Thanks for your helpful advice Ed BMW. (See earlier post 1999 323i overheating). Its turned out that its not the thermostat, the coolant reservoir attached to the side of the radiator has a 'split' in it and is leaking. I thought it a simple matter of replacing it but its not that simple. I have removed all the clips and hoses I can see and tugged at it but it wont budge. I don't want to apply too much force in case I damage the radiator. Is there something I've missed? Is there a trick to removing it?

Hi, I had a similar problem with my 2001, 318 and my bet is it’s the same system.
The reservoir is attached to the radiator by the locking cir-clip, (you have probably already removed this) and a rubber o-ring seal (that you cannot see).
When you have removed the cir-clip apply constant firm pressure away from the radiator on the same plane.
Don't pull the reservoir up and down at this stage, there is a chance it will damage the radiator. Once you have loosened the o-ring seal it will move slowly and with constant pressure will come away cleanly from the radiator.
If you take to a dealer, they will tell you that BMW radiators have a problem in this area and it is better to replace both at once. This is simply not true, its because they don't take the time to remove the reservoir properly and crack or weaken the plastic housing on your radiator when they are removing the reservoir.
Hope this helps. |
