Why would the temperature gauge fluctuate randomly either cooler or getting hotter after having the thermostat replaced?

Some cars have ground wires connected on the Thermostat housing bolts & the wires break. SOME aftermarket Thermostats (EL CHEEPO'S) are total JUNK.NAME Brands are best 2 go with.HOPEFULLY (IT) is installed correctly-SOME U have a 50/50 chance -The thremo Bulb goes away from the radiator .

92 Astro van dies without warning you have replaced the ignition coil and the cgr valve Had the fuel pump checked and it has good pressure you are at a loss?
Check the temperature sender. not the sensor, the sender. the sender goes from the thermostat to the computer. They have been know to prevent vehicles from running. I second that.

The typical signs for a blown head gasket is white exhaust coming from the tailpipe, gradual coolant loss, rough idle, temp gauge may fluctuate a bit while driving.
If your 93 Chevy is still overheating after you have replaced the thermostat what should you check next?
Has the rad ever been flushed? Try that if there is no indication of water pump failure (leaking or venting coolant from pump.)
If you already replaced the radiator fan but it is not switching on does that mean the thermostat is the next place to look?
if your thermostat was bad your engine will over heat but it has nothing to do with the fan,fans are driven by a diffrent mechanism. try checking your thermostatic switch/ heat sensitive switch or sensor, located somewhere in the cooling system(radiator,engine block or thermostat housing) which is the one that tells the fan when to come on.(only electric fans)it may be faulty wiring

Check into the temperature control valve--this is different than the thermostat.

Thermostat probably needs to be replaced.
Why does my car surge and won't start replaced thermostat and radiator?
When the thermostat and radiator were replaced, coolant could have dripped into an electrical connector or a sensor could be disconnected or damaged. Check the temperature sensor and crankshaft sensors first.
How do you know when you have bad thermostat?
If your engine takes a much longer time for the thermostat heat guage to reach its required level of operatiing temperature then the thermostat may be stuck in the open position which means that it will need to be replaced.
2000 Ford Escort ZX2 temperature gauge gets no reading Replaced temperature sensor radiator full of coolant Any Ideas?
Be careful there is a temperature coolant switch mounted next to the thermostat housing. I thought this was the sensor and replaced it by mistake. There is another sensor.
How know if you need to change your thermostat on a 1993 Honda Accord?
If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing. As the water pump should be replaced at the same time as the cam belt every 90,000 miles, you should also replace the thermostat and coolant.If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing.

There is an engine temperature sensor that operates the cooling fan.

The thermostat is done it has to be replaced.......
How can you tell which component is badthermastat or relay switch for a 1992 ford escort lx?
The thermostat or the fan relay for the radiator fan. If the temperature gauge shows the engine to be hot the fan should be on. If the fan isn't on you can check it by removing the electrical connection to the temperature sensor. If the fan is all right it will come on by default when the wiring connector is removed. Usually it is the thermostat which needs to be replaced when the engine is overheating. If the top hose going to the radiator isn't hot when the temperature gauge shows the engine to be hot the thermostat is stuck shut and should be replaced.
