Hey everyone,
I need to replace the fluid in my MR2. I have used the red Zerex 50/50 premix asian car formula for maybe three changes across nearly ten years of ownership of the car. I would prefer to get something concentrated this time, to save money, since the car requires approximately three gallons of coolant. I was looking at Peak Original Equipment Technology Red/Pink. But I started thinking... did they even have red/pink coolants in 1987? Is there a possibility of chemical incompatibility with this older car? I had to bypass my heater core because it started leaking. Is it possible that the Zerex coolant attacked the solder joints?
I guess my question is... what coolant would be best for this car, and will I run into any compatibility issues or sludging when switching over from Zerex Asian 50/50 red?
