Here is the go-to site for part numbers...you will need your VIN to get the right engine mount number

I’ve got the early 1998 engine mount spare, I think

I was able to find the right part for my 99
9180961
I believe the 98 is different. I appreciate the offer!
The new one will be here on Wednesday with new bolts as well.
Time to get this one done!

Glad you were able to find it and you found there was a difference in the years.

Good luck with the removal!

Neil.

I tell you I am not sure how to get at the 11-12mm bolt that sits behind the serpentine belt pulley.
I was able to move the refrigerant pipe out of the way more but there just isn't any space to get a good wrench on it
and the pulley is in the way of a socket.
I am kind of stumped.
Can you remember what you did to get to it?
I can get you a picture of the scene tomorrow.
For now, this is a pict off ebay pointing to it.

I will have to wait until I see a picture as I can't recall. An open wrench or crowfoot cannot get access?

If you take off the lower timing belt cover , which is an M8 bolt with a 10 mm hex head, you should be able to get to that bolt at the front of car, left side of engine

I am thinking if I can wiggle the half-moon piece of the timing cover out I can get access with either a slime wrench or crow foot without removing the pulley.

I think that pipe is the fuel pipe so be careful! With the plate removed, do you have a cranked ring wrench as it may be the best option.

Those bolts will be too tight and bound in for anything other than a socket. Get good access even if you have to pull the timing belt and pulley

I had a head break off one of my exhaust manifold bolts. After fighting with it to no avail with extractors, I brought it to a local machine shop. They welded a new bolt on the stump, and along with the welding heat, it then came out easily with a wrench. If you have enough of a stud left to work with, and a friend with a welder, that might do the trick. They literally had it out in 5 min, and preserved the threads.
