Hi Scotty I have a 2002 Chevy suburban, I am changing the water pump out and flushing the system several times. I am considering changing the coolant to the Toyota HOAT coolant. Is that a good or bad idea? I also own a 2005 Corolla and just want to not have different coolants for every vehicle. Thanks
