Sounds like the antifreeze in the radiator was/is weak and allowed it to freeze. It MUST be December.
DO NOT DRIVE IT until you've thawed it out.
The way to do that is start the engine watch the temp guage. It will begin to over heat. BEFORE it over heats to much, shut it off and wait. Slowly this will thaw the water in the system.
Once thawed (be patient) drain and refill the radiator with a 50/50 mix of antifreeze and water.

    ....a stuck thermostat will give the same stmptom.

    Follow the top radiator hose down from the radiator to where it connects. This is usually where the 'stat is located. Drain the radiator, remove the hose from the thermostat housing then remove the housing.

    You'll see the thermostat. Replace it and the gasket. Remember, the "spring" part of the stat always goes towards the engine.

Heat problem. Heater only works sometimes. Blows out almost AC temperature majority of the time. No engine overheating problems. May or may not be related to actuator issue (vent always open)


Check to see if your heating system is properly filled. Air in system can often prevent the proper flow of hot coolant into the radiator core resulting in your issue.

They are certainly related. The PCM monitors the temperature of the coolant, and makes sure the coolant has reached operating temperature before it goes into closed loop operation. Closed loop is where the PCM is constantly metering fuel, timing, etc based on ALL inputs, including the O2 sensors.
So your engine is not warming the coolant to operating temperature. First, make sure you have the coolant system fully serviced - topped up - so the temperature sensor is always immersed in coolant. If you are still having the problem, your thermostat may be stuck open, allowing the coolant to circulate unhindered through the radiator and keeping it below optimum temperature. Another thing to check is your cooling fan(s) - it/they shouldn't come on until the engine is fully warmed up (unless you have the air conditioning turned on).

With a defective O2 Bank 1 front sensor you would expect a poor warm engine running operation.

The before catalytic O2 sensor controls the fueling function to the engine. The mixture air/fuel ratio is calculated from the input from this critical sensor.

With a simple scan tool with graphic function the operation of this O2 can be observed, and diagnosed.

Suggest borrow or if car drive-able take to a parts store that will perform a complementary scan of the O2 function.

These are heated sensors and the heated circuit electrical connection could be the problem.. Exhaust leak, blocked catalytic converter, broken wire are all possible causes. By graphing the function and comparing to bank 2 diagnostics are relatively easy.

The reason at cold startup the engine is OK is that until the O2 heats up the engine is running open loop and the O2 is not hot. To be operational the O2 must be hot.


Hope this helps?

1998 beetle overheating and heat doesnt work


To start with, the cooling system is a sealed system, so anytime you have to add coolant it went somewhere. Either an external leak onto the ground, or an engine leak were the engine is burning it.
If you added coolant and the heater is not working all the time, the system could have air pockets which would need to be expelled.

My 52 plate 2.7 crd wont start. no fuel getting thru engine spins over good


The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms

Ok.. I got in the car this morning.. went to the store & the car started to sputter .. when i went to 3rd gear it sputtered like it wasn't getting gas??


Maybe the gas gauge is not correct and it did run out of gas?? Otherwise read the following.

Hello


The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Charging System Failure Light


This is a common problem with these cars. I have had it come on also a couple of times. No need to worry unless it stays on.
