mini cooper s 2000 overheating
After a period of storage i have started using my mini Cooper S Again 00 G 23
After a short while the expansion tank starts bubbling .
i have checked the following
thermostat replaced
new coolant
Head Gasket oil clear no evidence of a damaged or blown gasket
fan cutting it at temperature but not colling it down sufficiently
any ideas what next ?

Re: mini cooper s 2000 overheating
As the car has been sitting up the first thing to check is that the stat is opening.
MPi engines run a normal temperature around 100 deg. C so it is important that the cooling system holds pressure as water boils at a higher temperature under pressure. Is there any steam coming out. MPi expansion bottles are known to crack where the hoses join the tank.

Re: mini cooper s 2000 overheating
Terry,
What thermostat are you using? Mpi's run hotter than carb Minis. I had overheating problems with my old 98 mpi but it was a common problem with a sensor which was activating the fan. There was a factory upgrade which cured it. The other possibility is that your 20-year-old rad has silted up.

The other known issue is the quality of the expansion tank tops. As Woody says, the system needs to be pressurised to work properly.

Re: mini cooper s 2000 overheating
Try replacing the coolant header tank cap, I replaced mine with one from a 2006 Mini Cooper S.
Instantly stopped any heating issues on my 2000 Sportspack

Re: mini cooper s 2000 overheating
Check the cooling fan speed. It may be cutting in OK but may not be turning fast enough. I had this problem with one turned out to be bad earth to fan. 9

Re: mini cooper s 2000 overheating
I had a problem with overheating on my 2000 Cooper Sport, the coolant was flowing through the rad but not being cooled , a new rad solved the problem but I tried everything else before replacing the rad.
