I say tapered bc the ones I pulled out (I broke on of them) had a rounded bottom

Also another question on this — is a Febi replacement thermostat okay?
Yes Febi Bilstein theromostat is good quality.
Fiat EPER says 2010-2011 panda thermostat bolts are M8x25
The bolts are M8 x 25mm length (8mm girth). You can buy some from B&Q and cut them down to the right length. File the ends round if you wish but not entirely necessary. 8.8 bolts (marked on the bolt head) are stronger quality like the originals. The round end is just to help locate them in the factory I believe.
Might be worth changing all the front core plugs if you havent already. When the clutch is next changed - make sure you replace the core plug behind the flywheel!!! - ask me how I know!
It's quite common for people to run Fiats without proper coolant mix unfortunately. I have not replaced the rear core plugs on my 24 year old Seicento sporting and touch wood they are still ok! Almost same engine block as the Panda.
I wouldnt worry so much about flushing the system with all that fancy stuff, I would just use a garden hose
. New radiators are around £50 so if necessary, not the end of the world.

Are we sure it's not M6x1,0x25mm
The pip on the end doesn't matter, it for automation so the bolt don't cross threads
I buy flanged grade 8.8 zinc plated they are around 10p each

Refer to Eper parts catalogue on this website.
The earlier thermostat did use M6 bolts. Some petrol Panda in 2009 and 2010 onwards the thermostat was updated and it uses M8 fixings.

Are you sure
post the part number or direct link on eper would be better, or tell me where I am going wrong
Because when I look it up myself
Petrol 2011 with updated thermostat
Shows this part number
Which does not show the thread sizes
But online seller show M6
The other number used
Comes back as a bolt and washer
M6X22
Which is why I asked if you were sure in the first place
Seeing as the original poster has the bolt out it should be easier just to measure it

Maybe we should all have a few spare M6 & M8 bolts just in case

Yep 8.8 is the grade
It's a high tensile bolt
Take the bolt with you but I can't see any thermostat held on with anything other the M6

Also this diagram shows a gasket for the thermostat — I don’t think mine has one
Mine does have an o-ring though

And weirdly Haynes doesn’t have anything about a gasket (just that sealant ring)
Yours
2011 1.2
Thermostat should come with a new rubber seal
There's no other gasket or sealant required
It's slightly confusing as pre 2010 used a completely different type of thermostat

Thank you so much
Unrelated, but I suspect a blown piston ring — loss of power, higher oil and fuel consumption
Troubleshooting would involve compression test, right?
And then if ruling out spark plugs or anything else, the repair would basically be like doing the HG again + removing the sump to get to pistons and crank, right?

Hello all!
Hope you are marvelous and having a wonderful Wednesday!
I am happy to report that, fingers crossed, the thermostat replacement has gone very well, and I am indebted to the forum once again. Thank you all.
I managed to get the right size screws, and the new thermostat has the temperature right where it should be on the dash, and it feels like a bit of power has returned to the engine!
It also feels great to know there’s a new part which is all nice and shiny lol.

I do, however, have another problem that really concerns me.
I have very heavy oil blowback, and recently it consumed a lot of oil (light actually came on, but I did the oil like 3 months ago).
I did know that one of my Air flow sensors (the one on the driver side of the inlet manifold) gets covered in oil frequently, even after cleaning the inlet manifold inside with an old tshirt),
But I also noticed the cam cover breather tube to the air filter assembly is full again with mustard-like crap (though pil cap and oil look clean and uncontaminated) and I just noticed the oil on my throttle body last night when I did the thermostat. Picture attached of throttle body.
Long story short, my worry is a blown piston ring. I had a concussion when I did oil even further back, and I overfilled it (miss counted the quantities I put in — should have known better when I was doing it all with a headache).
any advice would be greatly appreciated — one day I might learn enough to give back (or maybe one day I’ll even earn enough to give back lol)
