SOURCE: 97 f 150 runs hot for minutes then runs ok

It could be a faulty thermostat. Did it do the same thing before u replaced the t-stat? It sounds like it's sticking closed, then all of a sudden it opens, coolant flows correctly. I'd consider changing it again. Check to make sure parts store is giving u the correct temperature thermostat also. Maybe it's too high for your Ford, delaying the opening.

SOURCE: 2004 Bonneville - Temperature Gauge is Erratic

Since there is no voltage applied with the ignition off, if the gauge is not dropping down all the way, it is the gauge that has failed.
Temperature sensors are frequent failures but they are not active when the car isn't powered up. They can be intermittant, high, low but with no power, the gauge itself should go to the minimum.

SOURCE: COBALT TEMP GAUGE READS 250 DEGREES BUT ENGINE

Probably the temp gauge itself. Most of the time it doesn't have a problem but sometimes they do go bad. Did the car ever overheat prior to changing the solenoid?

Keep getting fault codes 12 & 23 on 93 Olds Bravada already replaced Manifold Pressure Sensor and Intake Air Temp Sensor


The code 12 usually just means the system is in diagnostic mode. The code 23 should be for the mat system, not map.

Mat is manifold air temp.
Are there any driveability issues? Does the vehicle start and run ok?

My dodge caravan dashboard cooling gage is giving false reading.how do I repair.


How do you know its wrong? What have you done to establish that opinion? Gauges are pretty reliable, you need to check the sensor on the engine, usually on the thermostat housing. They are cheap and easy to replace by someone with a little experience. Don't do it with a hot engine. If you have an old style mercury thermometer, check the water temp when warmed up against what the gauge says. Thats warm up not full running temp. 10 mins or so of idle or until the gauge starts to move.

Vibration at idle


it may be idle control sensor or a bad mas air flow sensor--maf sensor in otherwords. or could be engine misfire at cold temp. start. only time when cold? or does run better when warm? try warming engine to operating temperature before driving,if problem removes it's self after warm up,up grade gas to 93 octane for 1 tank full. then see if problem goes away. it's cold where you are right? if so the fuel needs to be at least midgrade 89 octane fuel because 87 octane fuel will not start your honda correctly at cold temps. in cold weather 93 or super gas octane will start ,no problem,low octane fuel sometimes gels, or freezes at low temps. if in warm climate, change the fuel filter, add fuel injector cleaner to your fuel tank[preferablly lucas fuel treatment] this will lube your fuel injectors and give better fuel mileage. thank you for choosing fixya.com

Heater output not warm


First check to see if the system has the proper amount of coolant in it. Sounds like the heater core is blocked. You must get circulation in order to get heat. I assume the electric fan/blower is working.

My 93 jeep wrangler 4 cylinder temp gauge doesnt work right. when driving the gauge reads 0 when i step on the gas the gauge moves to the right temp. i have installed a new therm. new water pump new...


depending on how fast, this happens, could be an air lock in cooling syste, or a bad head gasket, or head. does the gauge ever go too high? can you hear gurgling in the rad, and does it ever push out coolant?

94 bravada temp.gauge not working on dash could it be temp.sensor


It could be the sensor or the wire harness it self where it connect's the the sensor. There is just one lead wire and it may be damaged due to corrosion or a broken wire. Check the wire first before replacing the sensor, remember the Bravada is 15 years old. Good luck friend and keep me posted, be glad to know you got your Olds running 100% again.

I have a 91 bravada all gauges work but my temp can some help


Find and check the temperature gauge sensor 'sender' unit on the engine.
To test:-
- if you ground the wire connected to the sender the gauge should go to full scale high,
- open circuit the gauge should read zero (nil deflection).
If above test ok, replace the temperature sender unit with correctly specified item.
