Just an update on this; I finally got round to fitting the engine under tray last night.
I used this pattern part from ebay:
https://www.ebay.co.uk/itm/163427558075
£42.99 delivered

And used Stainless steel M8 x16mm bolts with large washers to fit it.
The tray fitted perfectly and seemed to be made of very good quality plastic.

The only minor issue I had was that the two rear mounting bolt holes had corrorded too much for the bolts to screw in, so I just used a couple of cable ties to secure it.

I wouldn't worry much about the rear bolts, my plate has already broken at one of them, it will stay in place even without these, as long as the center bolt is in place. Speaking about bolts, Volvo also has them and they are inexpensive - for once https://www.youtube.com/watch?v=VYuCMbtiZaE

or you could splurge and get one of these:

I got one on sale for my 2010 V70. Works great and makes for much easier access for oil changes. Interestingly it did make the engine a tad noisier vs. the felt liner that was on there.

Indeed as that is the purpose of the tray to comply with slow drive past noise regulations , petrol engines don't have one as quieter .

That is a lovely part, but it would be even more expensive for me to have it shipped to the UK and pay the import tax.
Not to mention that would be around 20% of the value of my car

That's probably pre 2005 before the cost cutting :-)

How do you measure what you consider an engine running overly hot?

Eg the other day I ran the car at 1500rpm for 15mins while doing an oil flush and the outside temperature was about 22 to 24c.
After the above the oil filler cap was quite hot to the touch ie it was almost burning my hand.
Is that too hot?
This was before I fitted the undertray and with the hood open and the front of the car jacked up.

I would not be unusual for the engine itself to be 100C or more to the touch , enough to burn you ! Then you have the Exhaust manifold and turbocharger/s which can be 400 c to 600c + depending how hard the engine is working .. that will burn your skin off immediately and flood the engine bay with super hot air ... The underbonnet temperature is known by the ECU and the radiator fan will run harder if it all gets too hot even with the ignition off ...
