Water Pump ... old but unused

1
Hi all,
Finished replacing the water pump again today ... this time with a fresh NEW HEPU pump.

To recap, just a few years ago I installed a 20 year old but never used water pump that had been passed down through subsequent owners of my syncro. After fitting it a couple of years ago, it lasted about 8000klms and the shaft bush badly spat the dummy. My rudimentary stethoscope (long handled screwdriver) placed on the water pump with the motor running was telling telling me things were terribly awry with it and needed a transplant asap. The indicators were metal against metal sounding revolutions and noticeably noisy.

Needless to say I'm now an expert on replacing the water pump, a procedure that once filled me with terror but now take it in my stride.

My advice is ... if anyone is harboring an old but unused water pump in your spares kit, think twice about using it when the time comes. If you use it, you just may have to replace it .... twice!

Cheers.

It probably has a sintered bronze bush that, as supplied new, is preloaded with a lubricant.  If it sits in a box for 20 years, this will dry out.  This can be replenished by putting it in a container of the relevant lubricant and heating it to just short of boiling, then left to stand.  If the bush is going to be kept for a long time before use, leave it in the lubricant in a closed container.
