The easiest way for me to change the thermostats was to remove the bracket on the top of the thermostat housing, remove the oil fill tube and just remove the thermostat housing. Didn't need to remove anything else on my LBZ. Just remember to get new orings for the thermostat housing to upper radiator pipe and oil fill tube. I always change the oring for the thermostat housing to radiator pipe when doing this job. Use a little dielectric grease on the oring so you done roll or damage it when putting it back together. You don't have to always replace the oil tube oring. I just keep one on hand just in case the original one is bad when removing / installing the oil tube back in. After the install of the thermostats, I install the housing back on and torque the bolts leaving the thermostat bracket off. Install the oil fill tube back on. The do the bleed process. With the thermostat bracket on you can't get to the thermostat bleed screw. And when your bleeding the air out, you don't want to get coolant in your oil so that is why I reinstall the oil fill tube. |

It is foolproof though, the long one will not fit in the short location.  |

See attached pictures. * Had to remove these brackets so we could pull the thermostat cover off. * thermostat cover pulled off. * I also pulled the oil fill tube out. Not sure how you can pull the thermostat cover off without doing that! Thermostats Part number from O’Reilleys is #44748 Hope this helps anyone.

| 1DurtyMax | Thanks a lot! This was great to use on my lbz. Only difference was the oil filler neck had to be removed ( only 3 bolts) and no drain on my radiator so I pumped 2 gallons out of the reservoir box into a couple jugs and didn't lose any coolant. Thanks again |
