How to perform a proper coolant flush
Does anyone have a write up or instructions on how to perform a proper coolant flush after having to replace a faulty oil cooler? I am replacing my cooler and want to make sure i follow the proper procedures to prevent it from happening again. I am mainly looking to see what I need to disconnect to fully empty the system. I drained at the coolant tank pet**** last night but only got about 3 gallons out that way. Is there an easy way to fully drain all of the
coolant? The TSB for this states that you need to remove plugs from the heads as well as hoses from the heater core. The tsb also says to let the truck run at 1200 rpm for 1 hour to flush properly, how do I achieve this without having to sit in the vehicle for an hour.
