Radiator Drain Valve ?
 

Is there a drain valve for the radiator? Asking before I get under there looking for it.

I don't think so. usually to drain people remove hose on the bottom of radiator.

Yes! Yes there is! It's on the right (passenger) side like just below the head light kind of. Obviously somewhere low, you will have to remove your splash pad to get to it.

passenger side. there is a little clear hose on it

Great! Thanks!

little trick.. im sure u already know, but remove the valve first, then the radiator cap. less mess.

and for those of us that didn't... thanks!

Use this to refill. No mess, no funnel BS, no bleeders to open to burp/bleed the system. Requires a compressor.

After opening the drain valve, attach a small hose to keep mess to a minimum while draining. Good idea to change the radiator cap too.

Is it the same burping process for the Z. As is for all other cars? Draining, refilling, running till fans kick in, refilling/checking leve's, etc, etc

There's also a bleeder valve on the inside of the radiator. Driver side near the belts. This helps with the emptying/bleeding process.

Using the tool I mentioned earlier does not require messing with bleeder screws or running til the fan kicks in. It makes refilling the system literally a 5 minute job.
