Question about 1999 Pontiac Grand Am GT
How do i change the motor 2.4
It is simple actually.
Just time connsuming.
First you need ot know, you have to pull the motor and transmission.
you need to unplug every thing, formt he motor and transmission, and thing that will tie it to the car.
Electrical cables, wires fuel lines, and transmission lines.
Pull each front tire off, you will need a drive axle removel tool and a ball joint seperator, youy can rent these at autozone. It is called loan a tool, you pay for them then get themoney back when you return it.
you want to remove the center axle bolt, this will be tough, best way is to use a ling pipe like a jack handle to turn it off.
then you need to undo the bolt for the ball joint and the tie rod ends, use the seprator with a hammer to remove.
use a large pry bar for the ball joint and push down on the control arm to pop the ball joint out and away form the arm.
Once you get it out, turn the entire assembly outward, the strut will turn with it so don't freak out.
then pull the assembly out tword you so that the drive axle pops out, then grab the axle and pull it out of the trans. Once you get both out, then move onto the motor mounts.
there is three of them, one on the passenger side on top one on the drivers side on bottom, and then the trans mount attached to the trans underneath.
ok not ur ready, using a cherry picker (engine hoist) attach the chain to the loop mounted on the top of the motor, ussually placed around the intake and heads. lift your engine out.
remove all of the bolts form the transmission bell housing,that is the big part attached ot the motor, you can then simply pull the transmission off of the motor. Make sure you do this on the ground to make sure you don't drop the transmission.
to put the trans oon the new motor, slide the gear into the trans attached ot the trans, do not remove the gear. you will have to wiggle the trans back and forth up and down and turn it a bit to get it to slide in, as the gear needs to line up with the sline. Replace the bolts and your ready.
Put your new motor in and put every thing back in the same order you took it out, as this will ensure you don't miss any thing.
If you have any problems or any questions, just message me back an i will be glad to help.

seems like your oil pressure switch gave up, its located on the side of the oil filter, you can take it out and test with a amp meter. it should cost you less than 20 bucks to buy something like that.

If it was the same wiring and engine it should fit if it was an SE and the original was not it may not and you wont be able to make it but you may be able to have a mechanic get it to work this would be hard to fix here.
