I am on my third water pump in three months. When my first pump failed,it was rapidly leaking coolant and my coolant was completely drained by the time I reached the shop. On the second pump (which lasted 2 months), I noticed a high pitched whining and a slow coolant leak (via the level in the reserve tank) before the pump completely failed as before. The third pump lasted only three weeks and I noticed the same symptoms as before (intermittent whining from engine and dropping coolant level) but brought the car in for repairs before a complete pump failure. The mechanics at Pep Boys (who have replaced all of the pumps) have said that their pump may not be compatible with my vehicle (2000 vw cabrio) and are ordering a pump from the VW dealership. I am skeptical, as it seems very unlikely that so many pumps in a row would be defective. Is this a common problem with VW models? Is there anything else connected to the pump that could be causing these failures? I have also been told that the belt on the pump may be too tight or the tensioner may be faulty. If so, why wouldn't the mechanics have seen this? Is there a way to check this myself? I have very limited experience in repairs, so any advice would be much appreciated! Thanks!
