Where and how do you install a starter on 97 cadillac devil 4.5 hear its under the intake manifold?

The starter on a 1997 Cadillac DeVille with the 4.5L Northstar engine is not under the intake manifold. That's a common misconception for some vehicles, but not this one. It's located on the bottom of the engine, on the passenger side (right side when you're facing the engine).

To access and install the starter, you'll need to:

1. Safety First: Disconnect the negative (-) battery terminal. This is crucial to prevent electrical shocks and short circuits.

2. Access: You'll likely need to remove some components to get a clear working space. This might include:

* Lower engine splash shield: This plastic shield protects the underside of the engine. Removing it is often necessary for access.

* Possibly the exhaust manifold heat shield: Depending on how much clearance you have, you might need to remove this as well.

* Possibly the alternator: In some cases, the alternator might need to be loosened or removed for better access to the starter.

3. Remove the old starter: Once you have good access, you'll need to disconnect the electrical connections (positive and ground cables) from the starter. These are usually secured with bolts. Then, remove the starter mounting bolts. These typically hold the starter to the engine block. You may need various size sockets and wrenches. Pay attention to the location of these bolts and how they're positioned before removing them.

4. Install the new starter: Carefully align the new starter with its mounting points on the engine block. Install the mounting bolts and tighten them to the manufacturer's specifications (consult your repair manual for torque values). Reconnect the positive and ground electrical cables, ensuring they're securely fastened.

5. Reassembly: Reinstall any components you removed earlier (splash shield, heat shield, alternator).

6. Reconnecting the Battery: Reconnect the negative (-) battery terminal.

7. Test: Start the engine to confirm the starter is functioning correctly.

Important Considerations:

* Repair Manual: A factory repair manual for your specific vehicle is highly recommended. It provides detailed instructions, torque specifications, diagrams, and other essential information. You can find these online or at auto parts stores.

* Tools: You'll need a variety of hand tools including sockets, wrenches, a ratchet, and possibly a torque wrench.

* Mechanical Skill: Replacing a starter requires some mechanical aptitude. If you're not comfortable working on cars, it's best to have a qualified mechanic perform this repair.

* Parts: Ensure you purchase the correct starter for your 1997 Cadillac DeVille 4.5L Northstar engine. The wrong starter will not work.

Attempting this repair without the proper knowledge and tools can lead to damage to your vehicle or personal injury. If you are unsure about any step, please seek professional help.
