New light bar option

[Fishnerd]

Well I'm also trying not to block and of the air flow for cooling.

If you do a lightbar it might not block much flow. I saw this on another site (note he has a front cam and it sits right below and you cant tell at all that its there)

I’m personally shy of blocking airflow to the grille for cooling reasons, though I’m sure it’s fine because a) naturally aspirated engine b) I’m sure the radiator is overbuilt for users that are towing/loaded heavy up steep mountains

Air goes around things. Air would go right around the lights and into the radiator. They would have to be very large lights to push air around the radiator

Yeah I wouldn’t worry about airflow. These trucks have active grille shutters for goodness sake! Half the time I get out of my truck and look and they’re closed… Clearly the cooling system is more than up to snuff if the engineers felt the need to literally shut things down once in a while

Hmm. So watching my gages, a lot of times my water temp is above 210, even though it's not hot outside. Or us it ok for them to run hotter?

 

[jetrinka]

Mine is consistently 215-220ish. Seems hot compared to past cars I’ve had but research tells me this is where all the 6.4s seem to sit

 

[Rockcrawlindude]

Gas engines run 200-220° it’s called operating temperature

 

[jetrinka]

Not all gas engines. Seems like newer ones run warmer but 190-210 was fairly normal across the board through the 90’s and into the early 2000’s.

Diesels are another story

Yea, my 04 chevy runs 210 on a hot day.
But I ran my 350 FI I built at 180.

So did some homework, this is from a 1500 with a randy ellis bar provided from their nice lady on the phone. The other is from their website on a 2500. Doesn't look like it'll be too bad
