Radiator Damage by Gravel

I have a 2002 Magna 37' that has a newer copper radiator in it. I went on a small trip and found it leaking from the inside cores of the radiator. I see this nice new black radiator with all of these little copper spots in it. Upon further inspection I found that the inside back corner of the inside of the shroud was 3/8" deep in gravel. All i can assume it that the gravel kicked up from the road and some how got collected by the fan and spun into the radiator shroud. Has this happened to anyone else???? Has anyone made a shield or guard of some sort to keep this from happening again?

I have a steel and copper radiator and i just went out and looked at mine and the rock shields (1 is 18" wide and 1 is 8" wide) under the radiator. Maybe when the radiator was replaced they left them off

Would you mind taking a picture of your shields so I can fashion something similar?

Thank you

When I had our '02 Dutch Star at Spartan I found that they had an expanded metal rock guard for our chassis. I bought one and installed it. It was starting to break apart when we sold the rig so I removed it. Simple thing, just expanded metal, cut to fit and one bend, held on with a few bolts and wire ties.
I don't remember seeing one on the Magna so I didn't worry about it since the rig has gone 45,000 miles without one.

I think there is some kind of shroud. My Magna can suck or kick up gravel in the area behind the radiator Grille very easily just from the suction of the cooling fan. There's always some gravel in there. I have driven many miles down bad gravel roads it never caused any damage to my radiator or charge air cooler but I have a steel radiator. Of course what you're looking at through the grill where the gravel collects is the charge air cooler not the radiator. All of these are aluminum.

I was out getting ready to replace the Allison filters, install the air line for the BrakeMaster toad brakes and lube the driveshaft so I too a good look at my fan/radiator setup. NO rock guard of any kind. If I was going to AK I certainly would add one, even if just a piece of aluminum expanded metal. It wouldn't be hard but sure looks necessary to me.

This is what my radiator looks like now with no protection:





2 Strokers looks like this:



I will let you know what I do for mine when we go back together.
