for some reason I don't get any posts to my questions, So here goes another question !
I posted a question about adjusting the water pump belt.. Well it cannot be adjusted it has to be fitted by removing the three bolts that hold the pulley on then put one bolt back in and then putting the belt on !
Still my A6 is over heating I have just changed the thermostat that is located in the water pump housing !.. We will see if that cures the problem.. It is not the viscous fan unit as I have just ripped that out and put in a 14" fan unit from Kenlow.. What a cool kit...
Any way the symptoms are..
Idleing the car does not over heat.. As soon as you put power to the engine the temp goes up my fan system kicks in . the temp still goes up..
If you touch the hoses they are hot, yet the expansion tank is not....
If you open the expansion tank you see allot of bubling and it fills backup and the rad fan kicks in again !
THere is no signs of water in the oil or oil in the coolent
Any idea's ?
Hopefully this might get a post or two !
