Help! Safely removing heater
So Ive watched 10+ videos of others removing their heaters. My bus is a mini bird and I need some advice before moving ahead. 1999 GMC stv 6.5 detriot diesel.
Electrical: how do I safely disconnect the wires from the heater. Even with the engine off these are still connected to the battery correct?
Heater removal: I plan to:
Drain coolant from pipes from underneath the bus
Connect the lines with a copper u joint to close the loop
Secure connections with pipe clamps
Please let me know if you would do things differently. I haven't even gotten to drive my bus yet, paranoid if frying something crucial.
