On a 1997 Deville: I want to drain coolant per the book- at both the radiator and engine block. GM service manual on engine drawing describes the block drain plug as "non-functional". What's up? Is the plug just there for looks? Is his plug really "non-functional"?

yoiu might try posting this in the N* section!
Someone earlier said the early Northstars had block drain plugs, but starting in year ????, they were eliminated.
Anyone know on what year they 'have' seen a block drain plug?

WOW! An 8 year old thread resurrected. This may be a record.

How about 2002.5 ? There is/are no block drains on a Northstar. The service manuals make specific mention of the fact - in the cooling maintenance section. There IS a drain plug in the bottom of the driver's side radiator tank.
The fact has been mentioned in here, Deville, and Seville since at least my join date in early 2006.
You'll have to zoom in on this.................

:yeah: also that coolant level picture would be great to explain about the correct level.

Correct coolant level: Where the tank halves meet.
Who needs a picture?

Anyone is free to copy that diagram/text and use it for private advice in here.
Even though it's straight out of the service manual, someone will eventually tell you it's not correct.....................
Here's another picture - this is a Gen. 5 Seville reservoir - if you look real hard you can see the FULL COLD and DO NOT OVERFILL legends as well as the arrow molded into the tank side. I hope that's correct enough................:rolleyes:
