    Only some of the water (say half) just vanishes. The oil on the dipstick seems a little runny, it definitly not a coffee cream colour. More a black used oil look.



    It appears that the pressure in the raditor is very high. Taking the radiator cap off CAUTIOUSLY and slowly to release the pressure and to top the water level up. The water under extreame Temperature and Pressure bursts out of the overflow.



    With the vehicle at idle, the water bubbles out of the radiator.



    It must be the thermostat..



    What do you think.



    Thank you

Water temp needle should not fluctuate it gradually rise or drop. I had the same prob. try observing it with headlights on and off with aircon on. Does the temp fluctuate? try adding grounding wires from body(negative) to the engine.

When you say water dissappears do you mean all of the water or some? pull your oil dipstick and see if it is oil, or is it coffee cream color? if the latter than you have a blown head gasket, if you have someone that can change the head gasket good if not than take it to a mechanic.

effect causing a lowering of cooling efficiency. Do not remove

the thermostat, even if the engine tends to overheat.

1. DRAIN ENGINE COOLANT

2. REMOVE AIR CLEANER CAP WITH AIR CLEANER

HOSE

3. DISCONNECT ECT SW1TCH CONNECTORS

4. DISCONNECT ENGINE VIRE PROTECTOR FROM

WATER INLET AND RH CYLINDER HEAD

Remove the 2 nuts, and disconnect the engine wire

protector from the water inlet and cylinder head.

5. DISCONNECT WATER INLET PIPE FROM WATER

INLET AND LH CYLINDER HEAD

a) Remove the bolt and disconnect the inlet pipe from the

water inlet.

b) Remove the O-ring from the inlet pip e.

6. REMOVE WATER INLET AND THERMOSTAT

a) Remove the 3 nuts, water inlet and thermostat.

b) Remove the gasket from the thermostat.

INSPECTION

INSPECT THERMOSTAT

HINT: The thermostat is numbered with the valve opening

temperature.

a) immerse the thermostat in water and gradually heat the

water.

b) Check the valve opening temperature.

Valve opening temperature: 80 - 84CC (176- 183 deg f)

If the valve opening temperature is not as specified,

replace the thermostat.

c) Check the valve lift.

Valve lift: 10.0 mm (0.394 inch) or more at 95CC (203 deg f)

If the valve lift is not as specified, replace the

thermostatleedavidian_93.jpgleedavidian_92.jpg.

d) Check that the valve is fully closed when the

thermostat is at low temperatures (below 40CC (104CF)).

if not dosed, replace the thermostat.

INSTALLATION

1. PLACE THERMOSTAT IN WATER PUMP

a) Install a new gasket on to the thermostat.

b) Align the thermostat jiggle valve with the upper stud

bolt and insert the thermostat in the water inlet

housing.

HINT: The jiggle valve maybe set within 15 deg of either

side of the prescribed position.

2. INSTALL WATER INLET

Install the water inlet with the 3 nuts.

it sounds like a possible head gasket problem,you can get the fluctuation from combustion gases getting pumped into your cooling system and creating gas pockets,i would suggest taking it to a shop and have them do a block test to look for combustion in the cooling system to confirm the problem,that way you will know for sure,if it comes up negative they can also perform a flow test to make sure there is no restriction in the cooling system such as a plugged radiator or a bad thermostat,hope this sheds a little light on it

My 2001 VW JETTA GLS IS OVERHEATING


If one pipe from the radiator is hotter than the other one its usually the thermostat or water pump, seen as you already changed the thermostat id say its the waterpump.if you start the car when temp. is syill low enough to take the radiator cap off and leave it idleing and you see bubbles from the water at the cap then you possibly have a blowen head gasket etc

You can remove the thermostat and put in a pot of water and boil it.(should open near the stamped temp on yours, 195f) From what you have posted, ti seems that you have a partially obstructed radiator core and at present, it's just bad enough for the electric fan to deal with it. (you can actually see that the temperature fluctuations happen when the fan is on and off) If you do not clean out the radiator, eventually the fan will not be enough to lower the temp and it will begin to actually go into overheat.
