Coolant for engine life
Bill R (verified owner) –
I personally would not run coolant for 150,000 miles unless there is a coolant filter installed. For my engines without a coolant filter, I drain and refill every two to three years. I trust Hot Shot’s extended life coolant for deposit control water pump seal lube, and corrosion protection.
