james750 Posted January 15, 2010 Share Posted January 15, 2010 I have a manual trans, and therefore no need for the trans cooler in my radiator. Could I use it as a power steering cooler? Anyone know where I can get fittings that would allow me to clamp lines to, right now there is just two plugs in the place where the fittings should be?

knever3 Posted January 15, 2010 Share Posted January 15, 2010 I don't know if it would help that much? I know the trans fluid gets way hot and the 200F water cools the trans fluid, and when the truck is cold the trans fluid helps heat the antifreeze to warm the truck faster. Myself I would use a trans cooler for around $35 and have Car Quest make some hoses up for me. Any machine shop or hydrolic hose place can make you hoses with good crimped on fittings. Do you have A/C? The extra electric fan in front of the trans/power steering cooler would be awesome! Quote Link to comment Share on other sites More sharing options...
james750 Posted January 15, 2010 Author Share Posted January 15, 2010 Only reason for adding a cooler is because I am looking at putting in a PSC pump, that requires a cooler. Quote Link to comment Share on other sites More sharing options...
jpnjim Posted January 15, 2010 Share Posted January 15, 2010 I used an external tranny cooler as a PS cooler in my last MJ (PS would go out after it got hot on the trails). Simple instal (plumbed it into the return line), and it eliminated the problem, the cooler in the radiator might work too, but the external type is cheap, and will definitely work.

ParadiseMJ Posted January 15, 2010 Share Posted January 15, 2010 The "cooler" on the radiator would "cool" your PS fluid to about 200F. The plumbing in the radiator is not really a "cooler", just a heat exchanger. In an automatic it's there to bring the trans fluid UP to temp faster. It can't cool any cooler than the temp of the radiator (~190-210). An external cooler plumbed to the return line and in front of the aux. electric fan would truly cool the PS fluid, especially at low speeds. I like the external cooler idea, that's going in when I replace my leaking pump Quote Link to comment Share on other sites More sharing options...
maddzz1 Posted January 15, 2010 Share Posted January 15, 2010 There is a NOS tranny cooler for an 84-86 MJ/XJ on ebay right now. $20 I think. Should be able to make it work on later years. http://cgi.ebay.com/ebaymotors/NOS-OEM- ... ccessories Quote Link to comment Share on other sites More sharing options...
