I'm talking about the ones that fasten the fan and pulley to the waterpump. I bought 5/16ths bolts, but they are too big. Or maybe they are coarse, and the threads are fine. I don't know. Does anyone else know? It's a 4.3 with a short neck water pump.

Should be 5/16" fine thread.

I got 'em. M8.0x1.25. Thanks though. :)
