There are quite a few reasons the engine could overheat other then a failed cooling fan clutch. I wonder if the fan is always on because the engine is always running hot?
This condition may be caused by any of the following possibilities:
• Installation of an aftermarket grille.
• A plugged charge air cooler.
• Fan clutch not operating properly.
• Drive belt slip.
• An overfilled transmission.
• Turbocharger not operating properly.
• A plugged air filter

Hope that helps........

Duramax diesel


most likely a bad injector, you need to check balance rates for the injectors with a scanner. if the rates are farly equal then it is probably a rod bearing but injectors are a common problem that's why they changed the original LB7 duramax(2000-2004) from internal injectors to external so they would be easyer to change.

WHERE IS THE FUEL RAIL SENSOR LOCATED ON A 2004 CHEVY 5500 DURAMAX ENGINE


If you are looking at the motor. follow your supply lines that are on the drivers side up. they will go into a juction box under the wiring harness about half way up the intake. your sensor is just before the box. What is you duramax doing? They are prone to injector and injector cup problems. Feel free to call me 570-878-5222. leave me a message if needed.

My 04' Chevy 5500 truck with 6.6 ltr. duramax lost power twice while climbing the highway in the Yukon territory. Pulled off the side of the road at idle, throttle would not take engine past 2000


Did the check engine light come on ?
Could have been a restriction in the fuel line or a problem with the throttle position sensor among other things.

My 2004 chevy silverado duramax speedamoter is not working right, sometimes it don't move other times it goes to 120mph


I had that problem on my 01 Sierra, Lithia said it was the ignition switch, 500 dollars later it wasnt the ignition switch. I traced my problem to a loose wire on the main fuse box under the hood. It connected only sometimes which caused my guages to snap around. Hope this helps.
