Maintenance Challenge Attention Requests

*##1 I have an 88 Mazda RX7SE in which I need to replace antifreeze.

Specific background: The shop service manual says "CAUTION a)Do not use alcohol or methanol-based coolants. b)Use only soft (demineralized) water in the coolant mixture. The antifreeze I have package is not clear but it seems to contain "ingredients: Ethylene Glycol (107-21-1), Diethylene Glycol(111-46-6), Water(7732-18-5), NJTSRN QT1" and "MEETS ASTM D-3306, ASTM D-4340". Request: Does this antifreeze conflict with manufacturers recommendation? Are glycols alcohol or methanol based? Mirwin 21:59, 25 November 2007 (UTC)
