Hi if you look at temp gauge it is usually about 3/4 of the way up to the top any higher and this usually means thermostat gone or head gasket gone temp between 50 80 degrees depending on outside temp and how you drive diesel cars run a bit higher due to the amount of extra compression the pistons need to make the diesel flamable if you need further help let me know ok.
Also alot of newer cars run at temperatures lower than what i just said usually below half way but anyhing upto 3/4 of the way up is fine if it reaches the top this means engine problems or rad fan not working or thermostat not opening allowing the coolant to be pumped round engine properly as the thermostat opens when the water reaches a certain temp

    No worrys if your temp gauge is going up to high then it could be one of a few things one test you can do yourself is when you driving is turn the heater onto hottest setting then turn the fan on to blow the heater.
    If the air comes out hot then your thermostat is fine if its blowing warm or cool or cold air then this is your thermostat needs replacing should be cheap to replace part only costs between £5 to $10 uk sterling or $8 to $15 dollars us but thats just the part they wil charge for labour but as its only 15 min to replace shouldnt cost that much.
    If the air is hot then that isnt going to be the problem.
    problem 2: this could be a water leak on water pump allowing air in and water not to be pumped round engine properly this is a bit more expensive abot £20 to £40 or $35 to $80 for part plus an hour labour for fitting
    3rd problem:Now this is the expensive problem it could be that your cylinder head gasket has gone allowing water to mix with heat from exhaust causing the temp to rise the parts cost about £40 to £60 or $70 to $100 for part but the expense with this repair is the labour as depnding on you vehicle could take between 4 hours and 8 hours but depending on what the garage charge for labour you could be looking at about £500 to £700 or $800 to $1200 depending on the hourly rate they charge for labour.
    Hope this is some help to you let me know if you need further assistance or advice ok

The car coolant temperature gauge, if it has numbers should not go higher than 195 degrees in winter if you have a thrmostat that is rated at that temperature installed in your car.
If you live in a warmer climate you would have a lower temperature themostat rated about 180 degrees.
These temperatures are what your engine temperature will reach before the mechanical thermostat opens to allow coolant to flow to the heater core that the fan blows into your car.
If you have just a visual indicator with low to high range, it should be reading about in the middle of the range to be operating normal.
In extremely hot locations, it will run a little higher than that.

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

I have a Daihatsu terios kid 2002 Motor fan not operating temperature gauge is normal about center of the gauge


The fan only operates when the engine/coolant temperature exceeds the thermostatically controlled fan. At idle observe the dash engine temperature and fan. Before the gauge reads above normal the fan should operate.

Truck never reaches operating temperature


low operating temperatures is an indication of an air lock in the cooling system
gauges need the sender unit to be fully immersed in coolant to work but if they are not then the variable resistance material in the sender bulb cannot accurately relate to the coolant temperature
example if you have leak develop in a good system and you do not regularly scan your gauges like a good drive will do. it is possible that you will smell a dying engine yet when yo look at the gauge it will be reading cool to cold because the coolant has dropped to a point where the sender is no longer in contact with the coolant

Heater donot get hot whil running


It could be a plugged heater core or heater control problem. I assume the blower is working, but the air is cold. The first thing to check is the coolant level, make sure there is coolant in the resivoir. Next see if the temerature gauge reaches the normal operating temperature range. If the gauge reads cold most of the time, it would tell you that the thermsotat is faulty and not allowing the engine to reach full operating temperature. If your car doesn't have a temp gauge, the blue cold engine light might stay on for an extended period of time. The thermostat is supposed to not allow coolant flow in the radiator until the engine reaches operating temperature. If you drive the car for a couple of minutes, from cold start, the radiator or upper hose should be cool until the engine reaches operating temp.

could possibly be a head gasket problem. check the oil and make sure the coolant is not mixing with the oil... also thick white smoke out the tailpipe is a good indicator of a bad head gasket

Normal engine operating tempurature can vary from 180 to 220 degrees depending on the age of your car and what kind of modifications it's had done to it.
Your 01 Escape is going to be normal in the 200 to 220 range.

I have a 1998 Saturn SL2 DOHC with ~140,000 miles. The car runs great, but I am having trouble with the coolant temperature. When first starting the car up in the morning, the coolant temperature gauge...


When you said you replaced everything, did that include the temperature sending unit?
The temperature sensor just operates the cooling fan or fans for the radiator.
The temperature sending unit operates the temperature gauge in the dashboard. If that thing is faulty, the gauge won't work right.
If you did change the sending unit, it could be possible that the computor is screwing it up, but in my 41 years as a mechanic I never heard of it, when a computor goes, nothing works.

There are two sensors connected to the thermostat housing and i need to know which sensor is which and what they control. on cold days i cant get started


The larger of the two is the coolant temperature sensor. The other is the actual gauge temperature sensor. The coolant temp. sensor gives information to the cars computor & when the car reaches a predetermined temperature, the computor changes the ignition timing allowing the car to run at normal operation temperature settings. The temperature sensor gives info to the dash board gauge &/or temp. warning light. The reason you can't start on cold days is that your coolant temp. sensor is stuck in advanced mode & the timing is to far advanced . To remedy this problem change the coolant sensor. Good luck!

2001 dodge stratus engine temperature gauge spikes occasionally


Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.
