Air Deflector

[Boone]

I think I was told years ago that these direct air in such a way that helps cool engine. I can't remember who said or the specifics of the conversation. So is this correct? My truck doesn't have one. with an Al. summer on the way I thought I should check into it.

Are you asking about the one that goes under the front bumper? Like a chin spoiler?

 

[Boone]

Yep thats the one.

I think those were more for directing airflow away from the undercarriage to help with fuel economy. As far as I know, they were never used on the 3/4 tons which generally get worked harder and would benefit more from any additional cooling the air dams provide.

The oem cooling system is more than capable of cooling your engine provided it's in good condition. The engineers that designed it took into account that some of the trucks would end up in hot climates so if the radiator, water pump, fan clutch, and coolant mix is all up to date you have nothing to worry about.

Sounds good. Everythings in good working condition (i hope). Just noticeda slight difference on the gauge since we've had a couple 80+ days.
Thanks

Do you have AC? Check between the radiator and condenser for debris. I had a bunch of leaves and fuzz stuck in there I shop vac'd out. And there are seals on the sides too that can fall out and cause engine compartment air to get sucked through the radiator.

No a/c was removed before i got it. The new grilll we made has also got me concerned. I hopge it has enough air flow thru it.

Yea I'd put two more our one big one. Then put mesh behind the grill. The kind they use on gutters
