Well I changed both of them yesterday.

- Removed doghouse for the upper, disconnected air pipe from throttle body, put down a thick blanket on top of the engine so I could lay on top of it to reach the clamp on the radiator.
- The lower one was much easier, except that like most things it was not an exact fit but close enough. The heater hose pipes on the new one was 2' long, had to cut them and the original hoses and use couplings to connect.
- New hoses and SS clamps came from NAPA and cost about $100. I'm sure glad this happened at home and not on a trip
