- Mini cooper water pump Kaputt
The wifes Mini cooper s has developed a cooling problem
not frozen up
over heats very quickly but the rad is cold and the heater blows cold
so by my logic it could be the waterpump , all belts are fine and every thing is spinning round .
How easy a job is replacing the pump as I have no work at the moment and so dont want to pay garage prices when I am a bit skint.Posted 8 years agojustmeMember
what a load of utter bollocksPosted 8 years ago
on the new minis theres an important part of the water pump thats made of plastic and after they have been stood (sometimes only for a couple of weeks) it hardens and when you start it it breaks causing said problem – mini know of this fault and the replacements are now made of brass
the reason I know this is because it happened recently to my daughters just after she bought it ie when it had been stood. because it was going into the main dealers to be done I took the car to a local garage that i use and who is honest to find out what needed doing so that she wouldnt get bulled by the garage
if its not a new mini troutie ignore this
hora where the f do you get your imfo from why the f would bmw use a peugot engine???
trout if you want to ring me mark (montylikesbeer) has my number
The new mini does use an engine partly developed with Puggyeot. The Cooper S uses a 1.6 twin scroll turbo engine as used in the new Pug GTI. Why would BMW develop a new 1.6 engine for just one model ie mini when most of there engines are large capacity inline motors rear wheel drive. I believe the bollocks are on you.Posted 8 years ago
Another reason to avoid main mini dealers- boss had an accident and needed a new alloy, arch trim and tyre. The parts dept said atthe time -'no probs we can get the alloy in next day etc' ..two weeks later the car was ready to collect.
Why? They also provided a courtesy car and the bill to her insurance company for the courtesy car hire (another minging new shape mini)….£2,000.
Previously they had asked her for £1,300 for a new electric motor sensor for the convertible roof when it failed.
Wonder why main dealers are called stealers sometimes.. 🙄
justme- I've owned a 54plate Cooper. Its a rough and agricultural engine IMO. Any decent garage should be able to work on it outside the Mini warranty period.Posted 8 years agoivantateMember
1st gen MINI had a Chrysler engine which was unrefined, uncharacterful and uneconomical. Fitted purely on cost grounds because of the spend on the rest of the car.
Diesels used the horribly underpowered Toyota Yaris 1.4 engine.
2nd gen MINI use the 1400 and 1600 codeveloped with PeugeotCitroen which is a great engine, very advanced/powerful/clean for size and economical.
2nd gen Diesels use the Ford/Peugeot/Citroen 1600 HDI/TCDI engine which is also a good economical and clean engine.
Latest rumour is that 3rd gen with be sharing the whole front structure with Peugeot/Citroen.
JustMe, ???????????????????? I though everyone knew the MINI had a skanky engine.Posted 8 years ago
Its an 05 with 22000 on the clock bought when we had disposable income
its fate from here on in is to be
bodgedRepaired as cheaply as possibly and traded in for something more comfortable / more economical / .
mrs trout still wants a mini though whats the diesels likePosted 8 years ago
trout- if shes going for the first gen still (on cost grounds) then the diesel (Yaris engine) will still be alot as they command a premium?
I reckon get the thermostat changed and keep it as it'd probably cost you a grand or two ontop and you'd end up with essentially the same car but with unknown foibles.
Plus the difference in mpg/cost wouldnt be enough to cancel out the additional £ outlay?
Why not look at something else entirely different? Quirky and small?Posted 8 years ago
Im inclined to think its the pump based on what you've said so far.Posted 8 years ago
Usually the heater matrix is fed from the main engine cooling circuit and not the rad cooling circuit (this could be tosh as i dont know minis per-se), so if the heater remains cold, suggests there is no water circulating round the engine.
The thermostat is worth a look first if its easy to get at, just take it out of the housing, replace the housing and then run it up. If its the pump, the rad should remain cold, if its the thermostat then the rad should heat up.
Hope for you its the 'stat for ease of replacement and cost.coffeekingMember
I'd try the stat first, but without seeing the cooling circuit I'd say it is odd to have the heater matrix fed by the stat-controlled feed. Normally the heater matrix is on a permanently open (or valved at the heater controls) circuit around the engine, providing a) secondary cooling and b) warmth before the stat opens.
water pump thats made of plastic and after they have been stood (sometimes only for a couple of weeks) it hardens
While I'm sure the part might be at fault, I'd bet my bottom dollar that there isn't a single part on the car that's made of plastic that "hardens" through lack of use – they sit un-used on the production line for weeks, then weeks in the dealers/shipping containers.
Just realised I'd duplicated bigyinns post pretty much, sorry!Posted 8 years agojustmeMember
sorry folks but until ive asked someone who i know and believe I'll stick to my original statement if I'm wrong then I'll apologiesPosted 8 years ago
troutie no idea what they cost it was replaced on warranty. hers is a 6mth old diesal and it seems nice -she likes it in preference to her previous car (an mx5) also averages 54+ to the gallon
wheres justme now? -at work much as i try to avoid it sometimes i have to do it and my work does involve a computer screen gfergusdMember
Very likely the water pump impeller has failed . . . heater coolant supply on most modern engines forms part of the thermostat bypass loop which will always be hot if coolant is circulating . . . jammed closed thermostat makes no sense whatsoever based on rapid overheating AND no heater . . .Posted 8 years agoNon Stop NunMember
It could be a air block , if i remember there is two cross hesded screws on the rubber pipe leading from the coolant res to the radiator try undoing these as you top up the coolant with the engine runing .Posted 8 years ago
I was told its a common fault with mini coppers . mine was a 05 plate as well and i had a bit of luck that a local garage knew what it was and it took him 5 minutes and did it free of charge for me.
