Okay got a 95 z28 about a week and a half ago, been fixing a hood since the old one was hail damaged and havent driven it much yet. As far as we know this car still has the original antifreeze in it still so we are wanting to flush it all out and put all new fluid in it. Looking for the best way to do this, any suggestions/tips for flushing it all?

 

honestly! If I had the original antifreeze since 1995 I would never flush it.
on the right side down on the radiator ( the passenger side, battery side)
the down corner there is a Tap loosen it and the radiator coolant would drain.
If u wana refile the radiator u have to open those bleeder screws to make the air out.
(on the right it is the water pump screw).
make sure all ur hoses are good. if u fell some are worn or making like balloon change it since u already drained ur coolant.
Iam ready to answer any question.
that was the radiator flush.

 

flush the motor, radiator and heater core separately. garden hose will hook into the heater core if you use coupler. flush both ways. get best results if you remove the radiator.
