Hi all,

After discovering a large cold patch in the middle if my large radiator when up to temp I removed them from the car to flush.
Strangely the water came out very clean.
Anyway when beeding the system I managed to loose the cap from one of the bleeding points.........."I wonder how much I need to unscrew this........fired into orbit by a powerful jet of water................"
The hose in question runs from the top of the small intercooler radiator box to the bottom of the large radiator and has a bleed point up at the intercooler end, I'm just after the bleed cap but will take the whole hose.

Next thing is the expansion tank level sender unit which turns through 90deg to fit or remove.

Amateur mechanics, don't you love em !?! And here was me considering a cylinder head gasket or engine change !?!

Any help would be most appreciated.

Cheers,

Mark.

Hi Mark,

Oops! I though I had one in my spares box - but sadly it's different. The one you're looking for looks suspiciously like a tyre valve dust cap. I don't suppose ... ?

Roy

That's the XM spares box by the way - you know the one I mean - I think you spell it ... "G A R A G E". Own up guys - you've all got (at least) one of these haven't you?

Roy

Great minds think alike?

Hi techmanagain,

Just noticed your's too! The credit goes to you however - 1) you got in first and 2) I only knew from the tip you gave me about using tyre valve extensions to make the bleeding easier.

Cheers

Roy

Thanks guys,

It is the same as a tyre valve cap.

I should have used the old adage "make sure brain is engaged before putting mouth into gear" and tried a valve cap instead of thinking it looked different and not bothering.

I cannot find bleed point #2 on Roys diagram, any ideas ?

I do not have the tool for bleed point 7 on the cylinder block, does this matter or is this the crucial one that causes hot spots around the valves.

Cheers,

Mark.

Hi Mark,

The diagram (refill_bleed_02.jpg) on page 2 here:

http://club-xm.com/forum/index.php?showto...l=coolant&st=15

No 7 is a drain plug only (as is No 1) - don't worry about it when refilling if you haven't had it out.

2, 3, 4, 5 & 6 are the ones you need to concern yourself with.

Roy

Mark,

No 2 bleed:



Lurking away at the back (centre of photo). Hence techmanagain's suggestion of a valve extension to make access easier.

It's not at all clear from the diagram.

Roy

Ok thanks for that, i'm glad you pointed out 1 and 7 are not necessary. Typically 1 is the most difficult to get to as well.

New problem - i've now got the three N/S indicators staying on constantly, ignition on or off !?! any ideas

Mark,

You'd be better moving this to the Electrical section now - before Noz gets you!

I'll have a think about your indicators - others may jump in over there.

Roy
