im gona replace all my fluid's 2day and i know where the drain plug is on the engine but im not sure about where the radiator plug is...lol i guess i can look in my hanes book

 

There should be a small petcock toward the bottom of the radiator. It's plastic and looks like a big wingnut.

 

They usually break off due to age. A better piece of advice is to pull the lower rad hose. About the same amount can then be drained, and it even works on radiators that lack the petcock.

 

i usually just use the plug on the center housing.

 

yea i broke the plastic plug lol but i went and got a real bolt lol thx guys

 

Okay, is it just me, or does it seem kind of ridiculous that there isn't a drain plug on the stock rad? Even on my aftermarket 3-row rad I don't have one. Is there any reason for this, or did the Mazda engineers just think it would be funny to see a bunch of sorry suckers cleaning coolant off of their engine bay and crossmember?

 

ditto!!

 

Put anti-seize on the petcock threads.

 

3 rows didn't, 2 rows did IIRC.

 

SA radiators don't have a drain on the radiator

 

Along with a hose in the radiator, you'll flush the whole system.

 

Oh, CLR and LimeAway work wonders to clean out the cooling system.

 

yeah I would just pull the lower hose, and get a flush kit at the store, becuase you can drain it all you want, but if you dont flush the system you are just shooting yourself in the foot
