Can some one tell me how to remove the pressure from the hydraulic tensioner on an E46 to replace the drive belt? I have over 25 years experience as a shade tree mechanic, but I haven't tackled one of these yet. Thanks for the help!
The BMW TIS says that you remove the dust cap from the tensioner pulley and use a socket/wrench on the bolt to push down on the hydraulic tensioner just enough to release the belt. Installation is the reverse. If I recall correctly, this is the procedure I followed when doing my E36 and it worked out well. Matt
Thanks for the direction. I thought that was the answer, but wanted another opinion. The Bently Manual falls short on the subject. They only show how to do the mechanical one. Dave
