WOW....I just spent a hour reading up on a possible coolant flush and i might be more confused now than when i started! I just bought a 97 TLC with 152k. Coolant looks discusting, definetly needs a flush. Problem is I cant tell if its a dirty green or a dirty red. Am I safe if I just take it to the local Toyota dealership and tell them i need it flushed? im assuming they will use the toyota red, but im not sure if its red that would be coming out and I hear you dont want to go from green to red or vice verse. Im also assuming they posses the knowlegde to do the flush properly. Any thoughts?
