There is a guy here called Marinus, who runs a company that brings in parts from Australia ( Terrain Tamer ), and believe it or not ... sometimes his prices are better than what I can get from my local spares shop, like brake pads for example, so maybe give mein a PM and ask him for a price. It will get couriered to your house. Great quality parts too I must add.

Nope, looks good.
The old one is a non Nissan thermostat
I have completely removed mine. Will this cause any major problems? If so where is best (cheapest) place to get a new one?

Yes, removing the thermostat entirely can cause the waterpump to cavitate. There needs to be some resistance...

The even bigger problem is that it uses a bypass thermostat which means you CANNOT remove it. A bypass thermostat is 2 sgage, once its is on working temp the flat "washer" at the bottom closes off a port which is very important otherwise most of the water will just circulate through the engine.

In short, when the thermostat is closed - water circulates through engine only
When thermostat is open - water circulates through radiator only
When thermostat is removed - water takes easiest route which will be mostly engine only and some water through the radiator.

Michael, this is a 4.5.

That engine doesn't have a bypass thermostat.

But your comment is definitely valid for the TB42 and TD42 engines!
