Blazer coolant replacement
Can anyone explain to me how to drain, flush, and refill the coolant system in my 1999 Chevrolet Blazer? Including the best way to get at the radiator drain plug? I bought DEX-COOL and a bottle of radiator flush. Please be as specific as possible.
Thank You!

A quick search should give you a number of good ideas. Try terms like "flush", "radiator+flush", "drain", and/or "radiator+drain".

Can't find anything specific enough

STAY AWAY FROM DEX-COOL!!!! IT WILL CORRODE YOUR INSIDES OF YOUR ENGINE!!! drain and flush the system out with the garden hose and run the truck for a little then do it again...then go buy Preston GREEN antifreeze and put 60% distilled water and 40 Green antifreeze..........

So, back to the topic at hand... What, specifically, is it that you are having trouble with? Or would you just like someone to walk you through the whole process before hand...? It is really not too difficult. Just get in there and have at it.

I went to harborfrieght tools and bought this little kit that has a funnel thing and some fittings and a T. you put the T in your heater line then hook a garden hose to it. then you put the funnel in your RAD fillup hole and turn on the hose. it makes a mess though, lol. it sprays all the rad juices all over infront of the truck, lol. but in my opinion if its really dirty in the coolant system youll need to pull your large rad hose and wash it out as it collects alot of the "chunks" in the system. also if the system has alot of "chunks" you may want to pull other hoses too. I say this because if you force those "chunks" through the system u may damage the internals, ie rad or heater.
also it seams to be a little know secret, but the rad drain plug is an alanhead.

The easiest method to drain the coolant is to disconnect the lower radiator hose. It definitely is not the neatest way though.
