Audi a4 1997 keeps overheating after bout 10miles (raises upto 100-110 degrees) Checked fan and still working and water circulating fine so could u provide any support in whats causing the problem?

checked water pump for circulating the coolant?
checked the radiator if the coolant circulated correctly?
thermostat renewed?
thermo switch checked whether is working?
fan switch checked whether is working?
checked whether the matrix could circulate the coolant?
ckecked whether there is any valve on the matrix hoses and is working?
have you bled the cooling system ?
have you checked whether you have a cylinder head gasket with problem and pressurized the water?
checked whether have a cracked cylinder head and on accelaration expanded the water hoses?
have you checked whether the radiator cap is working ok?
have you checked whether the radiator cap is with the correct pressure for the cooling system?
checked whether the cooling fan is working?

Overheating Due to corrosion block in Water Pump on Erratic engine coolant temperature or intermittent overheating can be caused by corrosion inside the water pump. ...Either condition reduces coolant circulation resulting in engine overheating.

Your radiator fan is probably failed. Pop open hood, watch temp rise, once past "normal " level teh fan should turn on. If not, you need to trouble shoot the rad fan. There should be heavy duty fuses and relays under the hood in an electrical distribution box. You should consult the owners manual or chart on the box lid. Of course the fan maybe bad itself. You can also try - turn on the AC, this will activate the 2nd (booster) fan, and should help prevent serious overheating but wont fix the underlying problem.
Good luck

Hi, well most likely this is the water pump? This is the commonest thing if the water isn't circulating. The pump will have to be replaced.

thermostat or water pump???? do both while your at it...

The engine overheat is due to inefficient cooling. Therefore, there is coolant in the radiator but if it doesn't circulate inside the engine water-jacket to remove the heat generated from combustion's chambers, then it still causes overheat. If this keeps happening then it can cause the engine head wrapped then leaking from the gasket as people called blowed head gasket. It could be: 1- Thermostat is not opened. 2- Water pump is not working. Before starting to replace parts, it needs to verify it it is the root cause of the problem. Take out the thermostat and run the engine to feel if there is water flowing inside the upper hose. A- If it is not then water pump is not working. B- If is, then run the car a few days without thermostat to see if it causes overheated. C- Running car without thermostat still causes overheat then there are some clogging up in the water jacket defeating the cooling efficiency--> Need a good flush. Good luck.

have you checked the waterpump it is 10yrs old could not be circulating the water, also have it pressure checked to see if it leaking or loosing pressure.

Possible early signs of a water pump problem. A failing waterpump will circulate coolent when the RPMS are high but when you slow down, so does the waterpump, thereby causing overheating.

bleed air out cooling system. put half antifreeze and half water .if you got too much water .it willl cause engine to over heat. antifreeze raise boiling point .220 degrees it wont boil away . water will evaporate 212 degrees.it will boil away .causing low coolant problems and over heating.

1. start the engine and leave the radiator cap open.
2. put a cardboard cover or a rug in the front of you radiator.
3. let it runs 20 minutes or more, see if it is overheated and see the water or coolant in the radiator circulated or not. If not, as soon as you have already changed water pump. thermostate and check the hoses, no leak, I think your radiator was blocked.

Did you put stop leak before?
