Question:
i pulled the plug out my radiator and nothing came out, what do i do? i really need to flush my coolant system .... BAD
Answers:
Use something flexible to run back and forth through the drain hole a few times,maybe a small wire or a coat hanger, be careful not to force it to hard you don't want to puncher the inside of your radiator,If you have a small wire brush you may want to try that.
I have a 2000 Chevy Blazer 4.6 L Now it cranks and only back fires why is this?
Sounds like your cooling system has never been flushed. I would try a Prestone flush and fill kit and install it as per instructions on the package and then hook up your garden hose and turn on the water (not full blast) and let it run. A lot of the coolant will come out of the plastic tube that snaps down in the readiator cap hole at the top of the radiator. Your engine has to be running while you do this. If you can salvage the cooling system I would refill it with Prestone 50/50 premix which is half antifreeze have distilled water(a must for your cooling system)More Questions & Answers ...
