Hello all you 6.0 owners. I have a 2003 F 350 6.0 . I have been reading alot of posts/threads on egr delete and this is something I really want to do to my truck because I think it cant be a good thing pumping exhaust back through the engine. The theory behind the delete all makes perfect sense to me and it all seems like positive results in the end except for one thing that I cant get a definite answer out of all the reading that I have been doing, will the coolant fan work after the delete or not. Some say that they just put the egr valve in and plug it up and the valve no longer is functional but they plug it in. Some use the block off plate. I have read the info about how this disables the fan and Im trying to find out how to handle this. I want to do the delete but I want my fan operational also. Thanks for all the valuable info and keep up the good work.

 

humm i have never heard or thought of this i have did a egr delete and have not noiticed my fans on but it has been relly cold so my fans will not come on anyways but when it warms up i will listen for them

 

I've never heard of this disabling the fan. What climate do you live in? My fan has never come on, even towing in almost 90 degree weather, UNLESS I'm really low on coolant, then it's on a lot.

 

This only pertains to the new VXCF9 strategy. The fan will still work, but it will be a guess at what temp it will kick on.

I have had my fan kick on 3 times since I have owned the truck. The cooling system on these trucks are very good.

Normal operating temp for the fan to kick on is 225º ECT

 

Found this info about fan engagement while reading up on this more:

Engine temperature is not the only parameter that the PCM monitors to determine cooling fan operation. This is the reason that you will see some variation in engine temperature as it correlates to fan operation. The operation/description of the FSS (Fan Speed Sensor) from the PC/ED manual has a fairly good explanation as to how the system "thinks". This is not your traditional engine hits temp X and the fan clutch locks up. The fan speed sensor is a Hall-Effect sensor integral to the vistronic drive fan (VDF). The powertrain control module (PCM) will monitor sensor inputs and control the VDF speed based upon engine coolant temperature (ECT), transmission fluid temperature (TFT) and intake air temperature (IAT) requirements. When an increase in fan speed for vehicle cooling is requested, the PCM will monitor the FSS signal and output the required pulse width modulated (PWM) signal to a fluid port valve within the VDF.
