Re: How Hard is it to replace Heater Core

The reason to do a combustion gas test is to make sure you don't have a EGR cooler leak. Exhaust gas entering your coolant can over-pressurize the system and cause leaks that otherwise may never show up. Not everyone does them, but i generally did it on any 6.0 I worked on, because its just another way to prevent mis-diagnisis or recurring problems.

Re: How Hard is it to replace Heater Core

All things considered that's not a bad price total for a heater core replacement.

Having done this myself I wouldn't do it for any less!

That would have freaked me out about the possibility of a head gasket leak, and I would have stopped driving it immediately. Of course, that's easy to say while sitting at a keyboard.


SMB-less as of 02/04/2012. Our savings account is richer, but our adventures are poorer.
