DONE..... 1. open the air filter 2. open radiator cover 3. open alternator and follow the top radiator line to the bottom and you will see the thermostat housing. on 6.6 L duramax diesel has 2 thermostat 1 in the front the 2 nd in the back. make sure when you put the 2nd thermostat must be the same position before you took it of because 2nd thermostat has 2 hole and that hole must be in the same position.

It was pain job just take your time :thumbs:

Don't forget check your idler pulley might need to change :smoker:
