I have a couple questions regarding the water pump replacement procedure on the 2010-2012 Range Rovers w/ the 5.0L motor.
(FYI, I have the workshop manual docs already)
1) Are the two metal water pump gaskets (included with my Beck-Arnley pump) installed dry? Or is some sealant or dressing preferred?
2) When refitting the Pump, is it easier/best to fit the plastic oil cooler pipe adapter onto the water pump first or install it onto the metal tube on the engine first? Of course I will use a silicone o-ring lubricant on the two o-ring to ease assembly and avoid damage.
3)On that same plastic oil cooler adapter, there is an asymmetric round “disc” in the middle with a ridge on it and a generally odd profile. Does this need to be oriented in a specific way? It appears to fit in any rotational orientation on the water pump but perhaps there is a feature on the engine that will make its alignment more apparent when I actually have the old pump off.
4) Is it preferred to install the Water pump mounting bolts dry or with a dab or anti-seize on them?
Thanks in advance for your replies. I will be tackling this job tomorrow.
