Hot Air
Backstory: When I bought my 79 F150, the PO must have special ordered it with an oil bath air cleaner. When I removed it to clean the element, it completely fell apart so I just threw on an aftermarket parts store air cleaner that pulls hot air from the engine bay. I finally found an OEM air cleaner that I plan on putting back on.
Ok, on with the question: Now that the weather is getting warm, and running with the AC on, my trucks temp starts to creep over 210. I know this temp is not that concerning, but it wasn't even really that hot out. Will putting the factory air cleaner back on, with the hose pulling air from the grille help with keeping temps down? I don't know if pulling hot air from the engine compartment would make much of a difference as far as running temps. The reason I'm asking instead of just trying it, is that the OE cleaner needs a lot of cleaning and restoring before putting back on. I wasn't sure if it was worth the effort. Thanks!

It does have the shroud, and I can't say if it ran hot before. I bought the truck late last year and didn't get an aftermarket temp gauge installed until it was winter and it was a non-issue.

It has a new radiator and thermostat (correct one), so I may need to do a flush of the block. My water pump may be on its way out also...I think it's original. I'm trying to make it to this fall when I plan on pulling the motor for a refresh I was just hoping pulling cool air from the outside would help bring the temps down a few degrees.

My AC guy tells me there are (at least) three fan clutches. I thought I had the heavy duty, but he said it was spinning too freely. I replaced it with a severe duty.
Other things to check:
I live in Yuma, AZ (doesn't get much hotter than here) and have aftermarket style air cleaners on the three trucks - not a problem!
Other things to check:
- flush block
- flush radiator
- consider the heater core as an extension of the radiator
- sticking / proper thermostat (just because they're new doesn't make them correct or functional)
- correct or heavy duty fan (size and number of blades)
- water pump / backing plate / cavitation
- hoses
- fuel mixture (lean=hot)
- fan shroud
- fan belt tension
