choosing the right coolant, this is a good read from popular mechanics ! Options

[Culpable04]

I've seen some water pumps failed in a matter of 4 months ( OEM pump on a camry 2001 ) and some engine badly corroded for something as simple as topping off your coolant with the wrong stuff,.

I know a lot of you already know this, but for those who don't and a reminder for the ones who have forgotten.

You can buy a flush kit for not much money. Flushing your radiator isn't the same as flushing the whole system. Basically without going into detail you flush the system by first draining the coolant. When the coolant is drained tighten the drain plug on the radiator and remove your radiator cap then fill with water. Put a t fitting on your heater hose and attach your garden hose to the t fitting. Start the car and and turn on the garden hose let it run for a while. If you get the flush kit you'll get a funnel that goes onto the top of your radiator that will make the water flow out of the radiator in a controlled manner rather than all over your bumper and engine. This is something you do in your yard, not your garage.
