Hey guys, FNG here from Guyana, South America. I bought and imported a 2000 F150(4x4, xlt, 5.4) from the US last November. In the interests of better fuel economy, I recently did the electric radiator fan conversion, and am already seeing 19mpg, up 2 mpgs....so thanks a lot. However I do need to change the O2 sensors, as I have been having an intermittent code (P0133). I do have an exhaust leak at the manifolds, which I will try to fix this weekend, but the truck had 214,000 mile when purchased so those sensors i think also need changing. Could someone help me with the correct part # for the bank 1 sensors? I had received 2 that I'd ordered online but they turned out to be bank 2 sensors.

Thanks in advance.

 

What is the 8th digit from the end of your vin. Should be L or M. And what transmission do you have 4r100 or 4r70w.

 

Tell me more about the electric radiator fan conversion..

What do you have invested in this??

 

4r70w he doesn't have a 7700

 

How about just the 8th digit of your VIN, not from the end of the VIN, just to clarify.

 

The 8th digit is W, entire VIN is 1FTRX18W1YNB74949. Tranny is 4r70w (14 bolts on pan).
Conversion cost about 80 bucks+shipping, I bought 2 14" fans and a derale controller on amazon as a package deal and a separate flex-a-lite controller which is the one in use. It was actually easy to do, probably took about 21/2 hours with most of the time doing the wiring.
BTW, can't fix exhaust leaks..both manifolds are extremely corroded, will have to get new manifolds instead. Has anyone tried the headers from ebay?
