4bd1t fan belt

[DODGE]

Hello All

Would anyone be able to tell me the part number for a fan belt for a 4bd1t ?
I would have had it matched but it is laying on the road somewhere.:angel:
Thanks Gary

G'day Gary, The standard Isuzu part number is 1136713400. If your motor is a standard unmolested one that should be the one. Another number I have here is BX45 (aftermarket number I think). Hope this helps.

I've got my spare on front of me and its a 15A1185.
I got it from my local Jap truck spared place and I'm sure I asked him for the belt for 4BD1T ( mine was a NA stage1 engine and it definitely fits that).

They are 'B' section belts.

Now part number BX45, is suspiciously like 'B' section x 45 inches length.

And 15A1185, could be 15mm wide x 1185 mm length.

45 inches = 1143 mm
1185 mm = 46.65 inch

So those lengths are probably close enough that either might fit with the adjustment available at the alternator. Just my guessing though.
