I couldn't find any topics on 4 Gen T4R heater core replacement, only 3 Gen, but I did find where the AC evaporator had to be replaced and if I'm not mistaken the heater core is in the same general area/box as the evaporator.

I hope you are good at taking things apart and getting them back together correctly because you have to take everything you see in front of you when you're sitting in the seat apart to get to the evaporator and I'm assuming the heater core, i.e. entire dash and assorted pieces, etc.

Here's what your dash area will look like by the time you get to the evaporator, the first photo is a 4 Gen 4 Runner, the second is a BMW, but both pretty much involves the same crap that has to come apart, the last photo is the 4 Runner back together again.

Thanks for the response! The new heater core I bought is no good it leaks by the crimps where the intake and output tubes are.

Have to send it back and try again next week. For not i've just bypassed it.
