    after you turn off the car the gauge goes all the way down (like less than zero). and starts with quater above zero, then goes to "hot". is there a chance to change only temp gauge? I dont want to change all speedometer

SOURCE: fuse of speedometer etc.

could be a short that doesn't touch until the "jerky" motion of shifting gears. Maybe a wire is resting near metal and everytime there is a motion it touches the metal and blows your fuse.
I would check continuity with ta voltmeter from your instument panel to the fuse box. and that will tell you if the line has a short anywhere between the two.
Any good 12v car audio mech can do this quicker and cheaper than a dealer.

SOURCE: 2008 infiniti g37 motor is knocking has 16500 miles on it.

Please change the oil now at the Nissan garage and watch the vehicle closely.

$100 is not so much like getting your car totally knocked.

Good luck and rate this solution/ suggestion.

SOURCE: HEAT NOT WORKING WHEN IDLE

Sounds like you may have a thermostat stuck open. Try taking a piece of cardboard and placing it in front of the radiato. Don't block it completely, but just limit some of the airflow. See if this helps.

SOURCE: After misfiring for about a week my 2002 Qx4

They changed the radiator and then told you need the engine overhauled? That tells me you don't want to deal with them! Any shop should have tested things out not just arbitraly start replacing parts. So unless your vehicle is still under warranty, then I would take it somewhere else to have them work on it.

Since I am not there to check out your vehicle, this is a WAG on what is going on with your engine.

Since you started off with misfiring - that could be a sign that your spark plugs are being fouled by oil or a few more things. But not usually an indication of a cracked block at least at that point.

But then you add the overheating into the equation - depending on how fast it overheats - right away (a couple of blocks driving) could mean either a blown head gasket or a cracked block but slowly could mean low coolant; radiator blockage, and so many more things.

If your engine was misfiring, you should have gotten an error code from your computer, which if acted on right away could have been a much cheaper fix. Now with what should like either a blown head gasket or maybe even a chrack block you are talking major work and dollars!

SOURCE: crank but does not start (Error code P0642)

p0642 = sensor reference voltage a circuit low voltage
p0300 = means random misfire
check firing order connections and must be in place.
check also cables especially the high tension cable and coils for required resistance.
primary = 1.0 to 0.5 ohms
secondary = 900 to 11,000 ohms (as requires per model)

Temperature gauge on my Peugeot 207 keeps going from normal to 0 and staying there no leaks visible no coolant lose


Normal to COLD?
You would only lose coolant if the engine was overheating - or, as you say - a leak.

It's probably a faulty temperature sending unit - these are common failures. You actually have nothing to worry about. The unit sends a signal from the engine to your temperature gauge in the car. Even if the unit is faulty the engine is still operating at the correct temperature - it's the signal to the temperature gauge that is wrong.

Your temperature sensor will look something like in the image below:
26054640-ncuktxo4qw3omcx4ef1trshf-4-0.jpegIt's inexpensive and quick to rectify. A new sender unit can be fitted within minutes. Give a mobile mechanic a call ..

I read your question about the car heater.. No, the sensor wouldn't cause the heater to blow cold air. That fault is either air in the cooling system/heater system, or a blocked heater matrix.

Remove your radiator cap/coolant bottle cap. Open the heater controls to HOT and set on maximum. Start the engine and let it tick over - see if it forces any air out of the system when the heater should begin blowing hot.

If the heater still blows cold it may have a blocked matrix. Try a bottle of radiator/coolant system flush to see if that dislodges the blockage. The instructions will be on the bottle of coolant flush

Check for low coolant, you might also have a sticking thermostat. Alot of fords get air pockets, make sure if it needs coolant to let it run for about 10-15 min with the radiator cap off.

The radiator keeps boiing, even after a short trip and the car tends to overheat, also have had to replace 2 engine coils in the last few weeks. Actually a suzuki crescent cultus.


Hmm, open the radiator cap and check if the coolant is calm if it is vibrating or tends to jump out the head gasket needs replacement

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.

Heater temperature fluctuates which effects the temp gauge


Sounds like SOUNDS like thermostat and a pressurised coolant flush would be a good place to start that thermostat might be opening and closing due to the above perfect place to start.John

Overheating and heater not work


there is a valve on the water pump and one on the thermostat housing open those up one at a time until you get a little bit of antifreeze come out then tighten them back up. All you will be doing is bleeding the air out of the cooling system. my car was doing the same thing after I changed my thermostat.
