Engine/Transmission (1998.5 - 2002) Heater Core Restrictor?

[Bobcat698]

I need to replace the heater core in our 24v dually, we're getting coolant in the cab (fun fun).



I talked to a customer of mine that has a 97 12 valve, he said he's replaced 3 heater cores in his truck. Apparently after he replaced the third one he was talking to someone that said a restrictor is made that goes before the inlet of the heater core, which will reduce volume & pressure into the heater core. . and that Cummins equipped Dodges are notorious for blowing heater cores.



Is there any truth to this, and if so where would I get this restrictor? I only want to do this once!



Thanks for any input!
