Should engine mount bolts be replaced when changing the timing belt?

Hello everyone,
I'm currently in the process of replacing the timing belt on my PD ASZ engine in my Golf 4. A question has arisen: do the 7 screws for the engine mount need to be replaced, or can the old ones be reused without any problems? Neither of the guides here on the forum mention replacing the screws for the engine mount. When you search online, you'll find reports of stripped screws on the engine block when reusing old ones.

What are your opinions or experiences regarding this?

Thank you and best regards.

We always replace the screws as well (it affects the price of the timing belt kit).
(which doesn't really matter anymore). Whether it's really necessary... that's a good question, but...
You sleep more soundly.
My Octavia (which has a detached engine mount) was probably damaged by...
The flexible corrugated pipe inside the trouser leg was torn, rendering it unusable.
It ensured that the path of the 'top' block was limited.
-> The bearing started to loosen and then eventually broke.

Best regards,
Micha

Okay, so I've always had the timing belt changed. After my Polo was once in the workshop for a different issue, and the mechanics were working on it, the threads stripped during the next timing belt replacement. Okay, very important: No impact wrench, pay attention to the torque, and possibly use new screws.

I would like to work there as a RLF. If it doesn't explicitly state that the screws need to be replaced, they can be reused.
"On my Audi 80, I've always used these 'standard' screws, for example, the screws for the torque strut, transmission, engine mounts, vibration dampers, etc."

According to RLF, they are supposed to be replaced.
Tighten the fasteners with torque plus an angle, in a specified sequence.

Then you'll be on the safe side.
I have repeatedly used the screws mentioned when working on the ASZ golf clubs. Starting properly and paying attention to the torque has always worked well.

Hello everyone,
I have now obtained new screws and have partially installed them. However, I'm a bit concerned because the screw heads that attach the bearing to the motor mount are not aligned with the edge as specified. The screw towards the splash guard is okay, but the one in front of it is about 4mm away from the edge. During the last timing belt replacement, which was done by a dealership, it was tightened like this (you can see the marks), but it's actually not correct. Should I tighten it again in the same way, or should I loosen the transmission mount and properly align it? Can it really be that simple, since I don't want to screw the motor in while it's under tension?

Thank you and best regards.

I would like to relieve some of the stress on the motor from below. Loosen the brackets and then screw the bracket "sideways" in a stress-free, parallel position to the motor mount, so that the motor mount itself is not already twisted or strained internally.

I have never used new screws in all these years. But that's a matter of belief or personal preference.

Hello Autoservice,
But I'm replacing both engine mounts, right? (or: both the left and right engine mounts?) I also have an engine stand to hold the engine, or would it be better to support it from below?

If nothing has been screwed or changed on the transmission side, then what's the point?

I would only align the right engine mount.

What exactly isn't working? I didn't understand that.

The easiest way, as described, is to slightly lift the motor from below, align the bearing parallel, and tighten it securely. It has worked every time so far (but I've only done it four times...thank God I don't have to do this kind of thing professionally ).
