I'd say you have a faulty thermostat, be it new or not. You can't post conmments that contain an email address.
The water pump's pressure-side has a small outlet that sends water through the heater core; when you turn the heat on, a valve in the heater core's water inlet line opens and sends coolant through the core. If you want to learn more about this, you can check out our guide: In some rare cases, there could be a problem with your engine control unit if the temperature information is received first to the ECM, which therefore sends the data to the cluster. Also, when I have the heater on and fan on high, the temperature gauge drops as I’m going down a mountain and not pressing the gas pedal. Thanks, Collins, Lagos- NigeriaHi my daughter has a Peugeot 207 1.4 petrol. The next most common problem is a faulty temperature gauge. Re: Temperature gauge goes up and down while driving
... my car warms up and the temp gauge sits right in the middle. You do not want to replace the engine control unit if there’s not a problem with it, because they’re often costly and require coding.The most common causes of a coolant temperature gauge which stays on cold are with the coolant temperature sensor itself. A stuck-halfway valve will increase the time that it takes for your engine to warm up and will cause temperatures to slowly creep up under load. Engine temperature goes down while Driving! First, we have to find out the functions of the temperature gauge. On older cars, you usually found a However, on more modern cars the engine control unit needs the coolant temperature as information to calculate the right fuel-mixture at all different temperatures. What things could cause the temperature gauge to stay on low? About a couple of months ago, the temperature gauge on my car was fluctuating while I drove. Most likely you have a stuck thermostat. Some models, like Nissan and other Asian cars, use two different coolant temperature sensors; one for the engine control unit and one for the instrument cluster gauge. I have been working with cars since I was 16 and I'm specialized with in-depth Automotive diagnostics. When I checked the dashboard, the temperature guage was still at the middle and I continued my journey until the car stopped again. There are several causes why your engine temperature gauge stays on cold. When you unbolt the housing, you'll find the saucer-shaped thermostat sandwiched between it and the block. They’ve also “burped” it numerous times. During my early days of driving, I drove my car for a few kilometers without realizing that the engine malfunction indicator was 'On' due to a rat bit. But I would check the thermostat or replace it and replace the cap. And I noticed that the engine was hot and the water in the radiator pouring out. As for the temp sensor, if it is bad the guage will flicker, representing a bad connection. You can't post conmments that contain an email address. Gauge still stays on cold.I have 2007 pontisc g6 2.4 temp gauge worked fibe then noticed it was stuck on lowest teading n the check engine light had came on took it auto parts place said was sensir or liw coolant or thetmostat well car heater is great and was on fill line in coolant as i left the parts store i noticed the needlecwas workibg again which it did for 2 days n onve again stuck on lowest reafinh just by touchibg sensor to assurecit was snug n placevit started working sgain so that mean the sendors not actually bad n could b lisecwire?I own a 2008 Chevy trailblazer Sometimes my thermostat Gauge works sometimes it does notBut it always blows hot airIt is never cold I had the Sensor replaced in it Still doing the same thing Could it be my thermostatI have issue on Toyota Corolla 05 temperature sensor which I have change temperature sensor and cluster still not working but I find out I that it work Rich the engine control box but the cluster not moving.what causeOk i have a 2014 nissan sentra am in the process of changing the oil or fluid from the transmission.
