Pushing E fan and transmission oil cooler
 

Hello Hummer enthusiast

The summer the hot weather in my hometown
Im facing some humming sound since the temperature 115 f.

so im thinking to add additional electric fan infront of my car.
i found this fan, is it enough size and do you think that it will deliver the required to drop the temp


also my transmission i feel some weakness due to high mileage 150 k.
i heard some positive feedback to add a cooler
like this product

Tru Cool 40K Transmission Cooler Transmission Oil Cooler GVW Max 40,000

I need your valuable comments for this

Found this e fan installed in youtube

I seldom see 115 degree weather in Wisconsin (usa). We do however see -16 degrees.
I'm currently running in stand alone configuration:

B&M 70264 SuperCooler Automatic Transmission Cooler

• Rigid stacked-plate design is resistant to damage, and much better at cooling than ordinary 'fin and tube' coolers
• Constructed from black finished lightweight aluminum alloy for maximum corrosion resistance
• 11" x 5-3/4" x 1-1/2" model is rated at 14,400 BTU, and pressure tested to 200 PSI.Inlet Size: 3/8 inch nipple fitting
• Stacked plate coolers offer a step higher when it comes to cooling efficiency. The stacked plate cooler works almost like the plate and fin cooler. The main difference between the two transmission coolers is the amount of airflow involved.
  
  The stacked plate cooler has a design that allows easy circulation of air around the plates. This way, more heat is dispersed faster. This cooler is the top choice for racing, off-roading and towing vehicles. Some stacked plate coolers have integrated fans to increase the airflow and cater to especially high cooling demands for such vehicles.
  
  They use a non-threaded AN fitting to make installation and removal into the vehicle easy. This cooler will not work efficiently when mounted between the condenser and radiator. It causes the cooler to be inefficient. Mounting it in front of the cooler, however, will cause more efficiency and airflow.
  

Been running this since 2014. A small fan can be attached.

this is the fan i added ebay electric fan and i added this trans cooler both were not that hard to install. if you have the money pcmofNC has a kit with dual fans.

The down side with Pusher Fans is they are out front of the Radiator and when not on, or when on if not sufficient cfm flow, they can impede airflow to the radiator leaving the only net gain to be delivered at low speed or idle. Take that into consideration.

+Pusher fans sends more debris to the condenser/radiator, blocking the fins. https://cimg7.ibsrv.net/gimg/www.hum...c855e3533c.gif

how much is sufficient CFM? im trying to figure it out
and does the thermostat relay enough for electrical protection ?

here it is like living in madmax, often dusty during summer>>
also i just wash it using pressure washer and the engine as well
the radiator fins was super dirty >>so i will make it every quarter to clean them as a PM.

it looks great but im living is saudi arabia the shipment price will be higher than the parts itself:eek:

thanks for your feedback, but doesn't impact it during cold weather. like to reduce the fluid temp below the minimum level.

Put an additional radiator on the automatic transmission, move the thermostat up (185-189 F), set the electric fan. Only then will the cooling system work normally.

Put this pair of 10” fans on mine. Works like a charm. Sat picking the kid up from school for 45 minutes with the sun right on the grill and stayed at half gauge. 107°F. My only worry is the alternator keeping up.

That wood dowel is meant for a garden tool handle, clothes hanger rod,etc. NOT intended to prevent hood from cracking open you cranium. Get yourself a new set of hood lift supports! https://cimg3.ibsrv.net/gimg/www.hum...853b755de0.gif

So trust gas struts that most definitely do fail and not the stick that has never failed?

Your temp was half at 107F?

Works well parked which is to be expected when blocking off so much Radiator. How about 70MPH fully loaded or pulling a Trailer for a couple hours?
