All metal Heater Core availability?

[ElecTape]

Doe's anybody know of an all metal (Coper Aluminum) heater core for 2005 KJ liberty. I've had to replace 3 in the last five years all because the plastic top cracks or pipe breaks on them. I thought I'd found one on RockAuto by GPD, Image shows all metal Tubes and core, but when it arrived today, I got the usual plastic top & tubes.

Ugh!

That's terrible luck, but everyone has some back luck sometimes I guess....

I can't say I've ever heard of one failing anyone though. I've had 2 Liberties with a total combined ownership of 21 years. I feel like maybe aftermarket/Chinese heater cores? I wonder if you're pressure is maybe higher than it should be? (head gasket leak maybe?). See if you can find a used OEM Mopar unit and give it a try.
