330ci 2003 Hi all, Couple weeks ago I noticed the low coolant light. I bled the system and topped it up.. probably half a litre. Today I had the same light, expansion tank is almost empty.. havent topped it yet. There is pressure on the rad hoses.. I checked the oil cap and its not...

I'm trying to remove the cap on the hydraulic tensioner pulley so I can de-tension the belt to get at the water pump. I searched, but didn't see anything directly related to removing the cap.. just 'remove the cap'. http://forum.e46fanatics.com/attachment.php?attachmentid=408950&d=1310166474...

Ok guys, so here is the deal... I am new to this forum and to the Bimmer world Just bought a 2000 328i a week ago and the stupid service engine soon light came on yesterday... I want to go with the cheapest solution... buying a brand new OEM gas tank cap... but I would like to kind of know mine...
