I poured in that "Bar's Leaks" product you recommended in a previous video a while back and it completely stopped the leadking.
That's a temporary band-aid. Continued use can result in a plugged up heater core or cooling system.
I need something that will last.
"Stop-leak" products won't.
I really don't want to spend near $200.00 for an all metal radiator, that is way too much money but I need something that will not break like the plastic ones.
Assuming it's original, the OEM type radiator with plastic tanks lasted 15-16 years. How much longer would you need a replacement to last?
Rockauto.com shows a Denso radiator for your car at about $109. (There are cheaper ones but you're better off sticking with leading brands.) Chances are it would last the remaining life of that vehicle.
As far as the all-metal aluminum radiators, I installed a "Champion" brand unit in one of my older vehicles a couple of years ago and it's been fine. Construction is quite solid and I see no reason why it wouldn't last a long time as long as coolant is changed regularly. In my case however it was either spend about $200 on that or $500+ on a custom original style radiator which for that car was brass & copper construction. (I didn't want to try Frankenstein-fitting a more modern $100 radiator.)
