Anybody replaced lower radiator mounts while the support is in the truck?
I have discovered that besides going with a custom aluminum radiator, I will not find a drop in replacement. If you go to buy a replacement from Autozone, Napa, Rock Auto, etc., they will have the right core size, but all are made to fit the wider 4 core mounts. I was trying to get away with finding a used one, or just a cheap one from the parts store to hold me for a couple years until I tear the truck down. I already have a 4 core radiator so I figured I would see how much of a pain it is to install the 4 row mounts in my truck. It looks like a pain in the rear, as the mounts are right over the frame. Has anybody swapped them while the support was still in the truck?

If I remember correctly, the bottom mounts just sit in place. There's a tab bent into the bottom of the mount and a corresponding slot in the bottom of the core support. There really isn't much mechanically holding the rad in place, just the friction in the mounts. Lasted this long though.

The lower rubber pad holders on my core support were riveted on so you would have to drill them out. With the radiator, shroud and fan removed you should be able to get in there to remove the old ones. The four core holders are longer so you have to bend the core support lip out a little to seat the holders.They won't move with the radiator in place so no rivets are needed.
Not an easy job but can be accomplished. |

The tuff part is getting a wrench in there to tighten that little bugger between the frame and the bottom of the core support. It can be done, I have done it twice now. |

I used an air chisel to get the rivets off, then just laid in the lower radiator supports that I purchased thru LMC. I'm running an original style brass 4 row radiator, but I'm sure the aluminum ones mount similarly. I highly recommend using a fan shroud, and perhaps a fan clutch. I don't have the fan clutch and the underhood noise is kinda loud.
