The life of a Magnum (and 46RE question)

2000 Dakota R/T.

The heater has never worked good.

The time I lost the radiator, I spent 2 hours flushing and back flushing the heater core with a pressure washer before it flowed through, with the last 30 minutes until it flowed clear.

It was so nasty I took pics.

I flushed it again the next week.

Heater worked for about a month.....

My mom has an 03 3.9 quad cab (because these are probably the last vehicles I will be able to work on without a theoretical physics degree, and $45,000 in software and special tools).

The day after I replaced my radiator, her's separated at the core to tank crimps.
