Hey Michael, those filter adapters look familiar...do you sell those to Killerbee? I have the exact same one on my LB7...:confused:

No Brian.I buy them myself, but I also modify them to flow WAY more than what the adapter was made to flow in the first place. I want the full flow through it that the motor is capable of like it wasn't even there. I just like the one component to get the oil in and out that has the T stat in it to control these temps.

I think I might try to piece together the same kit Brian has, I might have to call you for pricing when I'm ready.

Would you mind sending me a PM on a price on a new adapter? Mine is cast, and has a small crack and leaks a little bit.

Piecing together a kit is good. However you will need to work with the air opening your truck has in the front. Some can be modded and some cant. It's useless to get a cooler that's WAY to big for the openings you have unless you cut or direct air flow to use it. In some cases I had to use 2 smaller coolers and feed from one to the other. At any rate, something is better than nothing even if it's small. However, one thing I know for sure and for certain. It's easy to drive oil temps in these trucks WAY over the safe area any time you add power in any way over the stock power. I flogged my LB7 one day up the hwy in a lower tune a few times (about 100hp over stock and truck had about 400lb in the bed in the form of a transfer tank and fuel). It was about 40 deg outside and I quickly saw the oil temp gauge (no coolers yet) go from 195 to 230 and still climbing fast. OUCH!!! Just my truck? Doubt it. I truly believe that the EGT and oil temp gauges are some of the most important gauges I have. All it takes is ONE time to cross the thresh hold of the oil break down temps to start the ugly wear process in the lubrication area. I think a LOT more folk have already crossed it many times and don't even know it. I do live at 6K elevation and this may also put more importance on the matter. However, I don't think that living at any lower elevation will make it a completely different story. Just sharing info on my findings and trying to help these trucks live a full problem free life.

Agree with that Michael, I saw 264* towing 6k 28' gooseneck, unloaded! I bought my LB7 with the fact that I knew it would overheat while towing, but looks like the gamble paid off for me, time will tell. I have a pic of the load I carried almost 1k miles in 30 hours.

Truck was 7500 and the trailer is right at 5k.

ouch! Long term at 260 or above is harmful. Brief excursions to 275 only cause partial break downs in most cases. I never recommend this any any case however. When mine would get to 245*, I would back out and let it cool down. This hasn't been a problem with the coolers though.

I did a curiosity test earlier today. I took out the adapter to the coolers today and plugged the lines to them (no oil flow to them or from them) and I took a run up to a place called Genesee which is just west of Denver on I-70. Its quite a ways up and about 6-8% grade up there. I put the truck in stock program mode and boogied up it watching EGTs and holding 75mph. The truck was unloaded and had nothing in it besides what comes stock and myself. It took my oil temps quickly from 185* at the bottom of the grade to 230* at the top where I exited off at Genesee and came back. The only thing I was thinking was "HOLY POOP BALLS". I can only imagine if I was pulling something (as I usually am) up the grades and going from west to east over the Eisenhower tunnel (the back side going from west to east is by far much longer and steeper) under power with 22K and on stock tune let alone ANY tune over the stock setting. I think about the days I did it before the coolers and cringe.

There is no oil temperature gauge in our trucks, but their should be. People assume their oil is the same temp as their coolant, but it's not. My oil always runs 10-15* warmer than coolant, even more towing. Ask yourself this; what temp does the fan come on at full lockup? 230*?? Wonder what the oil temp is, since the oil temp is what heats up the coolant; more than you think.

Michael, your findings are exactly why I tell people to tow on stock tuning, no matter what, hell my tune I pulled at truck to cali on is 1300 us on 30 overs.

Cooler is 4" thick, 7" high, and 28" long. Fits inbetween the front frame and bolts to the tow hook bolts, with L brackets.
