2nd Trans Cooler

Had the trans cooler/radiator issue last fall and did the cooler bypass. Now that it's getting warmer, I'm wanting to add a 2nd small external trans cooler to make up for the loss of the one in the radiator. What are your opinions on this? Is it really necessary (specially with the summer heat)? Is there a downside to installing it if it's not really needed? Thanks!

Uhhhhh, the Frontier is a Nissan vehicle, not a GM vehicle. Our Tstats open low, in the 170s and if you install a 350z Tstat, it is in the 160s.

I would suggest that the OP just run it as is and see if the temp gauge moves at all. I know I have been running mine bypassed in FL for a while now and have yet to have any issues. If you notice the gauge moving, then just add a fan to the OEM rad cooler and see where that gets you. If you need more, then upgrade the cooler.

Side Note: Just putting this out there, it may be worth checking out the cooler that is used on the Titan since it is rated to tow more then the Frontier, thus more heat/stress. If we use the same, then you should be good to go.
