Can this freezing weather bugger your water pump?

Reason I'm asking is last night at around 9pm with a temp of minus 5 I started the 147 and it made a terrible sound on start up. Hard to describe the sound but it abated after the engine warmed up (5 mins).

Same thing again this morning - same sound (temp of minus 10) and same thing again half an hour ago (minus 6).

Once car is running till engine is warm it is ok but before that it makes a terrible sound.

Anyone?

If your coolant fluid has the right level of antifreeze in it ....it should be ok i reckon.

I think antifreeze is normally good to -25°C so as long as
you've got a proper mix it should be fine.

Don't top up with neat stuff as it's the 50:50 mix that is quite important.
Too much can cause overheating at the other end of the scale.

I am thinking it is more likely a tensioner for the aux belt, either the fixed or sprung one. Mine sounds nasty until it gets warmer, after a couple of mins, and on the 145 too. Getting replaced next week.
