So I got the car back late yesterday afternoon and it should be ok now. They pulled the radiator, but could not find any fault. So they put it back together checking everything and making sure it's all tightened up right. They alse added Stop Leak. Guess now it's just a waiting game to see if the water level goes down. I will need a new water level sonsor though as mine is clearly not right and you can see it's very old. Any one with a spare???
I also got some new belts and thermostat for the mechie to fit while they were busy with the car. Sadly only the belt for the aircon fits, the other one is to big. Here's where it gets interesting. In my owner's handbook it says I need a 7K x 1605 and that is indeed what the new belt is. So I opened the bonnet and checked the old belt with a torch and that says 7K x 1580. First I thought that maybe they fitted the belt from the straight six somehow, but it's listed in my handbook as a 6K x 1560 for the 525i.
So now I'm trying to find out where the belt currently on my car actually came from. Will be googling some now.

It says 7PK1580 on realOEM:
http://www.realoem.com/bmw/showparts.do?model=HE98&mospid=47411&btnr=11_4838&hg=11&fg=18
Why is my owners manual saying it should be 7PK1605??? So my owner's manual is wrong? :shakehead:

Yea, but common... isn't specifying the wrong length for the belt a bit much??
And see here: http://hy-belt.en.alibaba.com/produ..._E34_530_540_E32_730_740_BMW_E38_730_740.html
EDIT: Maybe it for the older models, but then it would have been specified as such??

Please drain that stop leak sh!t out of the system.
Yes, it will block the leak and also eventually the whole system. You will after some time start experiencing overheating, failed sensors, failed seals……
They are just too lazy or cheap to repair/replace the radiator properly. A system that works properly doesn’t need that stop leak BS.

I am pretty sure the BMW coolant needs to be diluted 50:50 with distilled water. Not sure what the capacity of the system is, but i would assume something like 10L

Yeah, I have to say that is a bit too much, not sure why it would be like that.

The bleed procedure is quite simple as the M60 cooling system is self bleeding, basically you just need the expansion tank to be the highest point in the cooling system, so park it downhill or jack up the back.
Edit: Best too still read up about it just to see what issues guys have had and so on.

Hmmm, problem I noted is this:
I have seen this bleed screw mentioned on other DIY's as well, but no-one has pics and I can't seem to find it.
What I did was just to loosen the small pipe on the top passenger side of the radiator (the small one right in the corner) and filled the expansion tank till the water came out there, then fitted the pipe and continued to fill till the expansion tank is it its level.
Then I started the car with the expansion tank open. And let it run while monitoring the the temp gauge - what it seems to do is the temperature rises to just under the middle mark on the gauge, and then stays there a while. During this time you will feel the top hose of the radiator become slightly warm. Then when the temperature reaches the middle mark the thermostat starts to open and the top hose of the radiator will get hot pretty quickly. At this point you should close the expansion tank. Then the radiator should gradually get hotter from the top hose to the bottom one.
If all went well the temperature should stay in the middle.
To test I just took the car for a drive, and put the heater on, if you get hot air you can be fairly certain the water is circulating properly.
This was on the 540i that used to be auto so, things might be a bit different on the manual one (think they have different thermostats)

Just an update on the belt...
I went back to masterparts and asked for the 7kp1580 belt and they swapped the wrong one I had with the right one I asked for with no extra charge. Interestingly on their system it says that the 7kp1580 belt is for discovery from around 1994. I didn't have time during my lunch to have it fitted as well, but will see if I can get it done tomorrow.
I'm still feeling unsure about all of this, but I can only go ahead and hope all works out well.

Another update:
So had the new belt fitted. Thought about doing it myself, but as I'm going away tomorrow I thought I'll rather have someone who's done it many times before fit it for me in the hopes that it will reduce the possibility of it going wrong over the weekend. I did however stay around and kept an eye on what they did. Now there seems to be no more squeak from the engine bay while the engine is running. Result :thumb:
I also got a new water level sensor. It's a Febi part, but that should now work properly as well.

Scratch that...
Ever since I bought the car the belt would screech when I start or switch off the engine. It didn't do it always though. Sometimes I can start the car with no noise from the belt. So it's a on off thing. Recently though it started squeaking all the time. The new belt is now not squeaking while the engine is running, but it would still screech right at start up or if I switch the engine off. While at the mechie this morning it seemed fine, but just found it isn't. It does it right as the engine fires and then it's quite. Also just as the engine stops would it squeak.
So it's back to more Googling now. Sigh
