Default Thermostat housing bolts and coolant

Hi,
Does anyone know what torque the three bolts on the thermostat housing should be tightened to?
Can anyone suggest a decent long life coolant/antifreeze ? I know it is a HOAT coolant, but unsure of a suitable brand. CommaXHD G05 with Ethylene Glycol and Nitrile for trucks and vans with wet liners is the best that I have found so far(if compatible).
Thank you

From 2006 manual, this is the information I used.


2.2L DIESEL ENGINE
WARNING: Use extreme caution when engine is
operating. Do not stand in direct line with fan. Do
not put your hands near pulleys, belts or fan. Do
not wear loose clothes.
1. Clean all sealing surfaces.
2. Position and install thermostat housing (2). Tighten
bolts to 9 Nm (80 lbs.in.).
NOTE: Inspect condition of all clamps and hoses,
replace as necessary.
3. Connect coolant hoses and by-pass hose.
4. Connect coolant temperature sensor electrical connector.
5. Install generator (Refer to 8 - ELECTRICAL/
CHARGING/GENERATOR - INSTALLATION).
6. Close coolant drain.
7. Install engine cover (Refer to 9 - ENGINE -
INSTALLATION).
8. Connect negative battery cable.
9. Fill coolant system to proper level with appropriate coolant mixture (Refer to 7 - COOLING/ENGINE/COOLANT
- STANDARD PROCEDURE).
10. Start engine and inspect for leaks.

Thanks Alfie1 for the detailed reply, that will help a lot.
Ptcruisersteve, My pt is a 2004/5 on a 54 plate. I think it technically means from September 2004 to February 2005 first registration;so a 2004?
Thanks for the replies.

Does it make a difference?

I use this Mulder - from German maker Mannol (use their oils as well)

https://www.amazon.de/gp/product/B073V6VQG6

We need the -40 sometimes over here

If you can't get Mannol in the UK, just match the main spec (ie: mb325.3 - the Mercedes spec) on something else and you'll be OK.

While I'm at it - after much hunting - I went with this for the gearbox.

This matched the Toyota spec which matches (or might even slightly exceed - can't remember now ) the Chrysler ATF+4 and is half the price

Checking on the Comma site when I enter my car's reg it lists G48 as the correct/suitable coolant for my car. This is however, mb 325.0 not 325.3. Given that I do not know of any important distinction between these two, I will likely use the Mannol unless anyone knows better.
Cheers
P.S. Sinbad: where did you find the info regarding the coolant compatibility? I couldn't find anything in the handbook.

Cant remember how I arrived at it now mate - it was a month or two ago

Could be I matched it across MB engines models..? Although ours are a model to themselves, they're kind of a hybrid between the OM646 engine and the OM611 it replaced in Mercs.

If you check the specs on those two and MB325.0 covers either of them, I'm sure it will be fine. Most issues with antifreeze are whether it can react with materials used in the engine? - given the 646, 611 and our 2.2 are all of a family I can't see there being any probs.

Cheers
