Im having to top up my coolant every three weeks or so, goes from max on the reservoir to the low water alarm warning sounding/flashing. Ive had the coolant system checked for leaks, but nothing turned up, and they reckoned it must be internal. What is the most likely cause? am wondering if maybe its the water pump or a leak in the head?? I have noticed a wierd sucky/slurpy noise from the engine which kind of cycles every 10 seconds or so at idle.

any ideas peeps? its had new belts and a water pump about 10k miles back, and now getting on for 140k ...its an 02 exaa 2.5tdi :ILU:

i would be concerned about putting stuff in your cooland as if the water pump decided to seize then the cambelt will let go and bang goes the engine .

was the water pump changed on last cambelt change and when was that.
