I saw the vid on getting behind the bumper to drain the cold side coolant before a TMIC swap. That's only needed if a coolant change is needed.

Here's the easy way to swap a TMIC.
See the pix. Use a 2-foot piece of silicone hose, 24mm Inside Diameter (2-4mm thickness). I used plastic tube from H-Depot but plastic doesn't flex easy like silicone.

Remove CF brace.
Place a rag or two.
Uncouple top fitting quick & place hose.
Route black hose to bucket.
Blow in hose to drain TMIC to bucket.
Tip towards you to drain good. Blow.
Level out TMIC and remove hoses.
Place cut glove fingers over fittings.
Lift out TMIC and swap frame/res.

To refill, attach the plastic/silicone hose as before. Pour Wetter into BLACK hose, then the coolant. The inline motor will block you from filling fast, go slow and watch down the hose. When you see coolant in the clear tube the TMIC is mostly full. Reconnect that last fitting, top off, purge cycle, purge cycle, done. Drive. Check again next morning.
