M60 Coolant Hose Blows off of Radiator!

[632 Regal]

the M60s are self bleeding.

Is the system properly bled- this should be your first check. With your cooling system, go exactly by the book, it is mission critical after all.

you are hereby ordered to turn in your BMW immediately for failure to use blue coolant.

thank you.

I have forwarded your message to the previous owner.

The prestone antifreeze I put in:

"carefully balanced protection against temperature extremes and rust corrosion of all cooling system metals, including aluminum"

Most coolants make the claim yours does. Yes you can prbably run it for a while, probably longer that you can run plain water (especially if you are not going to stress the cooling system heavily).

However the correct Coolant **is critical** to the operation of your engine and the manual is specific about it. You ignore this at your peril. I'm not saying it is the cause to your problem at all, (but unbelievable as it seems it could be), but if your coolant was not blue when you got the car it is an indicator that whoever has been looking after or maintaining your M60 has not had BMW experience at the least, or is not up to the task.

Search the forum for head gasket/cooling system stories and in almost very case the major factor is coolant is non-genuine. BMW is not like most other cars when it comes to coolant compatibility- but like Benz and Audi and others the engine's run hotter than most and the design specs of the castings and components rely on one composition only. We know it is common to SAAB and perhaps Volvo also, but it is not to be mixed or used with anything else other than Glysantin G48 (BMW cool blue coolant).

If you still don't believe me, check this thread over on the Benz forums.

The old-hands know not ot use anything else, others that think they know better challenge them all the time as I once did. But you need the right stuff. It appears that Glysantin is almost a standard in Europe. This contrasts to the US where owners are driven to expect 'compatible' coolants will do like perhaps it does in some other cars.

Though there have been many lively discussions about this issue here, from my experience I can say that BMW may well be the pickiest of all German cars on collant type.

Phew! There we go, the quarterly coolant post is done.

Thanks Jeff, I forgot there was no bleeder on an M60. I wish mine was. Actually it is, but only so far... bah!

I understand all this......I'm not new to BMWs or their fluid requirements at all (This is one of the reasons I love BMWs, everything is made to work amazingly as long as you follow the requirements).

I'm just gathering information since I cannot perform work on my car right away in most cases. This forum is awesome compared to when I was on roadfly for my E32.

'flush green coolant to bmw blue coolant' has been in my all encompasing excel spreadsheet for this car since over 2 weeks ago

I wasn't out to patronize in any way- sorry if it sounded that way. One never knows what people know or don't know, and many new owners take a while to get with the flow on coolant, as I did. I hope you get these troubles sorted out- the temp not rising after the blow out sounds very weird Nick

It's all good, I couldn't really tell if you were or not, I myself am pissed that I can't make my E34 perfect right this very moment lol

I'll most likely be flushing the coolant in 2 weeks when I'm at home with ramps & tools

I'd expect 'superheated' coolant gas would hit the temp sensor and send your needle off the dial.
In an M60 the upper pipe is above the level of the radiator, so maybe it was really only coolant flow that was interrupted when it popped. I'd expect however for boiling to cause a real problem within seconds. Just 0.02 opinion though. nick

[Fetch]

Yeah, I have no idea why the needle never went more than a hair over where it normally sits.

As far as I can tell it works fine, from watching it warmup, to starting it when it has only half cooled down, it reads exactly how I think it should
