For best results use the floor vents and turn the blower on. However Ill probably change it with the coolant anyway 15 is worth the risk.
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.
Heat gauge going up and down. Reasons Why Your Cars Temperature Gauge Goes Up and Down. There are several reasons to why your car cant keep the ideal working temperature. These are the most common issues you can encounter.
This is the simplest issue to fix and the least dangerous one for your cars health too. 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.
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. 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. No heat and temperature gauge going up and down.
Eetemple July 4 2016 932pm 1. I have a 2002 Nissan Sentra. 2010 had inspection done and replaced upper radiator hose at that time.
Right after that I had no heat and the temperature gauge would go up to hot but then come right back down. Discussion Starter 4 Aug 22 2011. Fans functioning as normal.
Not getting the usual thermostat diagnostics ie. Shes heating up fine and where its going from normal to red and visa versa in a time of 5 seconds Id say there is no actual cooling problems. However Ill probably change it with the coolant anyway 15 is worth the risk.
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 and soemtimes less. If the needle goes to about the middle of the gauge that means the engine has reached normal operating temperature usually between 180 an 210F. It goes up quickly after starting then stabilizes.
Answer 1 of 7. If you are referring to the dip and rise as indicated by the temp. Gauge this is completely normal.
There is a thermostat in the head which controls the coolant movement. When the watercoolant heats to a set temperature such as 75 degrees C a wax pellet expands the valve in t. 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. 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. If it went up and stayed up you might begin to be concerned. If your temp gauge is not staying stable it keeps going up and down and you have PO300 code you will have to troubleshoot the problem until you find a solu.
When the thermostat is stuck open it can cause the coolant to circulate constantly resulting in the motor never reaching the correct operating temperature. The cooling fans may be working intermittently as a result of a faulty cooling fan relay or resistor. I have 2008 Dodge Grand Caravan 40 engine with 165000 miles.
Temperature gauge goes up and down while driving and stopping in traffic. I have had the the head gasket tested okey replaced water pump radiator fan houses pipes thermostat twice spark plugs. Lots of variables.
If you are driving it like a maniac for a few miles the temps will spike in the summer heat then back down as you cruise. Or you could be sitting in traffic with your AC on then begin moving to allow air flow into the radiator. Do you have the stock Thermostat.
That needle is just a. When the heating has not been on a while your pressure guage would read 1—15. Then as the heating came on and over the heating period the guage would prob rise to over 2 possibly up to 25.
Depending on what pressure is set at when cold. 1 cold to around 2 hot. 15 cold to around 25 hot.
The gauge should register 90C and shouldnt vary regardless of outside temp or load. If the gauge varies noticeably then either the thermostat is defective or the sensor is defective. If you still have warranty get it checked.
Read the last post in this thread. What temperature does your W204 run at. What is normal running temperature.
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 heater output. Once you have identified that the temperature gauge is continuing to rise you can attempt to prevent your car from overheating by.
Turning off the air conditioning and roll down the windows. Turn on the heater. Turning on the heater works by transferring heat away from the engine.
For best results use the floor vents and turn the blower on. Its the indicator of Up an Down with the light that says sensor. Up always is bad.
Im going with a seperate guage that will monitor water temp either scanguage or a seperate one like my oil pressure guage. If your needle is in the upright position for more than four hours call your doctor as this is a reare but fatel side affect. When youre doing the bleed.
Jack upelevate the front of your vehicle it will force any air pockets out of your heater core. Do not take the temperature gauge warning lightly by thinking its just acting up. Even if youve already replaced the cooling system components a year is a long time and anything could have happened.
A contaminated coolant system will cause inconsistent readings and requires a full bleed of the system to repair. If you have air or something else in the lines your gauge will probably be reading up and down as it passes through or stay cold if air bubbles get stuck on the sensor itself. A broken thermostat will throw your temperature gauge off.
