coolant tank or cap replacement?

After 100K, I'd replace the tank regardless. There is a record of the plastic seam failing. I just replaced mine not long ago with one of these.

A buddy helped, pliers spread and slide the clamps down and push the hoses off with a flat blade screwdriver. Bolt the new can in place and lube the two pipes with a bit of coolant and the hoses slide right on and work the clamps back up.
Use a baster to suck the fluid out of the old tank and set it aside to replace when you're done.

The metal tank is about 25% more than an oem tank. Well worth the peace of mind. My oem tank had no leaks, but I replaced it with the metal tank as a ten year wear item. Figured that would be the last time the tank would need replacing. The fluid in the metal tank can only be visually inspected by removing the cap as had to be done on the oem tank since they turn a dark brown color as they age. It is recommended that the metal tank be kept half full of fluid which is about 18 ounces. I made a dipstick out of a clear drinking straw marking the half way point at two inches from the end with a Sharpy pen. Insert the straw, cover the end, remove and view. The simplest way to check the fluid level is to remember visually where the level should be above the baffle. The metal coolant tank is the easiest and most cost effective remedy for an "easy to fix weak link in the cooling system". PS-I reused the oem cap since it was functional. I do however keep a hot spare in the boot. Good luck.

Tio Bary you do have an interesting point. Here is what my coolant tank cap looks like, but i cant really know if there is something missing, but i cant see an oring available! Can anyone one have a look on his own to see if it looks like mine? Just remember we are talking about a 2008 R56S coolant tank cap here.

Hello Genik,
There is an O ring on the inside of the thermostat housing cap. You can see on the inside threaded center part a little bit inward.

My 2007 MCS needed replaced. I just did the whole expansion tank also as the bottom of the tank had a hairline crack.

You chose to go back with OEM rather than aluminum? Curious why?

I was doing all the cooling system at once, we had them in stock. Also the Forge ( metal ) one at the time was about a month out, they were sold out due to being so popular.

There is no separate part from MINI. You Might have some luck as a A/C store with o rings.
