You may need a breaker bar for the 8mm mount to engine bolts – be very careful if you have a problem to make sure the 8mm hex bit is seated correctly in the bolt head. Clean the cross member support well before installing the new mounts. Try to keep diesel and oil from dripping on the new mounts, that's why the driver’s side dies first. Your engine will be very smooth with the new mounts and sit correctly in the engine bay.
