Thank God for Chevy's

I sold my 2001 F150 cuz of heater core needing replaced. TRG was over 10 hours= well over $1000 10 years ago, plus ripping entire dash out and friggin air bags...no thanks. All for a $50 part.... Had over 300,000 kms on it so it didn't owe me anything.
Heater core replacement?
