In bleeding my coolant system after installing a new 180 degree t-stat and some dexcool, a few turns in and out of the plastic bleeder screw, the top broke off. The plastic had seriously degraded. So I'm on the hunt for a new screw. So, I'd recommend replacing it on a regular basis. Piece of mind for a few dollars and a couple of minutes.

Coolant reservoir
Looking for a group consensus, I guess. As the reservoir is a perishable item and these engines, or at least my 03 4.6, are sensitive to overheating, do you replace them as preventative measure or wait for a leak. On rockauto they are about $30.

These are works of art. Now I know what to save for.
Yes, for PEACE of mind you may want to replace the upper hose assembly if it hasn't been renewed in nearly 2 decades. We've sold many of the metal ones and they seem to work pretty well.
The plastic pieces are only available with the hoses, wheter you go to rover or buy Uro parts, or another aftermarket brand, apparently.
I purchased both items HERE: https://www.sportscarcentre.ca/land-rover-parts-and-accessories
Good prices on both compared to other suppliers.
Both are installed. I have peace of mind....for the time being.

On the above link, they mentioned a throttle body heater. Is another area of preventive maintenance? How long should the replacement plastic bits last? The aluminum ones should outlast the entire truck.
They also list the lock rod and intake hose. 2 more areas I didn't know were troublesome. How troublesome are they?
There are some subtle differences in the 2 Tees. Look at both the bleeder screws. One is beefier and does not use an o-ring or rubber washer it appears. More material in the screw head would allow it to be tighter and maybe seal better too.
I only got a year or 2 out of the TBH on my P38, same ones as the DII. If I had seen the Canadian one I would have tried that a long time ago. Sold now so it does not matter.

Both massive issues on a D2, absolutely necessary to replace, especially in a corrosive area
I sorta get the intake as it becomes rusted mesh, but what is the issue with the rod. Mine looks fine.
