Hello everybody I have a mack granite 2004, 460 hp, dump truck, lately I have a power loss on freeway, what happens is engine oil temperature goes up to 210, 220f and power loss occurs, I took it to the local dilership they chuck the turbo, air to air, fuel pump, compression, they couldnt find anyhing. Before oil temperature never went over 200F.

It's OK for the oil temp to get as high as 250 with no effect on power. Mack has a service bulletin on this. Is fan clutch stayin on all the time?

No clutch fan is not staying on all the time but it comes on more offten and when i start the truck in the morning the chutch fan kicks in but i guess that normal
