Car Forum / Mazda / Mazda Miata / May 2004Miata radiator
I don't think my earlier post went through, if so, please excuse the reduncancy. I have a 2000 Miata, not spent much time under the hood, and I just noticed that the radiator "floats" and has rubber bushings at the top. Mine seems loose to me, but maybe this is normal. How much should you be able to move the radiator? Thanks for your help Clark Smith >I don't think my earlier post went through, if so, please excuse the >reduncancy. [quoted text clipped - 6 lines] > >Clark Smith Actually, your post did go through,but I am going to answer on this one. My radiator did not move at all. I recently had to replace it due to leak. I replaced it with a metal one. To move doesn't sound right to me. Anyone else? ~Cissy <a href="http://members.aol.com/IvaMiata/Krikkit/index2.html">My '90 Mazda Miata</a><br> <i>I love PC adventure games</i> The radiator in my '90 (and, I assume, others) is mounted with rubber bushings. I really don't know the design rationale behind the bushings. It's probably to attenuate shock/vibration from the frame into the radiator. One thing I do know is that the "float" should not be so great as to constitute "looseness". If so, I would assume the bushings are shot and need replacement. I also expect that a properly mounted radiator will leak for various reasons. Like Cissy, I also replaced my original radiator with a metal one. In mine, the interface between the plastic expansion tank at the top and the metal radiator decided to leak. Ken > >I don't think my earlier post went through, if so, please excuse the > >reduncancy.

I hope those visi.com fabulous CONEHEADS are at HOME!! Maybe it is the newer Miatas. My 99's radiator 'floats' a lot, just like Clark's '00. I was worried at first, but I have never had a problem with it, so I stopped worrying. Lathan > > I also expect that a properly mounted radiator will leak for various > > reasons.

OEM radiators have aluminum cores glued to plastic top and bottom tanks. Sooner or later, the plastic and/or glue fails. When the top tank turns olive-green, it's time to start shopping for a replacement. "All-metal" replacements are typically copper and brass, with soldered joints. There's a weight penalty of a few pounds, but they're cheap, and are invariably the automatic-transmission version, with a double core and more capacity. All-aluminum race radiators are available for about 3X the money.

After a year, the left side bracket on the replacement brass radiator separated from the radiator at the solder joint. It was replaced under warrantee, but I got to do the R & R! glen@ccim.net 94 "C" > >In mine, the interface between the plastic expansion tank at the top and the > >metal radiator decided to leak.
