That level of a split case is mostly above=20 the oil level. Maybe the bottom inch would normally be emersed. The only contact it would have with the oil is what gets splashed onto it. Maybe that is enough to affect the temerature a little but not much.

Hmm, just to be sure we are talking about the same concept: in my opinion the cooling fins create the *inside* part, not the outside.... Even more if Bruce Loewen's assessment is correct, that the finned- tube is not *entirely* submerged, other than being splashed upon.... -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] Date: Wed, 25 Feb 2004 17:34:44 -0700 From: wayne@crushersrule.com Subject: Re: [DTLC] T-case oilcooler from Toyota?!?

No, no . The fins to the outside. Oil would be sucked up the rubber hose ( convection) cooled through radiation to the ambient air just like any radiator, then the oil would be spit back to the t-case through the upper fitting. That's how I see it. I still think its homemade, otherwise it would be cast.

The odd thing is that you can easily thaw up the T-case by putting it in neutral, and gearbox in gear, with idling engine.... So it's not a matter of life or death, go or no go. (though it might make the gearbox rotate _at all_, at some bizarre low temp's....having enough resistance of it's own, not needing the extra resistance of the T-case....) Remember that some folks don't get moving either with both gearbox and T-case frozen....

Don't think you can cast such copper/copper connections, and it's only copper you want, for thermal conduction (hence also soldered joints, not something press-/clamp-fit). Note that it is a reputable shop claiming that it is sourced from/through the EPC, not some mysterious seller or something....:)) A shop also known to source Cruiser parts from the MegaCruiser, for godknowswhat application. It's just that they can't figure out what the original purpose/intent was/is, cq what it should be connected to....:)) (that's my favorite way of discovering things too....just order something strange, and see if you can make it work, or even invent a new application....;)) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] Reply-To: dtlc@helios.net From: "The Penners" To: Subject: Re: [DTLC] T-case oilcooler from Toyota?!?
