operating temperature
quicker and also provide heat to the passenger's compartment. The thermostat
has a spring on it that moves depending on coolant temperature causing the
thermostat to open. Sometimes the thermostat fails to open thus restricting
coolant flow to the radiator where it would be cooled down. This condition is often
the cause of overheating. The symptoms of this cause would be a rising
temperature gauge and possibly the loss of heat inside the car. Restricted Radiator:---A car's radiator will have thousands of gallons of
coolant passing through in its lifetime. Along with the coolant comes
particulate matter in the form of corrosion breaking loose from various parts
of the car's cooling system. These contaminates collect in the tubes of the
radiator reducing its efficiency. Extensive "plugging" in the radiator
will cause the car to overheat. The symptom of this condition would be a rising
temperature gauge which goes up when you accelerate. Coolant Loss:--A car's
cooling system is a closed loop system. You are not supposed to lose coolant.
Sufficient coolant loss will cause the engine to run hot because engine is
heating less coolant to higher temperatures. The symptom of overheating induced
by coolant loss would be a pool of coolant on the pavement when the leak is
external. Steam under the hood as the lost coolant hits hot parts of the
engine, or a rising temperature gauge in the case of a undetectable engine
related leak. Of course, the gauge would also go up if the leaks were not
Deteriorated Water Pump:--Cars
use a belt driven pump to push the water and coolant mixture through the
cooling system. This part is called the water pump. Rarely the impeller that
draws the coolant through the pump will rust away making it impossible to push
any through the system. If this occurs the temperature gauge will climb and coolant
will boil over in the radiator.
cooling fans are electrically driven. Some are driven by fan belts. If a belt
breaks or the electric supply to the fan is interrupted overheating may result.
Electric fans are tuned on thermostatically when needed. When the car runs at
idle for extended periods or the weather is extremely hot, a failed fan will
cause overheating otherwise it serves as a standby assist to the rest of the
cooling system. In stress conditions an inoperable fan will cause the
temperature gauge to rise.
This will help. Thanks please keep updated.please please do rate the solution
positively .thank you for using fixya
If the coolant is below a certain level, the temperature sensor will not read anything and the temp gauge will not rise. Replace the cap, and check that you have enough coolant in the system. If this does not solve the problem, you will need to test/troubleshoot the coolant temperature sensor.
