Are you saying it's blocked or is it leaking?

To replace it requires pulling the dash back to remove the HVAC box.

If you've never done one before plan on spending 6+ hours doing it.



I was afraid of that , my 2000 cummins Ram is not blowing very cold , the rad is full and it comes up to full temp ... BUT my antifreeze is about 130k since last flush and my thermostat is the original , hoping it's not the core
