hey guys today when i got into the car and tuned it one the coolant light came on, which at first i thought it was odd, but after quick thought i moved the car back from its original parking spot and took a look to see if theres a spot. guess what ??? nothing. then i open the hood thinking that the sensor plug might be lose or something and to my amazement low and behold... overflow tank is empty !!!!
WTF is going on !!!
its a 99 A6 Quatro Tip.
looked a the oil right away hopping that its not the headgasket, oil is fine (was a bit low but it wasnt creamy)

any ceratin areas where i should look ???

 

id check the hoses first off

 

The A6 has the after run pump aswell doesnt it? - that is prone to leak

 

Check the tank itself there could be a small crack in it hence no spot. That's where mine was.

 

well after a good look and nothing to soo got mad and tossed in a flourescent dye into the coolant. will see where that sucker is comming from.
so far my finger is pointing at the water pump since it started to make some noise.

 

did you replace the timing belt? maybe is time to do so also

 

I got the same thing going on let me know how much or how long it took to fix.

well if this is the same thing that happened to me awhile back, your going have to get a new water pump and prolly a timing belt but you should change that if it is the waterpump anyways. I think they said my spindal in the water pump wasn't spining anymore. it's going cost a little over a grand if its the same problem

 

my car is nearing 200k's so its time for it anyway...
right now in the neighbourhod of 195 need to be thinkming about the 200K tuneup
anybody knows what needs to be done at the 200K scheduele ???

 

Possible coolant leak: Check the reservoir for cracks. If the reservoir is ok, check under the intake manifold. If it's a 2.7T, most likey the secondary coolant pump. If it's a 2.8, its most likely the coolant pipe seals under the intake manifold. If it's none of those, then it must be the water pump especially with that high of mileage. If you do replace the water pump, it would be a good idea to replace the timing belt, tensioner, rollers, water pump, and thermostat. Hopefully this helps, good luck.
