Hello All!
I just bought 2 gallons of Nissan Long Life Coolant for my '99 Nissan Maxima. I want to drain the radiator and re-fill with new coolant. After driving several days, I want to repeat the same steps again to get a higher percentage of new coolant mixed in.
I read on some boards that changing out the coolant on a hot engine is bad as it can warp the heads?
I will be doing this at my mechanics shop so the engine will be hot from driving. Should I wait for the engine to cool or is it safe to drain on a hot engine w/o re-precautions.
I would think most shops do not wait for engines to cool before they do radiator service on customers cars. Are they changing the fluid in an incorrect manner than?
Also, am I doing the right thing by changing the fluid twice so that a higher percentage is mixed in as I am not connecting the radiator to a flush machine as I am strictly sticking to Nissan Coolant to keep things safe.
Thanks a bunch!
