Water Pump Failure - advice please
Discussion
My Griff 500 '98 34k miles has had the temp gauge at 90deg. Its been spitting out water but no major issue. However, its got more serious :
If the water pump is dead, I assume I cant even drive it to the garage. All agree or would you risk a 5 mile drive ?
- 1 There is a metalic grinding noise which just started today. I dont know the exact source but suspect the front of the engine
- 2 Temp 90deg, fans on but I can remove the blue cap from the expansion tank with ease - no pressure, hiss or steam

Good idea - just removed the belt & spun the alternator (smooth, tensioner roller & fixed roller all appear to spin freely. The water pump makes a noise (like a 50's police siren !)when spun slowly but give it a good spin & it sounds smooth.
Water is being lost via the blue pressure cap. Its 2yrs old. I will try a new part, think its VW origins. Anyone which VW make/model please ?

Just run it up in the garage. Water Pump is working fine, thermostat opening & fans cut in. Temp sat at 90deg and no water was lost out of the cap. Maybe I dont tighten the cap up enough after checking the coolant ?
Still puzzled though as to why there is no pressure in the expansion tank - again at 90deg with fans on I can remove the cap with no hiss or hint of pressure. Is this normal ?
(I will start a 2nd thread re metalic noise)

Sorted the water pressure issue ... I had a duff Blue Expansion cap. Purchased a genuine VW part and cooling system now pressurising as expected & no water loss. For reference, the VW part number is 443121321.
The cap on the right is the new part & correct for our cars.
I've also found the reason for the Metalic noise ... will update the other thread
