Is the water pump driven by the cambelt or an auxilury belt on the Octavia TDI engines.

Thanks

Cam belt

Cam belt

:iagree:

"1.8 20v timing belts are difficult to replace. 1.8 20v timing belt drives waterpump and early engines had a plastic impeller which is prone to failure. If it jams, belt comes off and engine is wrecked. TDIs also have waterpumps prone to failure, but driven by an auxiliary belt so not so much of a disaster"

That was from Honest John:

Was hoping I could get away without doing water pump at cambelt change, but if it's driven by the main belt then oibviously i may as well get it done.
