Twin Turbo Z32 Water Pump maybe

I have a coolant leak dripping from just in front of the sump only when the engine is not going,[nil pressure in radiator] this is normally caused by a faulty water pump seal unless someone knows of this problem and can advice me where it is leaking from.Cannot see where the leak is coming from with out removing the fan and radiator.If it is the water pump, Can any won answer me? do you have to remove Harmonic Balancer to remove water pump.

 

I'll soon have a spare water pump if you need one.

 

Sounds like your pump seal is on it's way out if you're getting leakage from the little "tell-tail" hole at the bottom, and yes particularly after engine is turned off when heat soak sets in. It's letting you know your pump needs replacing. Do the complete 100,000km service while you're at it.

 

Yes you do need to remove the damper as well as the lower belt cover.

 

Thanks I already have a Z new water pump

 

The 100000k service was done about 20000Klm ago

 

your from the shoalhaven hey, where abouts?

 

Just wondering -- Was the waterpump changed at the 100,000km service and if so was it a Nissan OEM Waterpump that was used ? (interested in the reliability aspect).

 

might not be the water pump. Could be the short rubber hoses above the pump that join the the outlet coolant pipe to the heads

 

It was the water pump.Replaced the water pump with a Nissan OEM pump.OK now thanks.
