Aux water pump ?
« on: 08 March 2012, 08:58:38 »

If the aux water pump packs up what problems would it cause ? The thing that sits piggy back on the rad ... whats its purpose if you have a water pump on the engine block anyway  ::) Anyway to test it ?



Noticed this while looking at the for sale bits here ...from rob  :y

Only runs when the engine is stopped. It circulates a little coolant after the engine has been stopped when hot, to prevent "after-boiling".

Can be tested by putting 12v across the terminals.  :y
