Thread: Puma 2.4 Alternator overrunning pulley - replace pulley or alternator?

150K seems to be about when most modern alternators fail. However I wouldn't fit a cheap chinese anything unless to get out of strife, mindful that it would probably have a short life.

YLE500310 - is the part number, you can get it in either a HELLA (made in china) or BOSCH, i have used both.
no rime or reason, some last, some dont.

the bosch you have linked to doesnt even look close.

also the cheap arse ones arent that much cheaper from what I see.

Thanks, I've ordered to correct BOSCH alternator and hopefully it will arrive in time to fit it this weekend.

I have a HAYNES workshop manual on its way as well. Can I ask if replacing the alternator on a 2.4 PUMA engine is difficult (aside from removing the fan)?

I havent done an alternator replacement video as yet..

*dis-connect battery
*remove viscous fan
*dis-connect top radiator hose and bleed line (careful not to break that rad bleed line spigot pipe)
*remove lower fan cowling.
*dis-connect intercooler hose from turbo.
*if you have the above hose bracket attached to alternator, remove it, 2 10mm nuts.
*fold intercooler hose over towards radiator out of the way.
*remove tension off serpentine belt, then remove the tensioner itself to remove both.
*3 bolts hold the alternator, a slightly cranked ratchet spanner will get them, leave the top one just finger tight
*place a block of wood/timber on top of the front diff, in that area so it will support the alternator once the bolts are all undone.
*jiggle/turn alternator so you undo the 13mm main output.
*the other plug, has a press clip on it, be careful with it as you can break the tab, give it a spray with some brake cleaner or the likes of to help ease the plug out from the alternator.
*the alternator comes out forward with the 3 bolts and the bracket, remember that you will need to assemble the bolts, bracket and the new alternator before moving into place.

reverse the above.

Fantastic - thanks so much for your detailed description of the process. I appreciate the extra tip re the screws into the cowling. I might also see if I can source a new radiator by the weekend and drop that in a the same time.

We successfully removed the old alternator only to find after trying to get the new one to fit that they were different. This is despite the interwebs saying it was compatible.

We ended up installing the old alternator back in the car and I will be searching for a correct model alternator.
