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. Find out where its leaking and fix it.
Just doesnt make sense.
Engine temp goes up and down. 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. However as all car parts wear some malfunctions can cause your engines temperature to either go up or down or even fluctuate during driving.
You need to know that a certain range of fluctuation is normal but if the temperature fluctuates wildly youre looking at a problem with your cooling system. There can be various reasons behind these temperature fluctuations. Overheating is a common problem in vehicles.
This is a consequence of complex systems functioning together in sync. Additionally if you have a question like why does my engine temperature goes up and down you must consider that this problem can vary according to the situation. 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 operating temperature. It is a 1999. The temperature gauge goes up and.
It sounds like you need to change the thermostat in the engine its located inside the throttle body of the engine the main hose running from the engine usually the bigger hose. An engine or coolant for that matter can not physically go from 250 degrees to 230 degrees in just 3 seconds and then bounce down to 220 and back up to 240 in the next 15 seconds. Just doesnt make sense.
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.
F150 35 EB 2019. In Utah around 37 degrees today and my engine temp going up hill kept going up to 230-236 after a hill assent though its go back down. Engine coolant level is good oil is good.
Fans keep going on and seem to stay on. This is the first time this has happened and I am not towing anything. Its pretty common for the temp to fluctuate this much certain locations for the temp sender are more sensitive than others.
If you are worried about air trapped in the block drill a couple 18 inch holes in the perimeter of the thermostat flange. This will drain any air pockets in the block within a week or so. Stowaway is right there is air in the system because you have a leak.
Revving it up forces what little fluid is left to hit the temp sender which brings the gauge back down. It also splashes a bit of hot fluid into the heater core to give you some heat. Your coolant level is low because you have a leak.

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. Most causes in temp gauge fluctuation is due to air pockets in the coolant system a failed thermostat not opening up properly at normal operating temps or a failed thermostat temp sensor reading.
Those are the only things that I could think ofbest of luck to you. 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. Brought it back to mechanic changed thermostat and both things ok only part way home. Started riding with coworker only driving to her house 7 miles away and still temperature.
Gauge needle moves up and down while driving. Locate the coolant temperature sensor it is usually located near where the upper radiator hose goes into the top of the engine drain the coolant from the petcock at the bottom of the radiator and unscrew the sensor to replace. Posted on Jul 28 2009.
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. In this case it comes down to bad engineering of the engine in terms of placement of the temp sensor.
The temp sensor cant get accurate readings until the thermostat actually opens. This is why the sensor shoots up to hot and then dives right down to normal once the thermostat finally pops open and allows the water to flow into the EGR manifold. 5 Jun 28 2004.
The one on the rad is the fan switch I believe. The temp sensor should be on upper hose neck on the engine. Check your coolant level and leak.
Air pocket will mess up the sensor reading. In this weather the thermostat should be open all the time anyway. Start the engine with heaters on full hot going into the cabin etc Undid the bleed screw slowly until a steady stream of coolant came out then tightened it up Let the engine warm up and then did the bleed screw again Once the engine was as hot as it wanted to go I switched the engine off and put the cap back on the tank.
The phone number is 9714-314-3408. I hope the issue is able to be resolved for you quickly. 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.
