You can but why bother with flushing it every season? Just buy some coolant and mix 50% water and 50% coolant and leave it for 3-5 years.

No. Use coolant. Otherwise rust will begin to form and you will cause a lot of trouble for yourself

Best Answer

Tom is right, as always, that's the reason I said that, you will have to flush it, besides coolant lubricates the water pump. I was not disputing Tom, we were typing at the same time

If your thermostat begins to rust up, it won't open. If you decide not to use coolant keep an eye on the temperature gauge

I hate rust.

That red coolant looks too much like rusty water, I hate that crap

That Red coolant, Dexcool, reacts with regular coolant to form a goo. Do not add coolant to the radiator if you still have dexcool in it. Clean and FLUSH the system first, then replace the coolant with a mix of at minimum 50/50, maximum 70 (coolant)/30 (water if you live in a northern climate where the temp can drop sub zero and stay there for extended periods.
