Bleeding LS1 after waterpump replacement

[ConstantVelocity]

That's weird then. Can you get a video? Most commodores whine a little bit if you listen for it. Or is it an obvious whine?

The whine has also faded with further driving I think I just needed to let the new parts wear in a little. Thanks to all those who helped.

Is the VX LS1 engine bay slightly different to the VY-Vz SS series?

Mine was easy to do, almost entire system drained, did up hoses, poured 5 litres red coolant on overflow tank then 5 litres demineralised water and topped up after running car for 10mins or so with random 3000rpm squirts of the pedal and done.

Took for a drive, checked when got home and de-squealed belts

You are wrong about using de-mineralised water read the link https://www.hyperlube.com/blog/blog/why-you-should-never-use-distilled-water-in-your-cooling-system/

Yeah the radiator overflow is relocated under the guard from memory.

Not for a LS1

 

[Mookie01]

VY or VZ have a bleed screw on the drivers side top of the radiator that is a bleed screw, pretty sure it's VZ. Cant remember. But as the overflow and therefore the fill point for the rad. is the highest point of the system it should self bleed to an extent.

That is for a V6 they have a bleed screw not the LS1
