Omega General Help / Re: Play in V6 water pump. How much is too much?
« on: 07 December 2015, 17:18:31 »Following on from Saturdays thermostat change and coolant flush I now have a significant coolant leak down the front of the engine. Accept that the 'stat/transfer pipe would be obvious candidates but using an endoscope/boroscope laptop attachment that area looks dry so thought I'd have a feel of the water pump.
There's definitely a 'rock' there, so wondering if there is an amount of movement permitable or if any play would point to a likely source of leak.
I've had it in the past where a flush and a change of coolant seems to find or exacerbate leaks that were not previously an issue.
On a side note, the aux belt tensioner assemblywas loose, literally hanging on by a thread or two of the bolts. And this car like many others has supposedly been professionally maintained.
Off to modify a coolant cap now.

Correction, the tensioner was hanging by the last thread or two of one bolt. The only thing stopping the other bolt going down the road was its resting on the cable guide for the alternator.
