Doubt it .... but definitively time for a good flush of the entire cooling system and replacement of the antifreeze..... BUT PLEASE USE QUALITY ANTIFREEZE, and NOT the cheap stuff. This is the ONLY time other than Head Gaskets on a TD42 where I would recommend Nissan Original.

Or you can use aftermarket, but don't buy cheap, and mix 100% to the correct ratios. Cooling fluids should be changed probably every 100 000Km, but would have to check the manuals.

I do mine every 50 000 odd Km
Thank you for the tip! She is due for a service. But overheats all the time and I'm not sure if it is because of a leak or air lock or the thermostat that has been removed.
I'll go get her serviced this week and purchase quality ANTIFREEZE.

If the thermostat has been completely removed, there is a pretty good chance the waterpump has been cavitating and is now shot...

It it has only been modified so that it can't close, then the above does not apply.

Thank you Peter. I will arrange to get them both replaced and engine serviced too.
