Having problems with your 1993 Oldsmobile Cutlass Supreme ?

Radiator flush I need help with flushing the radiator. I was told to use streight antifreeze then someone else said to use mixed antifreeze. I also need to know if anyone can tell me where the drain plug is? Can anyone give me a walk thru on how to do this?

Answers :

Drain plug is on the bottom of the radiator. Should have a tab for the plug. PLUG DOSN'T COME ALL THE WAY OUT, you're only able to twist it so far. IF your confused, just undo lower radiator hose and have a big bucket. The anitfreeze you put in your car has to be a TOTAL mixture of 50/50. You can buy premixed 50/50 for a HIGHER price! If you don't want to pay that much, you can get STRAIGHT ANTIFREEZE. If you have an extra gallon jug around the garage, fill half with water and half with STRAIGHT antifreeze and tada! You got 50/50 antifreeze. Hope this helps ya.
