When you say click over do you mean turn over with out starting or the starter just clicks rapidly when trying to start it?

Also could you remember to add the vehicle details in the thread title next time as per forum rules please, they have been done for you this time. It makes it far easier for people looking up help for their own problems.

Humm....maybe I know a 330 does need a lot of juice...but still - I'm baffled! Just exactly how long I can leave the car on ignition with the 32 c setting and low fan speed when I drain the coolant? I just bought a battery charger with boost from Halfords (ABSAAR) 12V 20AMP. I was thinkin of boosting the battery when I change the coolant, then afterwards - charge the battery. So I guess using the boost I just connect the +ve terminal to the +ve engine bay and the -ve on some metal? Also - when i get to charge the battery, do i have to take it out? Is there any considerations I have to take when I do this i.e. lost memory or does the radio need to be recoded?

You can charge the battery with it on the car and connected, and from the points in the engine bay like you say. :thumbsup

Just put the battery on charge, do the coolant change and flush, then bleed the cooling system using the points in your other thread :)

In the instructions of the manual of charger it states that maintenance battery should be charged with caution - Needs to be monitored as they are sealed and gases need to be vented - max time it can charge for is 8 hrs for these type of battery. So therefore should I continue charge it in the car or shall I remove it just to be safe?

Have you got a garage that you can charge it in? Don't leave it on the concrete floor though, make sure you put something underneath it if the floor is the only option:thumbsup

Personally i'd rather leave the battery in the car than take it in the house:eek

Ok - this is what i've done so far, I've disconnected the battery from the car and taken it inside the house and had a look @ the charge bubble window - it's black so it confirms that the battery is deeply discharged. I've just put it on the charger so in about 8 hrs or so I will inspect it again. Either the battery was on its way out - or the bimmer specialist had drained the battery/short journeys frm me, it's hard to tell. I prefer to have in the house cos the temps are way too low for it to be charged outside. The battery is lead-acid so I'm safe.

So - an update on what I'm doin, since I can't get the bloody drain bolt off the engine block, I now need to dilute out the old coolant (red) in place with the genuine BMW coolant. I will do this 4 times - allowing each time the temp to reach norm operation - so that the thermostat can release the coolant from the block. I know it's tedious - but wot can i do - I don't have the proper ratchet/extensions to take the bolt off - unless someone can do it for me b4 I start 2mrw? Can someone tell me which exact tool/extensions i need to buy for me to remove it with ease as the angle of the thing is ridiculous!

Ronnie, I can't even get a spanner in there - as it's obscured with so many things - to my knowledge, you can only get a tilted rachet adaptor there. But once u do, u don't have the leaverage to overcome the bolt's resistance...anymore help in this section would be greatly appreciated.

Well..this is odd just under 2 hrs charging time the battery charger indicates that the battery is fully charged - yet the battery indicator window still reads that the battery is discharged??? Any thoughts?

I think ur right Ronnie about a duff cell...and the looks of the battery it hasn't been changed since 2002. I know where u're gettin @ on the multimeter ;-) Anyho - it is still safe to leave it charging overnight till nxt mornin even the charger says fully charged - it's not an automatic shut off. Thanks for the help so far :)

I would just get the battery changed over if its bad dude.

I would personally recommend the Lion batteries from ECP- they are way cheaper than getting them from anywhere else, come with a 3 year warranty- we use them all the time, funny- just replaced on on a 330i 2 days ago- think it cost the customer about 45 squids for the battery- which is a great price- customer was really not sure as hew was quoted 95 squids from halfords and about 105 squids from kwik fit for a Bosch unit-

After explaining to him that we use the Lion ones all the time and that they come with a 3 year warranty ( It used to be 10 years??!! but I cant be sure if it still is or not??) but any how its at least 3 years AND that the Lion batteries roll-off the same production line as the Bosch units believe it or not- the customer's are always more than happy with us fitting them :hihi
