Some of you may have noticed that the Diesel Trucks have a different lower front valance, Between the tow hooks, the bumper is open to allow air to enter and hit the inner cooler.  I want to add a light bar, and this spot is the only real-estate on the front of our trucks.  The opening will accommodate up to a 20" bar.  That being said, it will block about1/2 - 3/4 of the opening when installed.  Do you think this will impact the inner cooler?

 

The other option is to go smaller.  I can fit a 10" light bar in there, that will block about the same amount of air as the front license plate would, if installed.

 

I wanted to see your opinions before I want head and started looking for mounting options for the 20" bar.

Intercooler.  AKA Charge Air Cooler.

 

The intercooler is mounted on top of the engine.  What you would be restricting air flow to is the auxiliary radiator which is used to cool the coolant going through the intercooler, as well as the coolant through the fuel cooler as well.   

 

IMO, I'd be finding a way to mount one in the main upper grille.

I just cant seem to find the real-estate behind the grill with the active grill shutters.  And taking the grill apart is not something I want to do since I am limited to the tools I have on hand while here in Alabama.   (all my stuff is back in PA....)  There does not seem to be anything solid to mount to without building some brackets which I can't where I am at.

 

Also thought about removing the tow hooks to make up for the air flow that I restricted, but if I ever need to be pulled, I'll have no place to latch to...

 

And I dont like the way the hood mounted lights look.  Unless the truck is lifted and modified, they look out of place.

Yeah, I feel your pain. No winching bumper either for the LM2.

 

But no way would I block the inlet by 1/2.

 

Removing tow hooks won't gain you air flow.

You might be able to improve airflow by removing the tow hooks. surrounding them (for aero) is a rubbery part that they fit through. once the hooks are removed that part can be taken out also leaving an opening in the back. its about 50mmx100mm give or take. but there is also another plastic bezel that can be removed, 2 bolts and one clip. that would increase the size of that opening considerably, probably 2x-3x the area. of course air flowing through that opening would be flowing right into the open end of the frame. you would probably have to fab up some kind of duct to direct the air so it supplements what you lost in the center location. I'm not sure if its worth it, but it could be done. Just throwing ideas out there...

Another thing to consider though if you want to add more light, if you were willing to lose the tow hooks you could mount some light pods in that location where the hooks were, leave the center opening as is.

You would need to fabricate a mount that would attach where the factory bezel you removed attaches. but its an idea.

You guys anger me by bursting my bubble.   Haha.  But I appreciate it.  If the grill were easier to remove, I’d try to fab a bracket behind the grill.

Last couple days I've noticed a few around with narrow light bars on top of the bumper, in front of the grill.

Not sure what they were mounted to. (might be thru bumper, might be back thru grill)

    • I have a basic 2026 1500 WT  (2.7L/4WD reg cab shorttbed). Comfy, generally happy with electronics/radio - but is there a way I can add switches to steering wheel right-side position (curr. empty) so I can adjust volume, push phone button to voice dial, etc? Bill W San Jose  
    • The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.
    • So I purchased the Range unit for my 2026 and I am seeing different locations suggested for the ECM . Can anyone confirm wither under hood, left side or right side or behind the wheelwell?
    • Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that. 
    • "Life is getting back to normal."    I'm driving again and all new joints are operating as expected for this stage of recovery.   My most recent joint replacement still requires a lot of attention but experience has taught me that time will quiet the remaining pain.  I joked with my surgeon that another joint replacement would take my mind off my most recent surgery and he responded by saying the next will be a hip!  There are no plans for another surgery but, unlike me, I don't think he was joking!  I certainly wouldn't refuse further replacement  if required but hope to spend time out of the "post-op"  period.  I can't stress enough that if you have been recommended for total hip, knee or shoulder replacement that you welcome the offer.  Post-op "recovery" may sound daunting and painful, however, this is far better than the insidious erosion of mobility you are currently experiencing.  Imagine what it would feel like to wake up most mornings feeling better and more mobile than you did the previous day!  Prior to my first surgery in June 2025, even getting out of bed was becoming a formidable task.  Since the day after my first surgery, I get out of bed everyday easily and unassisted.  Making the switch to feeling a little better each day rather than a little worse, is hugely motivating!
