I don't think using harsh chemicals is the answer. I would consider it, at best, a temporary band-aid that may do more damage than good. But you may not have much choice at this point. YMMV

I'd do an inspection of the block (you may be able to use one of the cheap borescopes/endoscopes that you can find online nowadays) for corrosion before going too far.

I do have a borescope so i guess I'll have to get that in there, one thing to note though....this whole saga started a couple of months after i had the dealer do a coolant flush. The coolant that was in there beforehand i have no idea how long it was in there but it was still green in color. Before that i had no problems for the close to a year i had the car before i had them flush the system.

IMO a coolant flush, tranny flush are the worse 2 things you can do to a car. I've hardly ever heard a good thing about them It's mostly always been a horror story. Your's is just another one on the list of reasons why not to do it. The bottom half of your radiator could be plugged from the scaling that got knocked loose/dissolved from the chemicals they used for the flush.

Chemical flushes worked when engines were made of iron but anything strong enough to eat the corrosion is strong enough to eat aluminum.

Very likely. And any other small passages.

Flush was done before i swapped out the radiator and rest of system was filled and drained multiple times with distilled water to clear the system of the cleaner. Only thing that i didnt do is backflush the system with the thermostat off
