what coolant to mix

Yesterday I noticed my radiator overflow tank is just about empty. What kind of coolant do I add to it to fill it up? It's a 2006 2.4L and probably still has the stock fluid in it.

Use the coolant type specified in your owner's manual which is a HOAT. Or temporarily you can always just top it off with distilled water which your local grocery store carries by the gallon. Not filtered water, use only distilled water which has none of the dissolved mineral content present in most drinking water. Most tap water is high in dissolved mineral content which when in a radiator, is bad news.

When you completely flush & refill your cooling system, a HOAT coolant like Zerex G-05 is a good way to go. Or you can just add some Zerex G-05 premixed HOAT coolant now which better parts stores like NAPA carries. My local Autozone stores don't carry anything that good.

I'm not sure which type of coolant you need , but probably should flush and change if it is 7 years old. IMHO Your owners manual should tell you what type you need. You need to find out where that fluid has gone to. Is it leaking or possibly a bad radiator cap.

Thanks guys, very helpful.

Would this work well/be efficient. If I don't want to flush the system with a garden hose and all that would this work.

Drain the radiator, fill it up with distilled water, drive it around until it's warm. drain the radiator again, fill it with distilled, drive it around, drain radiator again. Fill with 5 quarts straight HOAT and top off with distilled. Would that work, and flush the whole system?

Autozone sells those prestone flush kits for approx. $5. I think that would be a better option.

What I do is drain everything, pop the lower rad hose off and pop the heater core hose that goes to the thermo housing off the heater core. Then stick the hose in the heater core hose and back flush everything. It's a good idea to flush the heater core separately because you don't want the crap in there getting into the engine passageways.

Well I don't have access to a garden hose. I live in an apt, and also I just moved and don't know a single person in the area, so what I posted in #5 will that method work well?
