When your thermostat is not working properly or is stuck closed this will not allow the coolant to properly circulate through the engine which may cause the engine temperature to fluctuate erratically or in some cases just remain hot. You may be able to free it by pushing the center back and forth till there is no longer any resitance but it needs to be replaced.

Engine temperature gauge goes up and down. However if the thermostat fails to open your engine will heat up quickly but without coolant liquid it could overheat more quickly. Thats why you should always keep an eye on your temperature gauge and avoid high repair bills. Some thermostat faults might cause the temperature to climb and drop in mere moments.
The primary reason your car temperature gauge goes up and down while driving is simply because a component in your cooling system is not functioning correctly. This could be the thermostat valve radiator hoses radiator fan the temperature gauge or the coolant itself that circulates around cools off the engine. When your thermostat is not working properly or is stuck closed this will not allow the coolant to properly circulate through the engine which may cause the engine temperature to fluctuate erratically or in some cases just remain hot.
When the thermostat is stuck open it can cause the coolant to circulate constantly resulting in the motor never reaching the correct. Gasket has been replaced at that time but after 600 hundred km without any issue i am facing this constant problem of the temperature gauge going crazy and for whatever reason it comes from 90 steady up to 120 in about 30 to 40 seconds and then it comes back down while im still driving and then all the cycle again up and down up and down sometimes more than 120. My temperature gauge keeps going up and down when.
Pull off the hose at the top of the motor if you can see the thermostat try pushing on the center with a screwdriver it is most likely stuck open. You may be able to free it by pushing the center back and forth till there is no longer any resitance but it needs to be replaced. Engine temp gauge goes up and down.
Rui Peters Its starting to get serious. 0 in 0 posts. Hy everybody My little van has a suspected head gasket temp gauge goes up and down while driving but never boils over.
Im no mechanic i did a head gasket test and its showing negative so any sugestion and help. The main reason why car temperature gauge goes up and down while driving is because something is not working properly in your cars cooling system. It could be the radiator fan water pump thermostat valve coolant or the gauge itself.
To fix either of these issues wed advise that you engage a proven auto mechanic. It happens even more so when the heater is ON which it would be -20. When the coolant goes through the heater core it gets cooled off enough that when it returns the thermostat closes again momentairly.
So the temperature goes up and the thermostat opens again and then it goes back down. Your car temperature gauge goes up from 100 to 200 degrees F in 3 to 5 minutes after your car engine starts running that is normal because your car thermostat is close. My temp gauge was well under 210 driving down the highway then all of a sudden it jumps up past 210 between 210 and 260.
I pulled over and felt around the engine and it wasnt even hot. Then I got back into my truck and a few seconds later the temp gauge jumped back behind 210 and stayed there. My temp gauge almost reaches the max the car is running good once i continue to drive the gauge goes down to 34 then back to 12 then it goes up the coolant is full the heater is working fine.
I have acadia 2008 runs 142000 kms and I live in kuwait since yesterday the temperature gauge started go up and down frequently between 100 middle and two or three lines up while driving or stopping and ac is on. Please note the weather in kuwait now days is over 50 c. So is the temperature gauge changing is normal or I have to check the car.
Temp gauge going up and down. Im new to this forum and Im an owner of a frustrating 01 Qx4. The Problem is that my temp gauge is going up and down.
I have checked my coolant fluids and seem to be good I have replaced the thermostat and even replaced the water pump which was a pain in the a. The problem is still there. One very cold morning zero degrees Fafter sitting in the drive way all night the coolant temp gauge started fluxuating while I was driving.
Up until this time the truck would always sit at 210 degree any time of the year. On this day it warmed up to 210 then would go to 230 then go back down to 190 then back up to 210. Replacement thermostats come in varying temperature ranges and you can typically go up or down 10 degrees to fine-tune engine temperature for the application.
For instance you may opt to use a 170-degree thermostat in place of the recommended 180-degree thermostat if you do a lot of towing or a 190-degree thermostat if you want to pick up a bit of horsepower and increase. An accurate temperature gauge will always fluctuate because the temperature in the engine fluctuates. Usually the only time this is really noticeable is when the engine has been working hard and suddenly has to wait at a junction or.
One the reason a car heats up when stopped but cools when driving is that air is moving over the engine and causing the fan to spin. But this obviously isnt the only scenario. Here are some more causes of a hot temperature gauge.
Hoses provide a valuable function to a car. And when a hose breaks its generally bad news. Last year I bought an used C3 14 2002 and after a couple of months it started to show this annoying thing.
When I am stuck in the traffic after around 10 min the temperature gauge goes from normal 3 bars to the max beeps stays there for around 20 sec and goes back to normal 3 bars. It can happen once or several times. I have a weird problem.
When my check engine lights turn on my temp gauge reads fine on the halfway mark. But when the check engine lights is off the temp gauge goes up a little pass halfway mark. What is going on.
Before this happened I worked on the timing belt replaced the water pump and thermostat. On most vehicles the resistance of the sensor decreases as the temperature increases. At low engine temperatures almost all of the reference voltage is dropped as the current passes through the sensor and when the engine is warmer very little voltage is dropped.
Left the car on for about 30 min and it didnt fluctuate the engine temp at all. I turned on the ac and the temp would go up half a notch then fall back to norm while engaging the fan. I tried it again and the temp didnt move.
Drove around the block coasting in 2nd at 4k and the temp went up half a notch then fell to normal after I slowed down.
