My turbo is starting to make alot of crazy noise, It is on a 2006 400 aset. Mack says they want 4100.00 for a reman. Anybody got any ideas to get out of the Mack price, and get a better deal.Who does Mack use for turbos

The new thermostats did the job

Can any one tell me if I am correct, I am removing turbo and everything to install an injector control in the side of the engine,on number 4 , do I just unbolt the old one and stick the new one in, shouldnt be any timing involved is there or adjustments? I been getting 8 - 4 codes.

Thanks everyone, I will replace the thermostats, and start with that

I have a 2006 aset 400hp in a 2007 truck Vision. The water temp runs about 140 driving, it will climb to 200 on a hill, and the fan will work properly when needed, Can it be my thermostats are stuck open, when I idle in cold weather, it gets down to blowing cold air in the cab heater
