Reusing Your Stock Oil Cooler

[racedaymechanic]

Ive been reading some comments about Oil cooler Lines so I though I would repost A thread I put on another Forum:
How to reuse your Stock Oil cool with AN Lines, The Stock oil cooler in your 6.5 Is a very well built Cooler and it is made By Long Manufacturing, But comes with those push in Oil lines that are prone to leaking or letting go alltogether, By screwing the Old fittings out of the cooler and Using -12 An Union fittings in there place you can hook your Braded line right up to your existing cooler, One thing to note If you have spun a Bearing or anyother kind of major failure DO NOT REUSE YOUR OIL COOLER! Throw it away, That being said I like -10 lines so I use a -12 X -10 male to Male Union Reducer it is a Aeroquip fitting Part Number FCM2762 about 10 bucks each you will need 2 When taking out the old fittings or Installing the new always use a 1 1/4 inch wrench to hold the Cooler fitting so you wont damage the Cooler, I use a little Teflon Pipe Dop on tthe Threaded part of the -12 side you thread into the cooler tighten it down pretty good and it will never leak

This I believe only applies to the 97+ with the larger lines as my 95 replacement oil cooler has the fittings as one piece with the cooler. I'll check em again later, but I'm pretty sure they don't come out of it. My tranny cooler though does un thread like yours.

This is the same thing I did for the cooler on my 94. I don't remember the sizes of fittings used but same idea.

Wow, I just replaced mine with the Lubrication Specialties kit. The old cooler went with the AC evaporator and dryer and all the beer cans to the recycling yard. Did not realize there was a developing aftermarket for
old stock 6.5 oil coolers.

I posted on this a long time ago across the forums, the fittings that I used are technically correct for the 97 and on coolers. Not doubting that you managed to obtain a seal using a regular flare fitting and some dope just that there is a more appropriate way to do this.

I had a buddy tig weld a 3/8 pipe thread bung to mine for a guaranteed seal!!

I was toying with making my own this time around. The Lubespecialist kit was worth the money but I was not in love with the way the lines had to be routed. They rubbed along the dipstick tube and the Oil Filter adaptor. I wanna giveit a good looksee and see if they canbe run a different waay with longer lines. It made changing the oil filter a PIA as well.

I had asked this before too. RDM and I discussed this a bit. If you can find a shop that can make your lines for you and you didn't have a bearing turn on you, then its far more cheaper and beneficial for the simple fact you can build your lines and run them anywhere. I have access to the JIC parts and the hoses so my cost is nil. I'll price it out though, see what it would cost to build a kit to run lines like you and I talked about RDM, 50+ inches. Worth investigating at the very least.

As far as I am concerned the only advantage to DIY using the stock cooler as already noted is running the hose how you wish by creating your own lengths.

Monetarily the kits cannot be beat price wise, I DIYed because I get trade pricing and am also tooled up for this and I wanted to run the lines my way.

Kits are the way to go for a turn-key project and minimal time involvement, it's no real special magic to self fabrication, a matter of collecting time & parts vs. installing a kit,

As Kenny & Nobby indicate it's a wash for most of us to go the kit route, biggest cost for self fab is finding a shop that won't charge arm & leg to do a 1 time fabrication of a specialty hose.

It would take me over a day of running around trying to gather parts... This alone makes the KIT cheaper already. I can also GUARANTEE i'd need something else while covered in oil half way done the job when the hydraulic places are closed......

The Kit's are the way to go for me. I'm learning to press the EASY BUTTON when its offered.
