coolant change time, need advice
Ok, need advice on how to get as much coolant out as possible. Am going to change to Evans waterless coolant and their website says do not rinse out with water as its better to have some coolant in there that 50% water than some thats 100% water. BTW, cannot have more that 3% water by volumn or corrosion issues will result.
Will just draining bottom rad hose get all the coolant out of the heater core? What about the bleeder plug? Do I need to pull any hoses off heater core or engine area? I still have the egr cooler hooked up, but it has become not needed since the Cali style deletes.

I changed mine at 120k. Was concerned that the cheezy pastic valve on the bottom of the radiator would come apart, and the bottom radiator hose is not actually at the bottom, so I picked up about 6' of clear plastic Tygon tubing and used that to siphon the coolant out of the radiator. With the truck parked facing downhill, the heater on, and the bleeder open, I was able to get 4.5 gallons out. Replaced with the recommended Zerex G-05 HOAT coolant, so I was not too concerned about the gallon of remaining coolant.
