Omega General Help / Re: Play in V6 water pump. How much is too much?
« on: 08 December 2015, 16:57:34 »Seems it was the water pump. Happily there was a bleed hole (top surface, genuine GM) and with the pulley off and the system pressured it ran out a treat, even faster when the shaft was rotated.
Also happily the replacement pump (FAI, £47 from local factors) has a bleed hole and the pulley bolts did not need shortening.
Curious that the three pump mounting bolts were equal length. I'm sure I read somewhere (probably Haynes) they would be different lengths and should be replaced accordingly.
- glad you're sorted.
