Hi folks,
I am at my wits end (ok it wasnt a long trip), I have cleaned out the radiator, changed (after testing) the thermostat, changed the water pump (no just the normal one), changed the radiator cap x 3, changed the top and bottom hose, disconnected the heater (in case it was leaking). Mike Byron pointed out the fan was on backwards so that was corrected, he also corrected the timing and adjusted the tappets. First test run 5 mins around the block and it once again was boiling!

It has been recommended that I get an electronic dizzy, a morris 1100 radiator, a motor bike radiator (hooked in where the heater goes).

Has anyone had similar problems with a Clubman that wont keep its cool?

thanks,

Jim

Have you tried a cleaner through the block or a reverse flush of the block ? You've fixed or replaced everything else that could be a contributer so time to look further . How about the carb and throttle response , is there a chance it could be letting air in somewhere or too lean at certain revs ?

check your mixture...


running lean is a great way to overheat...

get the mixture right and see how it goes....

wow a constructive post form cush!

you may need to flush out your whole cooling system, chances are there is a blackage somewhere. then refill it with a good quality coolant and see how you go.

my clubby was having overheating problems earlier this year, it turns out that the bypass hose between the block and the head had clogged u with rusty scaly crud, as i wasnt using coolant. now i know!

Hi folks,
By the colour of the plugs, id say it was running riches before the dwell angle was adjusted. The block looked clean, but I must admit I havent pulled the motor down for a good look. I have 3 motors on the deck now, so it may have to wait until I get the other clubby running.

I really should have paid more attention when my uncle tried to teach me about motors....


Then again I was only 5.....lol

I had overheating problems and after i had cleaned out the radiator and flushed out everything it was still no good and then where the hose goes into the head it was blocked. The minute it was touched by human hands the bloody thing crumbled into dust. I then had to get it drilled out and a new piece put in and since then i have not had any problems.
Cheers

"flushing" the radiator may not actually clean it out. Take it to a radiator place, get them to top and tail the rad and clean the cores out properly.

This is not something you can do at home, it is a professional job.

I had the same problem as you, replaced everything, 'flushed' the radiator with one of those bottles of stuff that claim to make it all clean and shiny again. No difference.

Took it to local radiator guy, he removed the top and bottom tanks, was cleaning out cores, but about 40% of them were blocked solid. SOLID!

So it was a recore job, now no worries! (OK, when it is going, no worries. )

Cheers

Actually , memories from the sports850 when I first got it , the wheel alignment was so bad it was scrubbing the outside edges off the tyres and the extra drag was making it overheat , how's the wheel alignment ?

Also , have you got a heap of spotlights or a splashguard blocking the grille and stopping the airflow ?

hi my daughter had the same probs with her clubman, we changed hoses water pump, had radiator re done new thermo fan. She was losing oil so the head gasket was re done. But it did not end there it still overheated! The problem the block was not flat so when then gasket was placed on it and sealed it never fully sealed correctly. Got this fixed used a cooper gasket set as they are better quality (being mon torque) and thanks to Mini classic and Hubby she is now drving like a dream.
Check the head.

Hellooo from OODLES my mini. Is being restored to be revealed in all her glory one day in the future she looks forward to meeting you all.

i think after we pull that carby apart and rebuild that... unless we go with the twins (i have on for the other side btw) and tune them properly we'll goto boc gasses and get a bottle of c02 then hook that up to a solenoid and a tempreture controller and blast c02 into the engine bay every time it gets to a pre determined temp.....

why does everyone want a Cooper S when you ca have a better Clubby

Having worked on the car and hearing it trying to start, I think probably that the wear in the dizzy is letting the timing swing. It struggled under the starter but idled very very sweetly and revved (not under load) very happily.

Its acknowledged that it has a dizzy wear problem so dont go chasing your tail until you have your new lucas electronic dizzy.

Save the energy and frustration until then

not over advanced Mike?

I firmly believe that the key to a cool mini is getting the fan as close to the radiator as possible - within .5cm is my goal
