Replacing the power steering belt on your 1985 F250 with a 351W is a pretty straightforward job. Let’s break it down into what you’ll need and the steps to get it done.

Belt Size

For a 1985 Ford F250 with the 351 Windsor engine, you’ll typically need a belt that’s around 53.5 inches in length, but this can vary slightly based on specific configurations or aftermarket setups. It’s always a good idea to double-check the belt routing sticker under the hood or consult a parts store database to confirm the exact size for your setup.

Tools and Materials

• New power steering belt
• Wrench set (usually 1/2" or 9/16" will do)
• Socket set and ratchet
• Pry bar or a long wrench (for tensioning)
• Safety gloves and goggles

Steps to Replace the Belt

1. Safety First: Ensure the engine is off and cool. Disconnect the battery to avoid any accidental starts.

2. Locate the Belt: Identify the power steering pump and the belt that drives it. The belt routing diagram under the hood can help here.

3. Loosen the Tensioner or Mount:

   • On the 351W, the power steering pump mounts are adjustable, allowing you to swing the pump to adjust tension.
   • Loosen the bolts holding the pump to release the tension. These are typically on the bracket and the bottom of the pump.

4. Remove the Old Belt:

   • Once the tension is relieved, slide the old belt off the pulleys. Take note of the routing for reinstallation.

5. Install the New Belt:

   • Route the new belt around the pulleys following the same pattern as the old one.
   • Use the pry bar or long wrench to apply pressure to the pump, swinging it to tension the belt.

6. Tighten the Bolts:

   • Once the belt has the right tension (about 1/2-inch deflection in the longest span), tighten the mounting bolts to secure the pump.

7. Check the Work:

   • Give the belt a quick check to ensure it’s seated correctly on all pulleys.
   • Reconnect the battery and start the engine. Check for any slippage or noise.

Pro Tips

• Belt Tension: Too tight can wear bearings; too loose can slip. Aim for that sweet spot with slight deflection.
• Periodic Checks: Once installed, keep an eye (and ear) on the new belt for the first few drives.

This job should be manageable within an hour or two, even for a novice. If you run into any snags or hear any unusual noises afterward, feel free to ask for more guidance. Happy wrenching!

For your 1985 F250 with a 351 Windsor, choosing the right oil and air filters is crucial to keep your engine running smoothly. Here’s what you need:

Oil Filter

For the 351W engine, the oil filter commonly used is the Motorcraft FL-1A. This is a widely used filter that fits many older Ford V8 engines, and it’s known for its reliability and efficiency.

Air Filter

The air filter for your truck can vary slightly depending on the setup, but the Motorcraft FA-1045 is a common fit for the 351W in the Bullnose era.

Tips for Replacement

Oil Filter

• Tools Needed: Oil filter wrench, drain pan, and new oil (around 5 quarts of 10W-30 is typically recommended for the 351W).
• Replacement Steps:
  1. Drain the old oil.
  2. Use the oil filter wrench to remove the old filter.
  3. Lubricate the rubber gasket on the new filter with fresh oil.
  4. Install the new filter and tighten it by hand — no need to overdo it.

Air Filter

• Tools Needed: Usually, no tools are required unless there’s a stubborn clip or bolt.
• Replacement Steps:
  1. Open the air filter housing — usually held together by clips or screws.
  2. Remove the old filter and clean out any debris in the housing.
  3. Insert the new filter, ensuring it seats properly.
  4. Re-secure the housing.

These maintenance tasks are straightforward and can noticeably improve your truck’s performance and longevity. If you have any more questions or run into any issues, feel free to reach out. Happy wrenching!

When it comes to spark plugs and plug wires for your 1985 F250 with a 351 Windsor, sticking with known, reliable brands helps ensure consistent performance and longevity. Here’s what I recommend:

Spark Plugs

Motorcraft is the original equipment manufacturer (OEM) for Ford, and their spark plugs are specifically designed to work well with Ford engines. For your 351W, the Motorcraft ASF-42C or AWSF-42C are commonly recommended options.

• Why: They are designed to handle the specific ignition requirements of Ford engines, providing reliable performance and good longevity.
• Gap: Make sure to gap them correctly. The typical gap for a 351W is around 0.044 inches, but always double-check your truck’s specific requirements.

Spark Plug Wires

Motorcraft is again a solid choice here, given their compatibility and quality. However, if you’re looking for performance upgrades, MSD or Taylor spark plug wires are also popular among enthusiasts.

• Why: Motorcraft wires ensure compatibility with minimal fuss, while MSD and Taylor offer low-resistance construction which can improve ignition performance slightly, especially in tuned engines.
• Features: Look for good insulation to resist heat and prevent interference with electronic components.

Installation Tips

• Replace Together: When swapping plugs, it’s a good idea to replace the wires simultaneously. It ensures the entire ignition system is fresh.
• Dielectric Grease: Use a bit of dielectric grease on the inside of the plug boots to make installation easier and prevent moisture ingress.
• Torque: Don’t overtighten spark plugs. Use a torque wrench if you have one — around 15-20 ft-lbs is typical for most plugs.

These upgrades should help your Bullnose start more reliably and run more efficiently. If you have further questions or need installation guidance, feel free to ask!

Switching to a FiTech fuel injection system can impact your ignition setup, but it often doesn’t require a drastic change in spark plugs or gap unless you’re pushing the engine with performance upgrades. Here’s what to consider:

Spark Plug Selection

• Stick with Quality: You can generally continue using those Motorcraft ASF-42C plugs. They’re reliable and proven to work well with Ford engines.
• Consider Heat Range: If you’ve made performance modifications that increase combustion heat (like higher compression or boost), you might need a colder plug. This would be something like an ASF-32C for a slightly colder option. However, for most stock or mild setups, the regular heat range should be fine.

Spark Plug Gap

• Injection vs. Carburetion: Fuel injection often allows for a slightly larger gap due to more efficient fuel atomization. However, the stock gap of 0.044 inches is usually adequate.
• Adjust for Performance: If you’re tweaking for a bit more performance or experiencing misfires, you might try increasing the gap slightly — but only by about 0.005 inches at a time. Just be cautious, as too large of a gap can stress the ignition system.

Additional Tips

• Ignition System: Make sure your coil and ignition components can handle any increased demands if you increase the gap.
• Monitor Performance: Pay attention to how the engine runs after making changes. Misfires or rough idle could indicate the gap is too wide.

Your FiTech system should provide a noticeable improvement in driveability and efficiency. Just remember, small adjustments can make a big difference, so keep an eye on how things run and adjust slowly. If you hit any snags or need more advice, feel free to ask!

For a 1985 Ford F250, you’ll need windshield wiper blades that are typically 18 inches in length. This size is common for the Bullnose era trucks and should give you the coverage you need for clear visibility.

Tips for Replacement

• Check Compatibility: While most 18-inch blades will fit, always double-check that they have the correct connector for your truck’s wiper arms.
• Replacement Steps:
  1. Lift the wiper arm away from the windshield.
  2. Locate the release tab or button on the wiper arm joint.
  3. Press or pull the tab to release the old blade.
  4. Attach the new blade, ensuring it clicks securely into place.

Replacing your wiper blades every 6-12 months or as needed will keep your view clear and safe, especially in inclement weather. If you need any more guidance, feel free to ask!
