Subject: HEATER CORE Replacement RED ALERT - I need your tips for... Author: davidsoine : member since September, 2004 : 870 posts Posted on: 2004-09-01 10:26:44

Steering column removal (!), removing trim below steering column, loosening/removing the left IP support stanchion.

I have already removed the console - the whole front cover of the climate control must be removed, and there is no clearance to do so because of the IP support stanchions. BMW service manual says the left stanchion should be removed.

I am taking some pics of the trickier parts, and will submit them here when the job is done!

Vehicle is a 97 740iL, built May '96.

Symptoms: Strong (to me) coolant smell when the heater functions - cool mornings, and when you have the dual zone climate control set to different temps! No visible leakage.

I have been scanning our e38 forums for months in preparation for this job...seems like I'm the first one to really take it on - though I gotta believe someone else has done it.

Thanks in advance for any help you can provide on this massive job...
