If you were to install, you'd probably want to flush all evidence of any earlier type of AF before changing to a different type. Some AFs are for iron blocks, some for aluminum and some--like Prestone--say 'for all engine types.' Plus, green AF is available pretty much everywhere, and MB stuff may possibly only be sold by dealers and requires payment of your first-born.<br></p><p class="io-ox-signature"><br></p><p class="io-ox-signature">Bob<br></p><p class="io-ox-signature"><br></p><p class="io-ox-signature"><br></p><p class="io-ox-signature">--------------------------------<br>Bob Spidell - San Jose, CA</p><p><br></p><blockquote><p>On August 19, 2017 at 8:53 PM healeymanjim <healeymanjim@hansencc.net> wrote:</p><p>have a gallon of mercedes benz antifreeze given to me by a neighbor. can this be used in a healey. have always used<br>prestone, etc.</p><p>_______________________________________________</p></blockquote></body></html>
