First and foremost - Happy New Year to you all!

Secondly, my enquiry - I had my 300ci coolant renewed as to my thermostat and waterpump this Tuesday @ Hallmark BMW indep. specialist in Maldon Essex, and I have noticed that they did not use the BMW recommended antifreeze as it was orange in colour? Should I be concerend about this? Any input to waht one they might have used is appreciated.

I would definately get this checked out as there is quite a big difference in anti-freeze types.

Im sure this is right but if there is any bmw (blue) antifreeze left in your cooling system at all and the new stuff put in is the other type your coolant may just turn to sludge.

I would drain the coolant, flush the cooling system thoroughly with water and then refill and bleed with genuine BMW coolant.

But then again if they are a well known BMW Specialist they should know which coolant to useso you might not have a problem.

Trouble with some places is that they buy fluids in bulk rather than specifically for each vehicle (unless its a specialist vehicle). As a result they may use something thats more unviversal based but really its essential that the correct specification fluids are used.

Tahnks for the input guys, that fact that they charged me £9 xtra on the invoice to fill up the 2 gallon system does make me suspicious! Gonna phone them up tomorrow and ask - but my gut tells me that they are gonna say it's 100% safe (yeah right) they prob filled it up with tap water as well! If I decide to do it the proper way - I was thinkin of using holts radflush 2 step to reclean the coolant system. Has anyone used this?

antifreeze is antifreeze is it not?

When I did my water pump on the 540 I just bought 5 litres of generic antifreeze and threw it in.

Personally I have never heard of right and wrong antifreeze.

Actually there are different antifreeze out there - each with it's own formulations mixing them up can be detrimental to engine blocks - some can actually corrode and 'jelly up'. I think BMW formulation is ethylene glycol - phosphate and silicate free-based. I am concerend as because some OAT antifreeze may eat away on gaskets and the water pump if they are incompatible and i don't really wanna pay for other things to be replaced again if the garge has used the wong one. I'll phone them up 2mrw and keep u lot updated

This is a very valid topic of conversation and I think warrants having it's own "STICKY" thread? Perhaps in the "GUIDES" section.

Guides to using correct anti-freeze and possible effects if ignored, what do you think Ronnie???

good idea, as its one of those areas where people should be in the know as failure to use correct specification fluids can have ££££ consequences etc.

Ok - this is what they told me - "It's a premium red - we buy it in bulk - and we use tap water" Oh dear came to mind...Do I trust them or not that's the question - since all businesses try to save money - do they compromise in the quality and compatibility of products?

Perhaps included in the guide should be the effect of not using anti freeze too:eek

So did they assure you that they have supplied the correct anti freeze or did it seem they dodged the question???:shifty:

Put it this way, if I asked them if they put the right antifreeze in - they would say yes. When I asked them what exact brand - they dodged the question - "premiun red" is not a brand - more like a larger dwn ur local pub! But nevermind folks - I've made up[ my mind this morning and have been dwn to the BMW stealer and got some genuine antifreeze. I've just parked the car up and letting the engin cool dwn, and will be ramping it up for flush with holts radflush 2step and puttin gin the real-deal. Thanks for all ur help though -it's a gd forum.

So basically - if i were to jack the part 1 in your link it's behind the centre point on the 10th picture of my link - I would prefer to jack #1 if is stronger as I don't want to deform the reinforcement plate. Also - the link u gave me on the M3 link - the illustrated front centre jacking point is that pointing to the reinforcement plate or the axle plate?
