2012 Ram - Alternator and Oil Cooler

[Mopar1973Man]

I got a phone call from a guy I've done work for in the past (injectors and dual disc clutch). Call me up and lets me know that why he past me like I was standing still last night. He was coming from McCall, ID and already had the dash chiming at him for low battery voltage. The alternator failed he made it close to my place about 5 miles south of home. I went down snatched the batteries out brought them to the shop and used the big battery charger on them for an hour a piece at 40 Amps. Asked a friend to give me a ride back so I could install the batteries and get the truck to my house. No problem started up and got it moving down the pavement. 

 

Simple fix just get a fresh alternator and while I've got the truck I'm suppose to do a oil cooler gasket being he's leaking lots of coolant around the gasket.

Just found out NAPA has a selection of different re-manufactured alternators. There is a 160 Amp, 180 Amp and one more. The 160 Amp is just about 200 for price. There is options for you guys to have bigger alternators but I'm not sure what the fusible link rating is and if you have to update it for the 4th gens.

Was his 136A stock?

 

i can’t recall if it was ‘10 or ‘13 that the base alternator went to 180, with a 220 option.

Stock is the 160A alternator according to NAPA.

Finished project. For the most part. Gotta do one small task for the owner and fix his OBDII port which is complete damaged. I do have the pin assignments for the plug once again.
