6300,6300l,6400,6400l Tractor Radiator

The temp. gauge reads in the red when the actual temp. is 176 to 179 F. I checked the temp with a thermometer at a peacock in the block and at the radiator, both read the same. The guage tests OK . I turned the key on and pulled the wire off the sending unit and it goes to the left. If I ground the wire it goes to the red. I have put in two different sending units (both new) and no change. The tractor will do this at idle when it is below zero.

The dealer tells me to live with it. I asked him to do a D-tech and he won’t. Several people run this machine and I don’t think they should have t

Experienced gardeners share their insights in answering this question :
You need to take the temp gauge side of the dash off and check the circut bourd[physically inspect it]to see if the board is badf.If it’s not then you probably need the guage replaced.{can’t beleive they said live with it}If you don’t get sattisfaction contact me again and i can fix this.

How to Identify and Fix Common Gardening Problems ?

If the engine has insufficient coolant or air in the system, your temperature gauge reads hot all the time. If your gauge is reading hot, double-check that your engine isn`t overheating. Make sure you have sufficient coolant in the system and that no air has got into the system when you are changing the coolant.
If you find that you`ve got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.
The most common cause of faulty temperature readings is a broken coolant temperature sensor (CTS). The part, which is normally located near a vehicle`s thermostat near the base of the radiator (consult your owner`s manual or repair guide) can get gunked up and fail.
If this light turns on, it means that your vehicle has detected that the coolant temperature is too high. This indicates that your engine is likely overheating. If your engine is overheating, it is recommended to pull your vehicle over to a safe place and turn off the engine for at least 20 minutes.
The engine temperature gauge on your car`s dashboard gets its input from the coolant temperature sensor. A faulty sensor can cause it to fluctuate erratically as you drive.
If you notice that your engine overheats, the coolant temperature sensor could be the problem. At times, the coolant temperature switch may fail such that it starts transmitting hot signals permanently. This causes the computer to erroneously counterbalance the signal, thereby causing the engine to misfire or overheat.
You Find Incorrect Readings on the Temperature Gauge

The temperature gauge will read cold until your vehicle has had time to warm up, after which, it should register the average temperature. If it continues to read too cold or registers too hot, then there is the chance that the temperature gauge should be replaced.

The instrument cluster fuse, also known as the dashboard fuse, powers the gauges and displays on your vehicle`s dashboard. This includes the speedometer, tachometer, fuel gauge, and temperature gauge. If this fuse is damaged or blown, it can cause these gauges to stop working or malfunction.
On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor. If it`s not working, the fan won`t turn on when it needs to, which means the engine might overheat.
Normal Temperature engine temperature gauge

Most experts agree that your engine should run between 195 degrees and 220 degrees. In ideal situations, your needle will maintain a posture right in the middle of your gauge.

As your cruising down the road and you notice the temperature gauge is up to the “H,” your car is “running hot” too hot. The next thing that will happen is your car will start to overheat.

How do I change the temp gauge on a john deere 6400
ANSWER : The temperature gauge is built into the instrument cluster and it needs to be changed as a unit.Try removing the wire from the temperature sensor and ground it to the frame of the tractor to verify that you do need the instrument cluster replaced,ground that wire will drive the gauge to hot if the gauge is good and nothing will change if it is defective.If grounding the wire made it work then you need a temperature sensor.Good luck and let me know how you make out!
