1998 NISSAN TOOK STARTER OFF AND TRY TO REPLACE. NEW ONE CAME WITH HOUSING. HOW DO I GET OLD ONE OFF. HOW MANY BOLTS DOES IT HAVE?

The starter is located where the engine and transmission bolt together. it would be near the drivers side of the engine in front near radiator, not the fire wall, bottom of engine. you have to replace it from under the car. make sure you disconnect the battery first. 2 bolts mount the starter to the engine. the bolts go straight up through the starter housing into the engine block. wires from the battery and start signal wire are mounted on the starter solenoid. they must go back on the proper connection on the new starter. Some new starters come with 3 terminals for wire connections. make sure if your old starter has only 2 connections and the new starter has 3 you connect the small wire to the small terminal marked by an S on the solonoid.

o remove:Disconnect battery negative lead.Disconnect positive lead and connector of starter relay.
Remove three fixing bolts from starter motor. Top bolt also holds the cable support.Slide starter motor to rear, turn and lift upwards.To reinstall:Transfer locating bush to new starter motor.
Reinstall in reverse order.Torque bolts to 50nm.

try moving the starter up and to the front, the nose of the starter should clear the bell housing

1) Disconnect Negative Cable on Battery
2) Starters on right-side Close to Trans. Bell Housing
3) Remove the 2-Starter Bolts and Shim if it's
if it has shims.
4) Remove the wires off Solenoid: Mark Them:
5) Remove the Heat Gaurd Over top of Starter:
6) Take Starter on Out.

To Re-Install Reverse the Procedure that you Removed the Starter. NOTE: the Shims if there was any are only nessary if the Casting of the Starter is not Exactly or Close to The Original.

Be sure that All the Wires you Took off the Starter Solenoid are put Back on the Exact Same Terminal. And Snug them up .Be careful not to Over Tighten,:
Specs on Bolts Are :
Torque Starter Battery Cable Nut to 90 inch lbs
Torque Smaller ingnition wier nuts to 18 Inch Lbs
Torque the 2- Starter Mounting Bolts to 35 FOOT lbs.
Remember if your Old Starter Had Shims the New one MIGHT need Shims.All Starters Casting are just a Little Different. like by thousands of an inch. So if you have problems you might have to remove or add shims,they come in different sizes. Hope this has helped you,Please let me know how this solution Helped. Thank You: From d_hubbs

Yes I would for the starters design is totally different so problems will occur

• Open the hood and locate the starter attached to the transmission bell housing. To inspect and remove the starter, it may be necessary to work under the vehicle. Park the vehicle on a solid level surface and set the parking brake. If the vehicle needs to be lifted, support it with jack stands.
• Disconnect the negative battery cable, wrap the cable end with a shop towel and place it away from the battery post.
• Mark the starter electrical wires for installation reference. Remove the starter wires.
• Remove the starter mounting bolts. Remove the starter.
• Compare the new starter with the old one to verify that you have the correct part.
• Using a flashlight, inspect the flywheel teeth (through the opening in the bell housing) while an assistant turns the engine over by hand. You should replace the flywheel if any teeth are missing, cracked, or chipped.
• Install the new starter. Torque the mounting bolts to the manufacturer's specifications.
• Attach the electrical wires to the new starter.
• Reconnect the negative battery cable.
• Start the vehicle to verify the repair.

The starter is bolted to the bell housing.
Is has a positive cable from starter solenoid.

1. Remove the negative battery cable at the battery.
2. remove the power cable from the starter.
3. remove the starter mounting bolts (typically only 2 bolts)
4. Install new starter. Hand tighten mounting bolts
5. Secure both bolts to about 35 Lbs of torque
6. Connect power cable.
7. Connect the negative battery cable at the battery.
8. Test (start the car).

remove negative on battery starter is on side of motor remove wires(make note of were wires go use colored tye wraps or number masking tape to identify.remove starter mounting bolts install new starter install wires exactly how they came off old starter secure everything make sure its all tight!hook up negative on battery start vehicle!!!!

First locate your stater on your truck. Take the two bolts holding it on off, remove old starter, replace with new (taking care to watch how old one comes off) put new one in the same way old came off tighten two bolts holding it secure.

Wow it sounds like that they are not shiming the starter. On general motors products a new starter has to be shimmed, so that it lines up correctly with the flywheel. This is what is causing the flywheel/starter bolts to break and the noise you are hearing. Its not a hard process, just time consuming probably why it has not been done.
Sorry. Good luck! Dont forget to rate. Thanks, James
