What is the coolant temperature gauge on a New Holland tractor?
Late Summer, my compact tractor (Case DX40) coolant temperature gauge started to read high. The Case DX40 is almost identical to the New Holland TC40DA. I posted on a tractor forum and got some very useful information shown below. The gauge is a Stewart-Warner and is apparently what it calls a “bi-torque” gauge.
Why does my fuel gauge not read Hot?
From your temperature data presented, your tractor is not getting hot. Your temperature gauge is apparently reading high. Could be a defective temperature sending unit, or a defective temperature gauge, or a defective voltage stabilizer. Does your fuel gauge seem to read high as well?
Why does my coolant temperature gauge read high?
So if it were not for self-heating of the sender by virtue of the hot-side current the gauge would be fairly immune to supply voltage changes. A higher-than-normal supply voltage would however result in the sender resistance dropping excessively through self-heating, giving a high gauge reading.
What kind of temperature gauge is a Stewart-Warner?
The gauge is a Stewart-Warner and is apparently what it calls a “bi-torque” gauge. The gauge read well into the red zone after only about 10 minutes of running. Replaced thermostat and sensor. Both items tested OK on the bench afterwards. Gauge pegs high, as expected, when sensor wire is grounded.
What should I do if my temp gauge reads Hot?
Check the temperature gauge inside the car. If the temperature now reads hot, then there is a open wire in the sending unit. You should immediately have the temperature gauge repaired.
How big is a water temperature gauge on a tractor?
6732154E water temperature gauge for IMT tractor fits in 539 506 533 560 540 57 536 1978 models and more … . Only 8 left in stock – order soon.
What should the temp gauge read on a New Holland tractor?
If stuck open, the gauge can read normal on a hot day and working moderate to heavy loads but barely move off the cold peg on a cool day with light work. If you’re continuing to use the tractor, I’d keep track of the exhaust.
Where is the temperature gauge on a car?
Unplug the temperature gauge from the sending unit. This is usually located to the right of the engine. Turn the ignition key to the “On” position. Do not start the car. Ground the temperature gauge wire to the engine. You should use jumper wires to ground the temperature gauge. Check the temperature gauge inside the car.
