I went to the auto parts store and purchased a book. I have a 1999 mountaineer that trashed the oil pump had to replace the engine, however I pulled the alternator, I am sory to tell you that if you have a 5.0 it is no easy task but the book will guide you. one bit if advice bag and label all the nuts and bolts there will be alot of them.
pull the fuse
Mine is 24 gallons.
my 2001 4.3 rwd safari gets 18-20 mpg
I have a 1998 gmc safari awd van & my pcm is located under drivers seat bolted to the floor.
Look under the alternator , as your standing , facing the front of the engine , to your left follow the belt down . It has a 3/8 square in it so you can use a ratchet to take the tension off the belt for removal. Easy to replace attached by one bolt to the engine and is sold as a unit (arm , sprng assembly and roller) for around $20.00. Just alot of stuff to reach through to get to it.
If you have enough money any conversion is possible.
That is more hassle then whats its worth. the whole front suspension is totaly diffrent then the AWD. plus the rest of the AWD equipment that is needed to make it work. if you want AWD find one that has a bad motor and replace it with the one you have as long as you don't have a lot of mileage on that motor. or rebuild the motor and there you have an AWD van. it would be cheaper than trying and less painful
In a 1997 Mercury Mountaineer : ( 4R70W )
just replace the rear brakes
Remove the cylinder had from your 1997 Chevy Astro engine. Remove the head gasket and clean the surface. Put the new head gasket on and reverse the process.
