[QUOTE="pbleek, post: 1596510, member: 322743"] VW uses a plastic impeller on their water pumps, these tend to separate from the shaft and lead to overheating. You really don't have a choice, its way past due for a timing belt, the water pump is supposed to be changed at the same time. The 1.8 T is an interference engine, that is if the timing belt breaks you bend valves, there are 5 valves per cylinder. Its also an all aluminum engine, it does not like to be overheated. [/QUOTE]
