Jeffriesa97, You fail to mention what size your engine is here but I will take you through the procedure. If your belt goes over and under the motor mount then yes you will have to remove it first. The motor will have to be supported first. Place a piece of wood on a floor jack and place it under the oil pan. Raise the jack until you see the engine come up a little. Remove the engine mount. I believe they are 15MM bolts holding it in. You may have other things attached to the mount. Remove these and set aside. Check your belt tensioner to see if it returns to it's original position before you put the new one in. If it sticks then either lubricate it or replace it. Reverse the procedure for replacement. Good luck with this.

SOURCE: can not get the serpentine belt around the motor mount

You need to remove the mount, no other way to get the belt on, Labor time is over 1 hour for someone that has done them before.

SOURCE: replacing serpentine accessory belt. Is it

From my understanding I think you have to remove the motor mount and mount the engine to remove it because I have been asking different mechanics about the serpintine belt on my 1998 Buick Lasabre.

How do you change serpatin belt on 98 buick lesabre with a 3.8 liter engine..it looks like you have to take motor mount loose?

The manual has this step in it: "remove the engine mounting bracket lower nut, stud and spacer. Carefully lower the vehicle."

It never said to raise the vehicle, so I think there is an error here.
However, it is an indication that the belt needs to slip under the motor mount.

Recommend you put a floor jack under the engine, prop it up, remove the mount stud, and lower or raise the engine as needed to get the belt out.

If you don't have a floor jack, you can accomplish the same using the car jack on the regular jack point, jacking it up, and then putting some bricks and 2 by 4s under the pan. Then let the car down until the engine touches. Take the nut off the stud and raise or lower the car as needed to open a gap for the belt to pass thru.

OK? If you have more questions, please let me know.

Change front main seal , leaking oil around timing chain cover. could be seal around harmonica balancer.

yes, I just changed one of these recently. Had to take both front and bottom off engine. Very difficult repair, as there are no good jack points for the engine when you have all the motor mounts off.
Here is procedure I would recommend.
Remove starter and engine to transmission brackets front and back.
Remove transmission starter gear cover.
drain oil and remove oil pan.
put a block under the crankshaft and jack to release weight on motor mount.
remove front motor mount (by serpentine belt)
remove belt.
remove compressor and bracket.
remove crank pulley and vib damper.
remove timing cover. mark timing belt with direction of travel
loosen tensioner gear.
remove timing belt.
remove crankshaft timing gear and key.
remove seal and oil pump housing.
clean gasket surfaces.
replace seal and reverse procedure.

If you have questions, let me know.

How to replace drive/serpentine belt for '97 buick le sabre 3.8? do u have to remove engine mount/bracket or just engine mount?

You don't have to remove the mount. Go thru the wheel well on the passenger side and remove the motor mount bolt just right of the crank pulley. Then remove the stud that the nut was on. Then remove the sleeve that the stud goes thru. Then you can change the belt.

Change belt

Not removed but part of it has to be taken apart.
It uses a special tool - Torx Socket. I have done it in just a few min - took the spacer out of the mount and put the belt on - did not have to raise the motor to reassemble!

1990 new yorker alternator replacement

You are right about removing the motor mount. You have to support the engine with a jack. Use a piece of plywood between the jack and the oil pan. Remove the motor mount and you should be able to lift the engine up about 2-3 inches with the jack. Remove the serpentine belt and then you should have enough room to remove the alternator.

Supentine belt

The motor mount needs to be removed to change the belt. The labor guide is 1.5 hours for a trained technician with experience. There is no other way, sorry for the news.

Fan Belt replacement

Sort of, look at the belt closely before you remove it to make sure the belt is not looped through the motor mount. On some makes there is a motor mount that is attached to the sidewall of the vehicle and this mount must be removed to remove and reinstall the belt, otherwise, yes it is that simple. Make sure you know how the belt goes back on. There should be a diagram under the hood for the belt routing. Or you can grab a sheet of paper and draw it yourself. If you do attempt to change it and the motor mount must be removed, you have to support the engine weight with a jack before removing the mount. Be careful and please let me know if this was helpful.
