bennno2005 Posted February 22, 2016 Report Share Posted February 22, 2016 What coolant goes in an E46? Am I best getting from BMW? I checked mine at the weekend, says its only good down to -7 and is clear so looks just like water to me. How much will I need? Its a 330CI BTW.

TriggerFish Posted February 22, 2016 Report Share Posted February 22, 2016 I've always used BMW stuff in my E46. For the E30, I've got some Comma Xstream g48 (I think), that's meant to be compatible with the BMW stuff, and is a fraction of the price. I'd check it's compatible with the e46 coolant, but I think it's all interchangeable. Link to comment Share on other sites More sharing options...

Looking online I'll need about 9 litres. Link to comment Share on other sites More sharing options...
TriggerFish Posted February 22, 2016 Report Share Posted February 22, 2016 I want to say £7.50 or £15 for a 1.5l bottle. I can't remember exactly, but it was a lot more than the Comma stuff by the time you've got the concentration correct. Link to comment Share on other sites More sharing options...

Figure I'm best getting it sorted sooner rather than later. Link to comment Share on other sites More sharing options...
Silver Streek Posted February 22, 2016 Report Share Posted February 22, 2016 The Comma G48 stuff I think is the same as BMW use, they just charge you a shed load more for it. Basically whatever you use has to be glycol based not the acidic OAT stuff that's usually coloured red. Glycol based stuff is generally blue. I bought a 5 litre tub of glycol based coolant from ECP when I was picking up and new rad for mine last week, it was about £16 or £19 for 5 litres of concentrate. Was the right spec for E46.

bennno2005 Posted February 24, 2016 Author Report Share Posted February 24, 2016 Thanks for the replies chaps. I've ordered BMW stuff, they gave me trade price so it cost just shy of £32 for 4.5l plus a washer for the engine block drain plug washer. Only about £8 more than the comma stuff. Worryingly I don't think my car has any coolant in it - its clear and looks like water, plus the tester said its only good down to -7! Link to comment Share on other sites More sharing options...
