Any of you know Mack mechanic shop around Raleigh NC ?Local dealer I went is not good .Thanks for your help.

Yes it is Dealer I bought it from did not know, they just made up the letters . LOL . It is CV713 for sure , engine is AI 375 because has RD 4500 Alisson Tranny

Dealer did not turned up the idle since there was no code, I am thinking that they should able to tell me the fan is normal for the model, after all they had all the info and vin # etc . Instead they change the solenoid with new one .my old one was working just the way new one did ????? It is all about taking advantage from the owner of the truck.

Today I went to Mack dealer, They hooked up to computer,no codes still running rough,change the solenoid for fan, did not stop the fan after $ 396.00 they told me it may have some air in the fuel system ,drive it few days and see what it does? Also they told me that my fan, designed to run all the time no free spool!!! why they did not tell me that before changing my solenoid? Does anybody have 375AI engine in granite to see if the fan stays all the time? Thanks

Air,checked solenoid it works fan hub moves in and out but it will not disengage. I will check the AC switch today???

No just oil ,filter change, grease

forget the point out that, Fan stays on all the time and there is no switch on the dash to over ride????

HEY friends, I took in my truck to Mack dealer for PM, before the PM it was Idling fine after PM It is Idling really rough and not more than 500RPM. under load it runs fine. Before I left the dealer I didn't realize the problem. Any help? Thanks Also fan stays on all the time,no fan switch on the dash?????

I am not an expert but I have friend has new granite .he was working on his radio and he had plastic cover top of the dashboard open.He told me all fuses are there. I hope it is some help.

As soon as I figure out how to post pictures .I will add them. Any help how to do it?

Hey you all , I made it home safely,after close inspection (as above mentioned by you all) I am not satisfied, brakes are all needs real attention, AC belt needs to be change .I will do both. Total grease job and fluid, filter change in order. other than that I am happy sailor. I DO HAVE ONE QUESTION, there is a regular gate valve (like you will have in your house plumbing) above the rear valve cover looks like part of heat system.. ANY IDEA what this is or just first owner installed it for some reason? Thanks

Hey friends, I just picked up my truck 2005 granite dump from Oak City ,WI and I am on my way back to NC. Everything checked out good ,it drives very good (with out any load)will see ,ones I load. There is a Indication lite come on the dash, inside of the info center, it looks like a Lightining bolt or look like Z any Idea what it is? Should I be worry? Thanks again.

Thank you All

Hey J Hancock this is my first mack,I am going to drive home about 1000 miles or so ,is there anything( other than oil, coolant and brakes) I should check it out before the trip.

Hey Friends What is the use for the front bumper guard. Does it have a special purpose or just for the looks, I don't like the way it looks, thinking to take it off. Unless it helps for air flow for the radiator. Thanks for your help
