My factory lines and hard lines. They have a fuel line style clip on them.

 

I wanted to do a oil cooler also but could not find any oil output or input on the block. Didn't really dig deep into it.

They make a nipple that goes from the factory quick connects to a hose barb, I actually bought two; one was a Derale.

If it is a gas engine, it is by the oil filter.

Yea it's the 6.0. I'm doing a oil change in a few days I'll have to look for it. Thanks.

Great that adapter is what I need. I'll probably just do all black AN lines.

You can do solid runs so the only crimps are at the fittings. No metal to rubber. Take your measurements, go to a local hydraulic shop and have them made or order them. For my particular cooler I needed 2 ea. female -12 to male -6 AN adapters and 1 ea 1/2" NPT plug. On the tranny, the 4L60E took what I believe is a 1/4" NPT male to -6 AN male adapter. needed 2 of them. I do not remember what adapter for the radiator.

Got around to installing the replacement cooler today (Long LPD 28k gvw). It is a lot heavier, thicker, and just overall better built than the flexilite.

 

I used two pieces of flat aluminum strap to span from the right grill support to the center grill support. These are the supports that the grill snaps into. Had to put slight bends in the ends to hook in nice, essentially made zee bars. They ended up almost exactly the correct width, within 1/8", and made for a nice ridged mount.

 

My hoses were already long enough. Took about three hours overall from start to test drive. Initial impression, temps topped out at 118*F with ambient air temps around 60*F. That's probably a 20*F drop over the Flexilite. The one thing I noticed is that the temperature fluctuates more than previously.

Question. What is the preset thermostat in the trans? I know the torque converter won't lock until it's 70*F. The reason I ask is that I get about 120*F regardless of the ambient air temperature until it gets over 70*F, then it gets to about 130-135*F...

Towing around 5000#s, I topped out at 145F with temps near 60F and pulling in the mountains (of Pennsylvania). That was a 300ish mile trip. I'm pleased with that....

Where did you find the fittings from? I have the 6l90 and cant seem to find the fitting size. I found a cooler with an fittings, so I would just need to have a an line made to length then get the right adapters.

      I have thought an EV might have some practical value in extending the life of the ICE members of ones fleet. Now....I'm convinced of it. I've been letting my better half access Raven (Mitsubishi Mirage) for her needs while Dizzy has been in the shop. Being the fuel freak I am and given the fact Raven is capable of over 60 mpg in clean air on a warm day I was taken back by the wife's ability to take a car that had used a half a tank of gas that to that point had returned a value of 57 mpg and return in with a decimating 51 mpg for that same tank in that same day in a 15 mile round trip of short hop errands and a stop in the drive through at Micky D's.  😱   Trust me on this. It would take the remainder of that tank driven on the highway to return that tank to just 54 mpg. This is not a Mitsubishi issue. This is an ICE issue that is magnified in vehicles capable of such high fuel economy values. On a percentage basis your 1500 does the same thing. Short hopping an ICE consumes a good deal more fuel and in doing so provides zero additional useable outputs. That entire volume of fuel is wasted in diluting the cylinder walls oil films, creating crankcase moisture and acid content and the resultant wear.    Enter the SLATE. All of that is avoided and the ICE's advantage in range and made useful at reduced wear for your ICE!   Kind'a cool.

      Back in the day people would buy cars based on performance. The charger posted does 0-60 in 3.3 seconds. And it’s fully loaded.  It has a decent warranty and will fit most anyone’s needs. Remember the original Hemi? 90 day warranty. 25K mini truck or that car? I’d go with the car. It wouldn’t fit my perimeter. If I could just talk my wife out of her Genesis. It would be perfect for her.

      Let's pivot this back. Someone said they wanted pictures.   Even better, there's already video. Pre-prod prototypes are already on the road and they're letting the press drive them.   JerryRigEverything did a good review. I really enjoy his content and EV adventures, so I was thrilled when he had the chance to review a Slate:

      Interesting pivot.

      The Charger EV was stillborn. Wrong car at the wrong price for Dodge's intended audience. Now at a good price with fire-sale discounts, and still not selling, it's still very much the wrong car. Again, Dodge's intended audience. I believe a lot of Stellantis' EV blunders were all under Tavares' regime at Stellantis...the board convinced him to move on. Neat car, just wasn't received on the level that would sustain mass production.   Dodge is headed in a better direction for its core business. I didn't think there was anything left to get excited about re: the Durango after its 15 year run, but they're just now releasing a 392 version that should price out in the low 40's. Nicely done. I'm not sure I would touch anything Stellantis makes with a 10' pole these days, but the Durango is still mostly parts designed like 3 parent companies ago so maybe it's still OK?
