ok not sure what bleeding the rediator is exactly. Can you explain pleez. I have the stock rad I have no Idea what type it is though proly aluminumumumum.

 

The upper rad hose goes from the filler neck above the water pump (where your rad cap is) to the top of the rad. It doesn't actually go to the rad itself, but rather to a plastic tube coming off of the top of the rad.

On the side of this plastic tube is a plastic screw with a Philips head. This is the bleed screw. Remove it. Fill the rad cap hole slowly with whatever you're filling it with (flush, new coolant, etc.) You'll be able to hear the fluid running into the rad. If you fill it too quickly the fluid will come out of the bleed screw hole.

When you've filled the rad (fluid comes out of the bleed screw hole no matter how slowly you pour it) put the bleed screw back in (and reconnect the heater core hose if you've pulled that off as suggested) and top up the fluid. Done.

After you've finished all the flushing and put fresh coolant in the system, you'll want to check the coolant level again after you've driven the car for a bit. There will almost always be some air left behind after a flush n' fill. Waiting until after an hour or two of driving will give that air a chance to work it's way through the system and out to the highest point (the filler neck.)
