Crashed Truck Sat 3, 4 Months - Do I Need to Flush Before New Radiator Install?

It has been about three months since I wrecked my truck. Yeah, I wrecked!
It's not so bad, but unfortunately I deleted all the pictures of the wreck so no - you can't see it.

It destroyed my front bumper, radiator, condenser, and radiator support. However, the damage was done to the front right of the truck; I had to replace all the above as well as the engine air box.

How? I was being impulsive and ran myself into a guard rail that was covered by weeds; low speed crash. Anyway, I am skeptical of just installing the new radiator, topping off and starting it up assuming it doesn't need some kind of flush.

I also overheated the engine on the way home for about a mile and once more for a two minute period at a stop light.

The truck has been sitting for three months without a radiator.

Question: Because the truck has been sitting without a radiator for three months (with the hoses taped off), should I assume it's okay to just install new radiator and and top it off with fluid?

Or should I: Buy an old radiator, run coolant flush thru, drain, then install new radiator?

I'm not sure how the innards of an engine hold up to being exposed to the elements without a radiator.

 

When was the last time you flushed your radiator? If never then you definitely should do it but unfortunately you can’t flush it through the old radiator prior to installing a new one but it can’t hurt the new radiator. I say do it!

edit: reread your post. If you could buy a used cheap radiator from a pick and pull prior to installing a new one that possibly might be the safer method but I don’t know how necessary it is. I flushed my old radiator and didn’t see any large chunks of sediment which makes me believe if you installed the new one and flushed it out, it wouldn’t hurt it. Just a guess, someone may chime in with more knowledge on how to properly flush a radiator. Sorry I couldn’t be any more help.

 

Slap in new Rad. fill with pink and drive it like you stole it

 

Wash, rinse and repeat. At least for peace of mind. I had a rebuilt 3RZ sit for 3 weeks and did that, didn't see anything weird and its one less thing to worry about.

 

Thank you all for the replies.

I'm going the easy route on this one.
I've driven the truck about 10,000 miles since I bought it and although I have not flushed before, I think it's all good. I will do a simple water flush, but I won't be taking it the whole nine yards with a flush solution.

Now if only I could figure out the issue I'm having locating the passenger's side A/C Condenser mount bracket that seems to be a mystery part, I will have all the parts I need to put it back together.

Edit: Perhaps if during the water flush I see some debris, I might go that extra eight yards and do a proper flush.
