When jackaroo 1988 is motoring where does the needle in the temperature gauge normally be


If your temp gauge has only the cold (C) or hot (H) letters then the operating range would be the width of the needle under 1/2 way between c and h. If it remains steady at slightly over 1/2 way that would be just the setting of the gauge. How to get to know where the needle would sit at a specific position in relation to water temp. Do the following
Remove the temp sender unit and attach an earth wire to the body of the unit to earth. Place the sender unit in a container of water up to the threads .Put a mercury thermometer in the container beside the sender unit Apply heat to the container and watch the gauge needle move in relation to the thermometer reading. Operating temp will be about 80 degrees C on the thermometer and that would be about 1/2 way on the gauge.

No heat 99ford expendition ,it is like there is no hot water, temp gauge is reading normal range


when the car is at operating temp touch the heater hoses they should be the same temperature if not the heater core is plugged up and will have to be replaced.make sure the temperature door is working properly when going from cold to hot.if the door is not moving or not moving its full range it can cause this.

make sure that the coils, ( the ac radiator ) are clean , blow them out with an air hose if you can get a hold of one, also, make sure the ac fan is coming on, it may start , but the sensor may be bad allowing it to turn off too soon , a normal rise in heat is expected when using the AC but if it is too hot you should feel the motor start to run rough, if its running fine, and the temp does move back to normal when the ac is turned off, and a qualified mechanic has checked it, your probably ok, you could have a sensitive gauge, , If the normal range of the gauge moves to hot and back during normal driving without the ac on, that would show the thermostat is also working

Actually, if the temperature gauge is at the 25% vs. 50% that means the engine is running cool. That's good for the engine to run cooler rather than hotter.

However, there could be a restriction in the cooling system causing the heater not to get as hot as toast.

Good luck on flushing and repairing this anomaly in the cooling system.

Temperature gauge back and forth between normal


the fan comes on and off based on the "temperature sending unit" thats a thermal switch mounted on the radiator .. it is normal for the temperature to fluxuate as the fan turns on and off .. if it is allowed to get too hot before turning on then the temperature sending unit should be replaced ...while the car is moving the fan may never come on and isnt needed as long as air is flowing through the radiator .. as long as you are not loosing coolant then the temperatures are probably within proper range ... a sticking thermostat can also cause increased temperature range fluxuations .. that will show up as large swings of temp while driving .....

Check Engine Temperature warning


I disconnected the battery for about an hour to clear the car's computers and followed the Owner's Manual in the Maintenance section for the OBD II to allow the computers to relearn. This seems to have resolved the problem.
