Cooling - Not a problem

Hi everyone

As this is not an 'issue', i thought this was the best board to post to

Without making this post turn into a support group, i need some re-assurance if possible

So basically, i have a 2001 Mini Cooper that i absolutely adore. Of the 18 cars i have had, this is my favourite i would say. But a problem in my brain is stopping me from enjoying it to it's fullest and it isnt fair.

The problem is that i am constantly waiting for it to overheat...even when there are no signs it will, the cooling system is perfect and I know there is no reason for me to worry about it.

I NEVER worried about this sort of thing before until my last car (BMW 328i E46) had a fan issue and got hot a few times.

I have my Mini constantly plugged into a bluetooth OBD scanner that displays the coolant temp on my car and, as i believe it should, it goes to 96 degrees, drops to 90, back to 96 etc while driving and when i get stuck in traffic if creeps up to 99 after a while, at which point I start to panic, put the blowers on full speed and heat.

I have read in a few places that the fan will only kick in at 105-106 but i am scared it wont. I asked my mechanic to check it and he kindly let it get hot and confirmed the fan kicked in as it should but i am still petrified that it wont and i will boil the engine and cause huge traffic jams

I am sorry for the post, i am just so angry at myself for worrying about something that i know *should* be fine.

My worry is getting so bad that i am now leaving home early and coming home late in order to avoid being stopped in traffic.

I fear i need a psychiatrist as opposed to a forum but...

Hi ya

It just shows you care about your car this is not a bad thing. It's actually nice to here for a change.
You are doing the right thing buy keeping an eye on the coolant temp as the gauge is there for show only.
Normally with the first stage fan problem can be easily checked by doing a resistance check on the plug for the fan easy and quick I check mine every tine I service the car just to keep an eye on it :-)
The temp that your car is running at is correct so nothing to worry there.
If you have aircon and your sitting in traffic and your getting worried you can put that on this will run the second stage fan.

Anyway try not to worry to much enjoy your mini :-) you look after it it will look after you :-)

Hi there, thanks for the post. I appreciate it

I need to get my Aircon sorted actually, thank you for reminding me!! Needs a re-gas i think

Such a stupid fear for me to have but is actually causing me a lot of stress.

I am going to buy a scangauge to help put my mind at ease i think

Hi ya

The scan gauges are very good but another option got you is a ultra gauge

UltraGauge OBDII Scan tool & Information Center

Also the nice thing with both these are they can read and reset fault codes
So if you do get stuck read the code post the code someone will help :-)

Thanks, I can't wait to get one

Got caught in traffic today and let the car get to 108 degrees before I had a meltdown (1st stage fan didn't seem to cut in) and so put the blowers on.

I am going to have a heart attack at this rate

If it went to 108 the fan should have cut in at 105 really
Check the fuses and relays Incase also
Get someone to do a continuity check on fan to check the first stage resistor
It takes about 5 min max to check this

There is a black plug on the right hand chassis leg as you look at the car it goes to the fan. Disconnect it
There are three wire one brown and the other two blue with a red trace line
Go between the brown and one of the other wires (blue with red tracer) you should have continuity do the same on the other wire ie brown to the other blue with red tracer you should have continuity.
If you have continuity on one but not the other your fan resistor is gone and needs changing it's an easy fix

You will need one of these

Them I used water proof butt splices to install it job done, to install all this takes about 1:30 hours from start to finish

As the water system is under pressure and has antifreeze in it (which has a temp inhibitor in it) the boiling point is close to 110 dec C not 100.

Most cars with a dash gauge will find its doctored to sit at 90, this is because people assume hitting 100 is an issue when it's not. My Cooper S has sat nav so doesn't have a temp gauge at all!
