MINI OE Thermostat Failures | ITB Episode 53

- While the failure rate on the Mini thermostat has been a fairly common occurrence in the shops, you can minimize comebacks after the initial repair if you know what to look out for.
The thermoplastic housing around the thermostat utilizes a silicone gasket. While it’s an ideal for high heat applications, especially in the close quarters of the Mini engine bay, it does not fair well when exposed to leaking oils.
When it comes in contact with oil, it has a tendency to swell. Over time this can cause the thermostat housing to crack, triggering a code. If you swap it out for a new one without finding the source of the oil, you’re going to continually run into the issue.
Step 1:
Check the area for leaks.
Step 2:
Do the necessary repairs.
Step 3:
Make sure all the surfaces near the thermostat assembly are clear of any residual oil.
Step 4:
Do your install.

I have two minis in my shop right now both with thermostat failures and I'm by no means a mini specialist. These cars just suck, I mean how many manufacturers have figured out how to make a reliable small 4 cylinder car? It seems like the engineers for mini were making bets about just how crazy they could make these cars and still get their designs approved.
This engine won engine of the year 8 times in a row!! haha. yeah its a great design on paper being super compact and utalising lots of plastic parts to minimise manufacturing costs, but fk me its a dog to work on due to the tightness and is very fragile due to the plastics
@@loccomoffo1000 and it's a feckin Peugeot engine, it's a nasty engine to work on, much more fiddly than the R53 engine's which were Chrysler engine's; How it won engine of the year 8 times is beyond me...
Piss on this. My sisters mini has code for the thermostat. Now that i know it’s common failure im telling her to leave it. Not leaking doesnt get hot. Dont worry.
Worse thermostat made
*car made
I’ve got 140.000km on my R56S and changed the thermostat housing for 3-4 times. What’s the case? Why is this part failing so often?
Honestly? Because it’s a piece of shit, poorly designed thermostat housing made of plastic. They almost always crack on the elbow leading to the crossover pipe/water pump. At least the water pump was updated from a plastic to metal housing… If that doesn’t fail, it will electrically fail internally either with the map controlled thermostat or the integrated coolant temp sensor. Which could potentially cause excess fuel to be dumped into the cylinders and fuel wash or flood the cylinders, causing a no start condition.
Oh yah, and when the housing cracks and you lose all your coolant, there is no coolant temp gauge and more often than not the cluster won’t notify or throw a check control message indicating an overheat. Seriously, I’ve seen melted thermostat housings and valve covers (more plastic) due to insane cylinder head temps and subsequently seized engines with no overheat messages displayed on the dash or stored in the control modules such as the kombi/instrument cluster. All because of a plastic thermostat housing cracking/leaking. To top it off, there is like 4 different versions of the thermostat on R56’s and they all require different wiring adapter harnesses or sometimes even came with a remote mounted temp sensor located in the radiator hose between the radiator and thermostat. Good times. Sorry, rant over.
@@TheAhdoodoo I dont understand why someone (3rd party) has not manufactured a metalic part to replace that plastic poorly designed thermostat, im certain it would sell good... no?
Mine also 140km n leaking
I replaced mine 2 yrs ago and the code is starting to pop up again already
I’ve replaced mine twice in the past two years and the P0597 code just popped up again 9 months since last swap
