This will be instructional information that you can not find anywhere else! The focus of the 25-minute video will be on removing and replacing the oil cooler thermostat once the oil filter housing is removed for a 1977 to 1985 engine ( excluding the 190D). Not every aspect of removing the housing from the engine will be covered, but Kent will show you the proper sequence to get the housing back on the engine block once the oil cooler thermostat repair or replacement has been completed.
