I want to replace my serpentine belt. (Called out as a "Drive Belt" on Ford Parts.Com) Apparently, there are 2 different Motorcraft part #'s for my truck's configuration. I have the build sheet for my VIN and it shows no "cold weather package". I do have California Emissions Package and a Block Heater. (Maybe the block heater is the cold weather package??)
These are the 2 choices:
Motorcraft # JK8-1227
7.3L; Single alternator; Without cold weather package.
Motorcraft # JK8-1223-AA
7.3L; Single alternator; With cold weather package.
I was wondering if someone has the same truck I do and knows the correct Motorcraft part #, thanks.
As I side note, I hate how Ford Parts.Com has you enter your VIN to make sure you get the right part, but then the search results still show you parts for every different engine and option. You would think that the search results would be directly tied to the VIN!!!
If anyone has a better source for accurate parts, I'm all ears too.
Per my knowledge the only difference regarding Serpentine Belt size is whether you have one or two alternators. I replaced my Serpentine Belt with a new Napa P/N: NBH25081223HD (Gates Micro-V VK081223HD Green Stripe FleetRunner) heavy duty 8 rib Serpentine Belt. At the same time I replaced the Top Radiator Hose with a new NAPA P/N 066 Rerouted Curved Hose ( 6A31 EBP 80MH70 ZDS 0143) (For 2 Alternators Kit) that allows the Serpentine Belt to be changed without removing the Top Hose. I saved my original Motorcraft Serpentine Belt which was in good serviceable condition and be kept it as a spare.
I have not seen any information on why the "Cold Weather Package" changes the belt, but I imagine it has something to do with the alternator pulley size. I do know that if you put the longer 122.7" belt on in lieu of the 122.3" belt it will work, but you will get strange sounds from the belt as is is not tensioned properly. It will vibrate at idle from the alternator down to the PS pump.
