What size belt would you need if by-pass the smog pump on a 1993 ford f150 5.0 liter?

You can't definitively say what size belt you'll need for a 1993 Ford F-150 5.0L after removing the smog pump without knowing the specific accessories you have on your truck (e.g., power steering, air conditioning). The belt routing changes significantly when you remove the smog pump, altering the overall length needed.

To find the correct belt size:

1. Consult a Belt Routing Diagram: Find a diagram specific to your 1993 F-150 5.0L *without* the smog pump. This is crucial. Some auto parts stores might have these, or you can search online forums dedicated to Ford trucks. The diagram will show the new belt path and usually list the correct size.

2. Measure the Old Belt: If you've already removed the smog pump and the old belt, carefully measure its length. This provides a good starting point, but be aware that it's not always perfectly accurate.

3. Visit an Auto Parts Store: Take your truck (or at least the old belt) to an auto parts store. They have tools that can measure the belt length needed based on your existing pulleys and the modified routing. This is the best option for accuracy.

Caution: Removing the smog pump might trigger a check engine light, and it could be illegal in your area. Check your local emission regulations before making this modification.
