SOURCE: it only gets hot when

Hi

Your engine thermostat is stuck open and this is what is causing the problem. You will need to have a new thermostat fitted - Usual cost is between $15 to $30. Maybe less depending on thermostat type.

How the thermostat works is it remains in a closed position within the engines coolant circulating system to allow the engine to heat and reach its optimum operating temperature. The thermostat then opens to allow the coolant to circulate freely. When the thermostat becomes faulty it fails to respond to the temperature of the coolant. What has happened it that it has opened and is stuck in an open position allowing the water to circulate too freely around the engine - you will see a brief rise in temperature when the engine is worked hard but as soon as you come to rest the temperature falls back again as the thermostat is not closing when it should.

Solution - replace thermostat and all will be well!

Hope this helps. Please remember to rate my answer. Many Thanks.

SOURCE: check engine light came on, all fluids good,

You might have heard this,but check your fuel cap,if you did this,change your air filter,If that dont fix your problem,take your car to autozone and have them check the code,It doesnt cost anything.The temp guage is electronically sent to your dash,so check to see if it came disconnected off your thermostat,or from behind the inst,cluster.and check for any loose wires to the thermostat connections.

I have a 2008 Chevy Colorado and today my temp


when a temp gauge drops to cold ,it indicates a problem in the cooling system
temp gauge sender units need water to activate the resistance that makes the gauge read so a falling gauge indicates no water around the sender unit --- air lock in the system--faulty wire connection to the gauge sender unit
the ac unit is not connected to the temp gauge so there may be another separate problem there
the temp sensor is an entirely different unit to the temp gauge sender unit and the short term working would be from an altered coolant level from changing that sensor --air lock in system
the temp sensor connects to the ECM to activate the fans and monitor engine operating temp so as to keep the air/fuel mixture exact for the engine conditions
the temp sender unit just makes the temp gauge read
a faulty thermostat will either be stuck open and the engine temp will take a long time to rise or it will be stuck closed and that will cause an overheat very quickly

Replaced water pump thermostat temp sensor but temp gauge read all the way up when car is first started 3100 engine in 1996 monte carlo


For the temp gauge to read at full heat when the engine is cold is an indication of a short in the wire to the sender unit or you have connected the wrong wire to the sensor/sender unit.

Installing temperature gauge 1999 Mustang 3.8L


Congrats. Sarcasm is free.
I didn't see a question, so let's play the guessing game.

Air temp?
Water temp?
Oil temp?
Trans temp?
Your temp?

Do you need to know how to mount a gauge to the dash?
Do you need to know where to run the power wire for gauge light?
Do you need to know where to install the sensor on intake and or engine?
Do you need to borrow some tools?

I feel better after unloading sarcasm.

Now, I'm going to assume it's water temp.

if it's electronic, you can just remove the stock sensor wire from on/near the waterneck/thermostat housing and plug in the new wire.

If it's mechanical, you will need to install the new probe into a port where it can contact the water.

On my old 3.8 (1997) I changed to an aftermarket waterneck that had a spot to screw in a temp probe.

On my 2003 gt, I haven't upgraded gauges yet, but the water sensor is on the front passenger side of the intake. I will add a pic of my gt so you can see the placement.

With this type, you can just add your wires to it (splice them in) and keep both the stock gauge & the aftermarket.
Or just remove the stock wire, then the stock sensor, then install the new stuff.
it's the black wire near the alternator. (almost center right of the pic to the right of the pink fuel injector)

I have a 95 Gran AM GT with 3.1 auto. The motor will run until it gets overheated and boils over, but the fan will not start.I have totally flushed the system,pulled and inspected the water pump, changed...


Fan operates when coolant temp reaches 226 deg.F and shuts off at 219eg.F
fan is controlled by the PCM infuts from Eng. coolent temp. sensor & Intake air temp. sensor
the yellow wire is the 5V reference and the black wire the is the PCM ground sensor
make sure your not using teflon tape on the threads of the temp sensor.
it sounds like the PCM wont turn it on. check the harness for continuity between temp. sensor and PCM harness
clear connecter - pin 17 black, pin 31 yellow

Is your coolant actually boiling? Is so, you may need a new water pump.

Fuel gauge does not work at all


i recently did my chev s10 and they give you a new wire harness that you have to splice the wires and hook them up so it now has the same hook up. those wires are for your gauge as well as your pump. if your sending unit was not hooked up you would not go any where..take it back and demand this gets fixed.
