Ford Engine Id
I have a new side project starting tomorrow. Not exactly a hot rod but it does have an engine swap. 2003 Ford Explorer which I assume came with the 4.6 V8 but now has a 5.4 engine and matching transmission. Car runs okay, driving it, there are a couple of issues with what I believe are the tires and brake steering. Overall the body/interior are in very good condition. A couple of plastic pieces broken but all of the electrical functions work. Power windows, sun roof, power seats, door locks, power mirrors, etc - all good.
I understand the 5.4 came in a few different flavors so I am interested in getting an ID on the engine. Obviously the VIN is of no help so does anyone know where to find the factory markings on the 5.4s? I also have a copy of ForScan on this laptop that I use to take care of the F-350 and F-53 - that hopefully will give me some Id info too.
And yes I know about the spark plug problems these engines have - that's one of the first things I want to take a look at and get squared away. Supposedly this engine has 90k on it but I am thinking it's somewhat less. The engine was changed out by a shop and was a re-manufactured engine (Jasper maybe?) the previous owner could not pay the bill and sold to the person that I have bought the car from. He indicates that he has owned it 3 years. Info on the title tomorrow will tell me more. However putting 90k on a car in 3 years means some very serious driving. Doable for sure but that's averaging about 600 miles every week for 3 years straight. The guy has a local job close to where he lives so it's not adding up.
And I noticed that the A/C ventilation fan has 4 positions on it. 1,2,3,4. Position 1, you can hardly feel anything from the vents, 2 and 3 a little better but also about the same. 4 is all out max air. I know that 1-3 positions are inline with a resistor and 4 is not but I wonder if the resistor is about done? Or is there a blend door, vacuum issue going on - I didn't feel or notice any miss from the engine so at least up to the controller the vacuum lead should be okay. Any input?
