Replacing thermostat and changing coolant 2021?

[Juddder]

Running in traffic yesterday my engine decided to run super hot, perhaps because I've had the original cats refitted for it's new MOT, so I think it's time to replace the thermostat and change the coolant and wondered if anyone who's done this recently has a live link to the low temperature thermostat that one can use to replace the original?

From reading this thread and this thread I think it's a QTH134K thermostat that I need but there is a note on the page for the very expensive RaceTech one saying to not use after market Fiat ones?

Also I have lots of Porsche recommended blue coolant in my shed so can use that if works?

Thanks for any tips in advance

On my car I ended up fitting Racetech Direct’s alloy housing that has a regular thermostat inside it. It was pricey but I was going round in circles trying to figure out the correct OEM part and also find a decent quality one.

Pleased with the Racetech one as it allows different thermostats to be fitted. They can supply with either a 82 or 74degC ‘stat. Think I took the hot one.

For the coolant I used Millers Alpine antifreeze BT blue. At the time it was cheaper on Amazon (supplied by Opie) rather than direct from Opie even with a discount. I went this route due to lockdown and wasn’t too keen on going out. It was £22/5 litres

Hope that helps.

I have this on my ebay watch list. It is the 85C stat. but the original shape. I think you have to be careful that the flow directions are correct.

I bought one from this guy two years ago - no complaints at all

Sorry - just realised, I might have bought it as a spare rather than fitted it - I simply can't remember (and I can't find it)
