When mounting the radiator to the support, are lock washers needed? I purchased a new aluminum radiator along with new bolts and cage nuts but was unsure if everyone is using lock washers or just some loktite.
Thanks.

 

I use flats, locks, and anti-seize on the bolt threads. This is a champion radiator.

 

Which fan/controller are you using Dave? I like that upper bracket, did you make it?

 

Hi Doug,
In this case the fan is PCM controlled, I just setup the on and off temperature set points.
For non PCM control I use Derale adjustable fan controllers which have worked fine. I would never buy a non adjustable controller, having the adjustment lets you compensate for temperature sending unit location and tolerances.
I made the fan mounts out of scrap round rod, pics are in the truck #2 build.

 

Thanks for the info, Dave!

 

Thank you.
