Is that another name for stop leak that puts junk into the coolant? Bad idea in my opinion unless it's a get me home attempt. You'll end up with blockages where you don't want them
Is an engine replacement in a 4.6 P38 a complicated job?

This stuff? The reviews on Amazon show around 25% of users had problems with it, or it didn't work for them. But you must be in the 75% that found it fixed the problem, at least for a while.
Also: https://www.v8developments.co.uk - these people? Looks like a very useful operation - thanks for the intro.

Like this Silverline one? For £78, seems like a useful kit to have.
Amazon has some cheaper ones with Chinese names, but at least I have heard of (and used) Silverline before...
I have used it on the Astra I had, had a leaking head gasket after over heating when a hose clip failed, it never
overheated after replacing the clip but, was losing coolant via the exhaust, followed the instructions to the letter
and, it cured it, still hadn't lost any coolant when I got rid a year later.
Did you still use OAT coolant with it? according to the label, it's only safe with blue antifreeze, can react and
cause blockages with other types, apparently.

That could explain why it didn't work for me years back as car was on red anti freeze

Silverline pressure test kit - fell at the first - the "Land Rover" adapter doesn't fit, nor does any other one in the kit. Back to Amazon it goes. Anyone know of a kit that actually fits a P38?
Also, a question on the header tank level. If I cold-fill to the "Cold Level" mark, when hot it rises a little, to just over the joint that runs round the middle of the header tank - is that normal / correct?

This kit has on adapter that fits P38 tank.

yes it should rise a bit, if i recall
pressure increases, the amount of air is unchanged, therefore it must take less space

Water expands with heat so some rise is normal, that's why there is an expansion tank.

Funny stuff, water. Expands when above 3C, and also when below 3C, and of course even more when turning solid.water expands when it gets cold anorl
So the top of a frozen lake is floating ice, and the lowest level of water at the bottom of the lake is the densest at +3C. Fortunately this gives fish somewhere to survive, albeit somewhat chilly.
Coolant expands with increasing temperature too, but as the air in the header tank is also under pressure, it acts to push the coolant level down, hence my question. The complexities of the RR cooling system are such that I wanted to know what happens in real life, with all the forces and counter-forces present in the header tank..

That looks exactly like the kit I had, but cheaper and with a different maker's name. The green adapter is supposed to fit, but is far too wide in the stem. The pink one nearly fits, but not quite. Have you got one of these kits?

We found the UV dye in the coolant best. Droplets all over the dip-stick.

V8 developments are very good but there was a hell of a wait last I heard.

You should know that air compressors easier than water
