It should. Look for a white plug on the bottom edge of the radiator towards the back of the car.

What you're relating to is the radiator's drain plug. Other than that, what I'm trying to know if the engine itself has it's own coolant drain plug. The reason I'm asking because I want to totally drain all coolant in the system including that of what's still left on the engine (if ever there is still coolant left other than what was drained off the radiator).

AFAIK most modern engines don't have a drain plug, you could always disconnect the lowest water pipe you can find if you are really concerned..

You meant the engine block drain plug? It may have one, but I wouldn't know about it. Maybe someone else would know. Why do you want to drain all of your coolant? A radiator drain and fill is sufficient for most coolant changes.

Try this thread...no definitive answer, but the "speculated" region of the drain plug is also where my auto teacher told me it should be too. Worth a check.

Yes, the engine block... I replaced my original leaking radiator last Saturday with a new aftermarket aluminum radiator (KOYO). Also did a back-flush on the system using water from a garden hose. I know some might not see it as a big deal but I feel the urge and as per instructions of Pro-Blend to get all or most of that water off the system before adding new coolant and use distilled water for tapping. Also, with a new radiator and thermostat... might as well start clean too
As always, I'm using Pro-Blend IceWater which contains no antifreeze during the summer and a mixture of PB-IceWater + EG based antifreeze on winter months.

Hi Ev-one.. The tap would have to be located on the engine block between the rocker cover and the sump, and where its possible to reach it with your hand to undo it. So if you can't find one it's 99% certain there isn't one..
