I need the Napa numbers for the 4.3
(year 2019)

Cap
Rotor
Fuel filter

I called PSI today but they gave me only their numbers and my guy at Napa had no luck cross referencing.

Thanks!
 
Sorry I didn’t get these back to you. Buzz isn’t a high priority for me right now
rotor RR256
cap RR253
we just changed the fuel filter the other day and didn’t get the number. It’s a ford filter though...... I know doesn’t make sense but it is. I’m headed out to the shop Sunday.... I’ll try to remember

No problem at all. Actually my mechanic got the numbers and got everything installed

Runs great but the check engine light is on now. Any thoughts on this??
Maybe I need the software??
 
There is a way to get the code off my ‘16. PSI walked me through it while I was waiting for my software to show up.
I’ll try to explain it;

next to the ecu there is a white electrical connector with a dust cap (believe it’s on the left side)
take the cap off and you will see I believe 8 or 10 pins (where it connects)
with the tab at 12 noon (top) put a jumper wire between the top left and top right pins (key off)
go to the control panel with paper and pen ready and turn the key to the on position (do not start)
the engine light will blink a code 3 times. The code should be 1 6 5 4. Any codes after that will be the engine problem codes. And it will blink each one three times in a row.
if you message me an email I will send you the service manual they sent me with all the codes.... or I may have uploaded it somewhere here but I’m not sure. It’s big!

ps be careful with the cap and rotor replacements. The distributor is plastic and very easy to cross thread the screws (also take the thread locking compound off of them, it doesn’t work well with plastic). If by chance you loose the threads a longer sheet metal screw works to get you back going again. :X3:

just sent you my email.
How much does the software cost??

thanks again!!
 
The belt slipped off the tensioner pully. That is what caused the check engine light to come on.
Somethings seems to be out of alignment causing the belt to shred on the side then wonder off
 
Wonder if it’s just an alternator code then? Or an overheat code if it ran without water circulating for a few minutes. Only things that can be out of line is the tensioner and the alternator I believe.
 
The temp was normal when the check engine light came on. Probably because we only ran it for very short intervals that day.

Both the old and new belt had lost one whole “v” groove. Made the belt narrow but because the wear appeared to be so even we didn’t notice it at first.

Nothing appears to be out of alignment yet
Time will tell I guess

Got 4 hours on the new belt. No sign of abnormal wear.

Can’t figure out what happened to the other two belts. Oh well

Not installed properly maybe??? It can be tough to make sure every grove is right on every pulley. Either way time will tell. If the code is still there disconnect the battery and clear it. If it comes back then it’s a diagnostic thing. Just gotta keep after it to figure it out! I still got a gremlin buried in my machine somewhere. Hasn’t showed itself for about a year but when it does it’s a nasty nasty! Can’t even turn the key on without serious issues. And by the time I get it to a tech it seems to have resolved itself :muyenojado: It’s happened twice and we haven’t gotten close either time to figuring out where he‘s hiding.
