    Hi, I'm just a little bit confused here. According to Detroit reference from that document see attachment it says fixed pump belt is 9mm longer then variable pump belt. So did you want to say it is too short not too long right? Meaning I still technically can ran my own belt from variable pump on the fixed one? Just wondering I'm not trying to be a smart a.s. and yha thanks a lot with DDDL pictures Im swapping it on my engine tomorrow. So far changed all on the software side , disconnected and ran for a few miles,it works. Got the fixed pump today. But forgot about the belt. And the outer diameter of a pulley is the same too. I just don't really understand the point with the belt Screenshot_20221206-205940.png Screenshot_20221206-205940.png

    According r parts department the parts number is different for the manual vs termo clutch unit. Thermo clutch belt too loose on the manual set up. Use the belt from the manual configuration and u save some future headache.

    Hi all, I'm trying to figure out where to change coolant temp in my dddl to kik in engine fan before 225F. I changed in cpc to 210F under PGR006 Fan coolant temp stage 1. But it doesn't help. Is there other location I need it to change?
