Coolant problems Hi Everyone, Yesterday evening, my A7 had gave a 'Coolant temperature too high" warning sign and state: Let engine run with vehicle stationary, It had never gave me any problem except yesterday, and my a7 has only 25km on it, I can't believe this happen so soon, I've check the coolant level and it's normal, no leakage anywhere around the engine area, I start the car this morning, and idle it for 15mins, everything seems ok, the coolant temperature reading station @ 90 degrees. So I start to drive out and after running the car on the road for 5mins, the coolant reading begins to rise and very soon it reach to the max and the coolant warning sign lights up, so I had to pull over. Too bad the car had just past the waranty period, so any help or advise will be much appreciate. 2011 October A7 3.0 TFSI

Check to see if the radiator cooling fan operates when the problem occurs. If the fan doe s not operate, check for a blown fuse in the fan cooling circuit. That the engine does not overheat when idling for long periods seems to indicate the radiator cooling fan operates normally.

If the radiator fan operates normally when the engine is hot, the likely culprit is the engine thermostat, which then should be replaced. Thermostats can fail "closed," their normal position when the engine is cold. When that happens, they will not open to allow adequate coolantr flow as the engine heats up. An idling engine des not require much coolant flow to remain cool as it is not working very hard. When powering the car down the road, excessive heat is trapped in the cooling system and cannot be radiated by the radiator away due to the failed thermostat stuck in its closed position.

SOURCE: I drive a 2001 Chevy Tahoe with around 164,000 miles on it. I just got the power steering pump replaced yesterday and drove it last night and today and now when I turn corners it's making a really bad

Make sure that belt is tight. Make sure the connection to the pump is lined up correctly. Last but not least you may have to flush the whole system and refill it.

SOURCE: 2000 BMW 5series, battery will not stay charged, and engine runs hot

it does not sound like a battery problem from the info provided. It sounds like your battery terminal post is not connecting at the battery. A cable may have a bad connector end on it and the car runs on the alternator once started. Buy a ten dollar volt/ohm meter and check the ohms resistance in the cables by removing the cables from the battery first and then connecting the test leads to the ends of each cable. The meter should read the same as if the leads we're connected to each other. To test the battery change the ohm meter setting to read volts DC in the 20 to 50 volt range and connect red to positive ( + ) side of battery and black lead to negative side ( - ) of battery. Battery must read more than 11 volts for most modern cars to engage the starter circuit, most working batteries will show more than twelve volts. Jump Start the vehicle with the battery connected and with the booster battery disconnected again test the voltage and it should read 14.5 to 15.5 volts. you may need to replace one or both cables or have the ends at the battery replaced. obviously the cables that run the starter are good or a booster battery would not work either. good bluck.

SOURCE: Audi coolant

check the overflow tank and take the radiator cap off (when it's cooled down). if there is radiator fluid in either or both of them, you could have a stuck thermostat or a bad water pump. check the thermostat first.

Y dose the john dear 6330 run hot all the time even after it blowen out



Engine or hydraulic system overheating clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif clearpix.gif Coolant system low on coolant in 6020, 6030, 6030 Premium, 7020, 7030 and
7030 Premium Series Tractors.

]clearpix.gif//-->
Symptoms
After several hours of work, warning system indicates hot engine coolant or hot hydraulic oil.
Situation or Problem
Coolant level in reservoir is between the "MIN" and "MAX" range but engine or hydraulic system is overheating.
Summary
Air is entering cooling system, hindering coolant flow. Check coolant level. Fill to the "MAX" line on the coolant reservoir.
Bleeding Cooling System:
The bleed valve (see Operator's Manual for location) on the radiator must be closed when the tractor is operating. Open the valve when coolant is drained or filled. If the bleed valve is left open, coolant will internally bypass between the low temperature circuit and engine high temperature circuit causing overheating. When bleeding the system, open the bleed valve and run the engine with no load for 5 minutes at 1700 rpm. Then shut engine off for 5 to 10 minutes before closing the drain valve. Check the coolant level. If level is below the "MAX" fill line, repeat this procedure until coolant level stays at the "MAX" line.

Top up coolant with water


Water is fine since its warmer weather coolant is used mainly so it doesn't freeze as water would. You should be fine as long temps don't get below 32 degrees waters freezing point.

No DTC definition code found p1114


Hi there:
DTC P1114 - Engine Coolant Temperature (ECT) Sensor Circuit Intermittent Low Voltage/IAT - B Circuit Low Input



The engine coolant temperature sensor is a thermistor (a resistor which changes value based on temperature) mounted in the engine coolant passage. Low coolant temperature produces a high resistance 100,000 ohms at -40 oC (-40 oF) while high temperature causes low resistance 70 ohms at 130 oC (266 oF).

OPERATION
The VCM supplies a 5 volt signal to the engine coolant temperature sensor through a resistor in the VCM and measures the voltage. The voltage will be high when the engine is cold. The voltage will be low when the engine is hot. By measuring the voltage, the VCM calculates the engine coolant temperature. Engine coolant temperature affects most systems the VCM controls.

The scan tool displays engine coolant temperature in degrees. After engine start-up, the temperature should rise steadily to about 9O oC (194 oF) then stabilize when thermostat opens. If the engine has not been run for several hours (overnight), the engine coolant temperature and intake air temperature displays should be close to each other. When the VCM detects a malfunction in the Engine Coolant Temperature (ECT) sensor circuit, the following Diagnostic Trouble Code (DTC) s will set.



Hope this helps.

I have a problem with the code P0118 of my 2002 Jetta GL can you help me?


Make sure coolant level is as it should be. If level is low look for evidence of leak(s). Top off fluid if necessary. The engine coolant temperature sensor is a very common issue with these vehicles and may be the cause of your issues if no leaks are found. Also a faulty thermostat cans cause the sensors to read voltage high but most likely a sensor issue. The sensor is a potentiometer (variable resistor). The computer sends 5v through one of the wires this voltage goes through a resistor which will vary the voltage based on temperature sensed by the engine coolant temperature sensor. The sensor has a negative temparature coefficient meaning the resistance will go down when temperature is high and up when temperature is low. The less resistance the more of the 5 v gets back to the computer. The PCM detects this high voltage and set the check engine light on warning you of an issue. Whe this sensor goes bad it is usually accompanied by temperature gauge fluctuation or erratic operation and the cooling fans run long or all the time even though the vehicle is cold. Hope this helps.

Code 1 senser P0118 on a 2004 V.W beetle dicesel


P0118 for Volkswagen - (ECT) Engine Colant Temperature Circuit High

Symptoms:- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
(Inspect the following... Repair/Replace if necessary)
- Low engine coolant level
- Engine Coolant Temperature (ECT) sensor harness is open or shorted
- Engine Coolant Temperature (ECT) sensor electrical circuit poor connection
- Faulty Engine Coolant Temperature (ECT) sensor
- Faulty engine coolant thermostat

P0118 VOLKSWAGEN Description: The Engine Coolant Temperature (ECT) sensor is used to detect the engine coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the (ECM) as the engine coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of the thermistor decreases as temperature increases.
When is the code detected?:When an excessively high voltage from the sensor is sent to ECM.

I hope this helps! Let me know if you need further assistance.

I just purchased this truck n it smells like it is running hot?


Modern engines run at high under hood temperatures. If the temperature gauge is running normal and there is no signs of steam out of the water bottle, there should be no problem, but keep an eye on the coolant level and check the engine after a long slow run if you are still worried.

Over heating/ loss of coolent


If you are not loosing coolant on the ground. You may have a problem of a bad intake manifold gasket or worst a bad head gasket. The two things to look at are coolant in your oil, manifold gasket. Coolant out the exhaust, head gasket.
