Question about 2000 Nissan Sentra

2000 Nissan Temp control

This problem just started a few days ago. My temp reading for the vehicle used to stay steady at middle ground. A few days ago it started doing some extreme fluctuating from about a 1/3 up the line all the way to the line before the H. I've added more coolant, more oil to the engine and it still does it. It doesn't steam or anything. Also when I turn the heat on, it stays warm for about 10 minutes, then the air gets fairly cold. I have no idea what could be causing this. Help?

Well first off i would just have the thermostat changed out cause this will flaux if bad and soon it will stick
engine temperature for most vehicles should run around 200 - 220
anything hotter your engine will melt

also clogs in radiator system can make over heat bugs in radiator clogs system
your a/c throw out bearing could be wearing down on vehicle and maken it run hotter because now the vehicle has to produce more force just to spin a/c compressor
but i wouldnt worry that right now doesnt sound like its it but keep eye on it


do you have digital gages for vehicle or manual switch cause for it getting cold while using heat makes it sound like there is a switch malfunction or digital guage mal. the wiring has some how been run backwards

That is a proper operating temp. after the thermostat opens. If it reads 200 degrees when cold you need to check your temp gauge and sensor.

2000 bettle 1.9L turbo will only start if you unplug coolant temp sensor


Hello and welcome to FixYa!

If that's the case, I strongly suggest that you replace the coolant temp sensor. Looks like it's faulty and grounding the circuit. The car's computer can detect it that's why it won't start but once you disconnect it, it will for the coolant sensor is bypassed.

Hope this helps and thank you for using FixYa! Have a good one!

2000 Jeep Grand Cherokee with a 4.0L engine... the temperature only rises to about 150 degrees and stops... sometimes lowers a bit even at highway speeds. Normal operating temp is about 210-215 degrees. ...


The thermostat controls the temp of the engine. The temp sensor tells the gauge what temp to display. If the heater is still putting out a lot of heat then it may be a false reading temp gauge. If however the temp is noticibly cooler then replace the thermostat. A stuck open thermostat would also cause the engine to warm up slowly. check for a loose/dirty connection at the plug on the temp sensor.

2000 maxima has erratic idle on cold days and will stall out on extremely cold days. Also, have noted antifreeze leak (on ground) on those really cold days. Car runs fine once it reaches normal operating...


It sounds like an engine temp sensor is open.. When your engine is cold or anti-freeze is cold your ECU or ECM gets a signal from the temp sensor for cold engine start. It would make sense that it works fine when hot because the resistance on the sensor is a lot lower. Take an ohm meter if you have one and check the resistance across the temp sensor pins. When the engine is cold the resisitance should be really high. Start and warm up your car to normal temp and check it again. It should be a lot lower now. If not replace it. Hope this helps.

Intermitant temperature


Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.
