someone recently told me that I should put straight undiluted coolant in my radiator after flushing it. Says it works better and without water won’t corrode your parts as easily. I think he’s full of sh*t but has anyone heard something similar?
NEXT!
Sure pour undiluted into the radiator if you add an equal amount of water to the system. Probably more corrosive without water, and won't cool as well without the water. Could overheat in the hotter months.
