viscus fan !!

[mikey-t]

my car is overheating rapidly and loosing all the water so i think i have 2 problems! the fan , and a dodgy header tank cos surelly i shouldnt loose all my water!

yeh i prob shud get the head skimmed bt i did notice it at an early stage so ill see wot the condistion is when i take the head off

Trouble with second hand couplings is that they MUST be stored on their edge. If they are laid flat for any length of time they will be scrap.

yeh agreed ill be takin mine straight off a donor car if i dont buy a new one

[mikey-t]

i think i need one too! but surelly my engine cant get so hot that it looses all water in a 5 minute trip? i know there is a hair line crack in the reservoir but still! surelly the fan doesnt do that much

[JAFF]

may be your thermostat is buggerd?

why. please explain the physics!

right just brought an e30 320i and i wanted a decent project!

a project is what i have got!

it seems to run very hot when in anything other than free flowing traffic! it actually emptied the header tank in less than a minute! so i think that may be the one solution (could it be anything worse? no tell tale head gasket signs)






m8 lol....
if your fan is kaput ,coolant will expand and exit through your tank (which is leaking)
you may indeed have deeper trouble but the above need to be sorted for you to progress!
stat??????????????hmn you have said once on the move car is fine,stationary or slow it overheats-this aint related to a stat.stat would cause it to overheat all the time if it failed this way.


another thing to note once your vehicle is cold the coolant will contract and then you will introduce air into your system too....trouble on the way m8 if you dont sort the tank and coupling.

[gcorky]

The cooling fan is needed at idle and slower vehicle speeds. But a vehicle that's tooling down the road at 60 mph doesn't need a cooling fan because plenty of outside air is being forced through the radiator without the fans help. This discovery lead to the development of flex-blade cooling fans and cooling fan viscous clutches. The latter allowed the fan blades to freewheel when the extra cooling assist they provided wasn't needed. This saved some gasoline and cut down on unnecessary noise under the hood.

here ya go pepes.

blimey head source of info !! wot book you read that from

blimey head source of info !! wot book you read that from

lol ,put this up to help people understand the concept.....as today somepeople couldnt get there head round it.

[JAFF]

fairplay i had an idea but that a better way of putting it ! ill test ya now ! where can i get an m tec 2 kit ?!

[gcorky]

2 door or 4

[JAFF]

2 door m8

[gcorky]

hahaha gotcha ,hopefully got a car coming with an original kit in white?

make offer by pm if you wish.

[JAFF]

wot where you hoping to get for it

[gcorky]

sent pm m8
