Customer Question
My Ford F550 fitted...

My Ford F550 fitted with PowerStroke diesel engine is having issues with the turobcharger overheating and getting red hot. Can you help me diagnose this problem

Mechanic's Assistant: Have you checked the coolant? Have you checked for a leak in the cooling system?

The cooling system is good and there is no loss of coolant in the system

Mechanic's Assistant: What year is your F550?

2007

Mechanic's Assistant: Are you fixing your F550 yourself? What have you tried so far?

I have a Diesel mechanic team that works for my company, however they are at their wits end regarding this problem. We have cleaned the aftercooler, inspected the cooling system, changed both hoses to the turbocharger from the aftercooler. Cleaned the EGR valve

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

The first problem we encoutered was that the hose connected to the turbo was being blown off whilst the engine was running

Turbocharger exhaust side will get red hot under load. If the hose from turbo to the engine intake blows off, you have too much boost ! May be looking at wrong problem.??

will too much boost cause the turbo to run red hot . what should i b looking at ?
Technician: Curtis B., Technician replied 10 months ago

Turbo has waste gate , to keep it from making too much boost. Is waste gate stuck/frozen?

may b stuck ,certainly not frozen . the problem stsrted out with not getting enough boost ,changed two hose connected to the torbo that had cracks in them , thought that was the cause of loosing boost ,now i am blowing off the hose . seems i am getting back pressure
Technician: Curtis B., Technician replied 10 months ago

Waste gate is not opening. How high does boost go? Should be less than 25 inchs.

Customer reply replied 10 months ago

Technician: Curtis B., Technician replied 10 months ago
