Thanks Paul I would like to hear more about how to plumb it, Since I read on one site that sells coolers that they suggested running from tranny to radiator to ext. cooler back to tranny. Any theories witch way would be better Any comments would be appreciated Larry Jabin San Francisco Larry@xxxxxxxxxx<mailto:L.jabin1007@xxxxxxxxxx> From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of Paul Holmgren Sent: Thursday, June 03, 2010 7:40 PM To: Chrysler300@xxxxxxxxxxxxxxx >> Chrysler 300 Club Intl Subject: Re: [Chrysler300] Overheating Issues Ma Molar has used tranny coolers in a lot of the modern cars. You probably do not need a massively sized unit if you want to also use the built in cooler in the radiator. I seem to recall that the 57's were close to the first cars with coolers in the radiator, some 55-56 trannys in Chrysler cars were not even water cooled, OR had a small device that aided in cooling some. I'll bet you can use a cooler from the late 90's Sebrings with out any problems. I followed some discussions about aux coolers, and it seems the consensis was to plumb it before the radiator cooler, usually folks kept the radiator unit in the system. My 80 Dodge truck has a factory aux cooler and they plumbed it with all rubber hoses and retained the radiator cooler also. -- Paul Holmgren Mine: 2 57 300-C's in Indy Hers: 05 PT GT R/T HO Stage 1 Hoosier Corps L#6 [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to: Chrysler300-unsubscribe@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/Yahoo!
