metal "tabs" bolted next to motor mount on subfram

Post by CBradio »

My subframe had some extra metal on it next to where the motor mounts go.
I don't see these parts listed on the part diagrams, I'm guessing they are there to "support" the engine in case the motor mounts fail?

Should I keep them on? Any insight into the function of these items?[/i]

Just in front of and next to the motor mounts? I think they're there in case the motor mounts get soft and tired. I had a Bav one time, same type of motor mounts and engine suspension, without those tabs, that had been hit in the front. Clearance was reduced to maybe 3/8 of an inch, possibly slightly less, but not much. Eventually if I hit the brakes hard, I could hear the fan hit the radiator. :shock: Never did any damage, but the engine moved enough with old soft mounts so contact was made.

Did they stop including these tabs for some reason?

I guess Ill leave them on.

The 2002 has something similar. On those (as far as I recall), it is a known issue that the fan can run in to the radiator, if the 'stops' are not properly adjusted or missing.
