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. Reasons the temperature gauge reads cold.
This lasted for 2 days and then it went back to dropping the water temp, killing the a/c.
Car temperature gauge goes up and down while driving. Many of the car owners face problems with their car’s temperature gauge. However, as all car parts wear, some malfunctions can cause your engine’s temperature to either go up or down, or even fluctuate during driving. Temperature gauge is fluctuating while driving.
If the thermostat is behaving correctly, it will only allow as much warm coolant out of the engine going to the radiator and cooler coolant to come into the engine as needed to allow the engine to maintain a temperature. So, take your car to a mechanic and make sure that the wires are safe and intact. It is not uncommon to have a gauge break or not register any longer.
On this day it warmed up to 210 then would go to 230, then go back down to 190, then back up to 210. Another reason the temperature gauge could read cold is if the thermostat in the vehicle stays open. Immediately park your vehicle and turn off your engine.
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. I have this recurrent problem with my 2002 honda crv. My thoughts are of course electrical.
If the temps are going down when travelling at speed, this means the thermostat is allowing too much coolant from the radiator into the engine and. As long as the needle does not continue to move up while you’re driving, it’s not something that should be considered alarming. With the development of technology, car overheating has become an old issue.
Thank you for asking about your honda accord. Drove it around for about 10 mins and the car stayed at 210 on the gauge (as it should) and the a/c worked fine. Up until this time the truck would always sit at 210 degree any time of the year.
I have had the the head gasket tested okey, replaced water pump, radiator, fan, houses, pipes, thermostat (twice), spark plugs. I was driving my car today and noticed the temperature gauge wouldn't go past the the top of the 2 bottom bars. Some cars have temperature gauges that have been overused, possibly because the vehicle overheated in the past, causing the gauge to fluctuate too often.
This could be the thermostat valve, radiator hoses, radiator fan, the temperature gauge, or the coolant itself that circulates around cools off the engine. Happening more lately wheezing traffic causing engine to sound likes it's working harder to accelerate and temp fluculates When you notice a continuous increase in the level of the temperature gauge of your vehicle, you should not take this likely.
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. Its wire might have become loose, due to which you must be getting false indications. If the temperature gauge still reads cold after the engine has warmed up, the gauge may simply be broken.
Temperature gauge goes up and down while driving and stopping in traffic. In most cases, the temperature gauge suddenly goes up. If your car thermostat goes up and down, then chances are that there is a connection problem between the temperature sensor and the temperature display positioned inside your car.
The problem is that my temp gauge is going up and down. The temp gauge can't fluctuate that drastically without it being some sort of circuit/relay/sensor issue. However, that didn’t rule out the possibility of your car breaking down in the middle of the road.
Usually, if the temperature gauge shows the temp going down while driving, it is indicating the thermostat isn’t functioning properly and may be stuck open. I have 2008 dodge grand caravan 4.0 engine with 165,000 miles. This constant fluctuation of the gauge can cause the tiny spring or lever inside the gauge to dislodge.
Im new to this forum and im an owner of a frustrating 01 qx4. It would remain at 1/2 mark after warming up but while driving it would sometimes go all the way to 0 and then come back up till 1/2 mark. Last year my temperature gauge started acting up.
One very cold morning (zero degrees f)after sitting in the drive way all night, the coolant temp gauge started fluxuating while i was driving. This fault can be the reason why your car temperature gauge goes up and down while driving. On most vehicles, the temperature gauge reads cold until the engine has run for a few minutes.
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**. How to fix cars running hot but not overheating? 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.
Temp gauge going up and down! My temperature gauge keeps going up and down when. I changed the thermostat within the last 30k so i'm ruling that out unless it really went bad that fast (it's only been.
The problem is still there. Reasons why the temperature gauge reads high if your temperature needle goes up and reaches the red zone, it could be an indication that your engine is. You need to know that a certain range of fluctuation is normal, but if the temperature fluctuates wildly, you’re looking at a problem with your cooling system.
And for the first time i did not reach full operating temp after my 10min drive to work, it was still one bar short. It fluctuated up and down (depending on if i was on the gas or on hills) a few millimeters. 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.
We recommend replacing the thermostat.
