00:00:00.060 welcome to Banks unboxing where every 00:00:02.36000:00:02.370 day is Christmas today the UPS driver 00:00:06.01900:00:06.029 just dropped off a 2020 Duramax oil 00:00:10.54900:00:10.559 cooler hey it's Gail banks I've told the 00:00:21.76900:00:21.779 UPS man he's got to start wearing a 00:00:24.10900:00:24.119 Santa suit because this feels like 00:00:26.72000:00:26.730 Christmas I really enjoyed this let's 00:00:29.66000:00:29.670 have a look at what we've got here 00:00:31.70000:00:31.710 this is one of those boxes it's glued 00:00:33.92000:00:33.930 shut so I'm gonna try cutting it open on 00:00:37.10000:00:37.110 the opposite side so I don't have to rip 00:00:39.88900:00:39.899 through all the glue I may regret this I 00:00:44.74000:00:44.750 think we need a new alright we're 00:00:51.43900:00:51.449 getting a new we're getting a new knife 00:00:53.63000:00:53.640 guys oh Lord 00:00:56.75000:00:56.760 oh okay we should be able to get into 00:01:02.29900:01:02.309 this baby here it comes this is what I 00:01:05.06000:01:05.070 was hoping for 00:01:06.14000:01:06.150 alright well inside the big box and we 00:01:15.62000:01:15.630 have a little box you never know the 00:01:20.63000:01:20.640 wisdom of all this gets it kind of 00:01:22.60900:01:22.619 escapes me but 00:01:28.94000:01:28.950 i I call that shipping air I fee takes 00:01:37.67000:01:37.680 up a lot of space in the truck you kind 00:01:40.28000:01:40.290 of wonder why they didn't just ship this 00:01:44.35000:01:44.360 come on baby I promise you guys next 00:01:47.93000:01:47.940 time 00:01:48.44000:01:48.450 that knife will have a new blade all 00:01:51.92000:01:51.930 right what have we got here okay this 00:01:59.77900:01:59.789 does not come with instructions you're 00:02:01.94000:02:01.950 supposed to know what to do with this 00:02:03.94000:02:03.950 and all right there's the baby we're 00:02:07.80900:02:07.819 looking for so what have they done new 00:02:11.69000:02:11.700 for 2020 on the dramatic oil cooler 00:02:14.00000:02:14.010 that's that's the question here and well 00:02:24.97900:02:24.989 I can tell you one thing right off the 00:02:26.39000:02:26.400 bat the filter mount Wow the filter 00:02:31.30900:02:31.319 mount is small the whole idea here is 00:02:35.33000:02:35.340 will this thing fit the earlier model 00:02:38.36000:02:38.370 trucks and we did a little research and 00:02:41.86000:02:41.870 the old 1 through 10 that BLB 7 lly lbz 00:02:49.55000:02:49.560 and lmm all use the same cooler oil 00:02:54.31900:02:54.329 filter assembly then you move into and 00:02:58.63000:02:58.640 we've got that example this is the early 00:03:03.50000:03:03.510 l5p and this is the 2020 l5p so for 2020 00:03:10.90000:03:10.910 they've operated the maximum towing 00:03:13.64000:03:13.650 capacity with the l5p engine something 00:03:17.09000:03:17.100 fierce so part of that is more radiator 00:03:22.97000:03:22.980 capacity I'm sure more fan I think the 00:03:26.66000:03:26.670 nose of the truck has more square inches 00:03:29.33000:03:29.340 of Inlet area for cooling air if you're 00:03:31.78900:03:31.799 going to run at rated power or close to 00:03:34.49000:03:34.500 rated power with a heavy load and just 00:03:36.83000:03:36.840 hold it there you're going to make some 00:03:39.74000:03:39.750 temperature you got to have adequate 00:03:42.29000:03:42.300 water pump fan radiator and adequate oil 00:03:47.78000:03:47.790 pump which they already have adequate 00:03:50.69000:03:50.700 oil cooler because oil is going to take 00:03:53.72000:03:53.730 a lot more heat rejection under 00:03:55.58000:03:55.590 sustained power for 2020 the horsepower 00:03:58.88000:03:58.890 remained the same and the torque peak 00:04:01.67000:04:01.680 went up five pound-feet so it wasn't a 00:04:03.98000:04:03.990 huge increase in power but there is a 00:04:08.15000:04:08.160 huge increase I believe and cooling the 00:04:11.30000:04:11.310 oil and I'm I'm really interested in 00:04:15.00900:04:15.019 retrofitting this pup to the earlier 00:04:17.99000:04:18.000 trucks so whoo looks like they went to a 00:04:23.87000:04:23.880 larger diameter bolt that's happy all 00:04:33.35000:04:33.360 right let's have a look at what we've 00:04:35.72000:04:35.730 got inside this pup right oh mercy okay 00:05:06.46000:05:06.470 what I'm looking for what I want to 00:05:08.84000:05:08.850 evaluate is two things 00:05:13.42000:05:13.430 oil temperature reduction through the 00:05:16.37000:05:16.380 cooler but also oil pressure reduction 00:05:20.81000:05:20.820 through the cooler so how do these 00:05:23.54000:05:23.550 things compare you would think that the 00:05:27.32000:05:27.330 bigger cooler would have less pressure 00:05:32.45000:05:32.460 drop but I'm noticing already that the 00:05:35.99000:05:36.000 plates on the 2020 appear to be a bit 00:05:39.74000:05:39.750 thinner but it looks like there's a lot 00:05:42.11000:05:42.120 more of them so the design change from 00:05:47.93000:05:47.940 19 to 20 is pretty obvious it looks like 00:05:55.00000:05:55.010 the same style of plate is used starting 00:05:59.54000:05:59.550 all the way back in o1 on the Elbe 00:06:01.64000:06:01.650 sevens 00:06:02.24000:06:02.250 and this early cooler has 11 plates the 00:06:08.15000:06:08.160 oil goes into this stack of plates 00:06:11.26000:06:11.270 through the plates and out and water 00:06:15.59000:06:15.600 flows through the housing from the 00:06:19.01000:06:19.020 entrance hole to the exit and through an 00:06:22.34000:06:22.350 elbow and up into the torque converter 00:06:25.43000:06:25.440 housing and then across the block in the 00:06:29.72000:06:29.730 back it enters right after the elbow it 00:06:32.81000:06:32.820 in or you know it enters on the left 00:06:34.88000:06:34.890 side and then it goes through a duct in 00:06:38.21000:06:38.220 the torque converter housing and enters 00:06:40.76000:06:40.770 on the right cylinder Bank in LML I 00:06:45.85000:06:45.860 don't have one so we're going to go 00:06:49.25000:06:49.260 right to 20 17 through 19 l5p 00:06:53.98000:06:53.990 same style and thicknesses might even be 00:06:58.13000:06:58.140 the same manufacturer of the cooling 00:07:01.61000:07:01.620 stack and this one I counted earlier and 00:07:05.66000:07:05.670 there's 14 of them 14 plates okay here's 00:07:10.61000:07:10.620 the 2020 l5p 00:07:13.81000:07:13.820 let's have a little count here I've 00:07:17.84000:07:17.850 counted the first plate as a cooling 00:07:20.90000:07:20.910 plate so I'll do the same thing here 1 2 00:07:24.92000:07:24.930 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 00:07:35.27000:07:35.280 19 so we've got 19 oil cooling plates on 00:07:42.35000:07:42.360 the 20 20 we have 14 plates on the 17 00:07:51.43000:07:51.440 2001 the oh 1 through 10 I'm looking at 00:07:56.36000:07:56.370 this and I'm seeing a big improvement 00:07:58.10000:07:58.110 guys the way the water leaves the 00:08:03.02000:08:03.030 housing to looks to be improved this 00:08:05.96000:08:05.970 thing is a monster by comparison 00:08:07.95900:08:07.969 the first thing we're going to have to 00:08:10.07000:08:10.080 confirm is that this thing fits in all 00:08:13.45900:08:13.469 the previous trucks without hitting 00:08:15.32000:08:15.330 anything else but it is readily apparent 00:08:20.14900:08:20.159 that the inlet looks to be identical 00:08:24.70900:08:24.719 just comparing the housing inlets and 00:08:27.64000:08:27.650 the location of the bolt holes yep yeah 00:08:34.00900:08:34.019 these look like they are identical where 00:08:37.25000:08:37.260 the water enters and I know this is hard 00:08:39.40900:08:39.419 to see I'll try to place it so you can 00:08:42.11000:08:42.120 see it well maybe there if you look in 00:08:45.11000:08:45.120 here as the water flows this looks 00:08:50.09000:08:50.100 promising 00:08:50.84000:08:50.850 but the actual opening into the earlier 00:08:53.32900:08:53.339 housing is much smaller so then it got 00:09:00.86000:09:00.870 better if you look at this one there is 00:09:05.12000:09:05.130 your opening but the entrance into the 00:09:07.46000:09:07.470 housing is much larger anyway you look 00:09:11.90000:09:11.910 at this it's much larger so better water 00:09:16.37000:09:16.380 flow into the housing but the exit out 00:09:20.60000:09:20.610 of the housing it's still close to the 00:09:24.80000:09:24.810 block so you what you've got is you've 00:09:26.54000:09:26.550 got plates up here above this point that 00:09:31.36000:09:31.370 don't really have good water flow 00:09:33.65000:09:33.660 through them that doesn't look too good 00:09:36.11000:09:36.120 to me on the 2020 they've moved the 00:09:41.21000:09:41.220 outlet up so the water has to flow from 00:09:46.31000:09:46.320 the entrance point through the assembly 00:09:49.40000:09:49.410 like this and it looks to me like 00:09:52.10000:09:52.110 they've probably configured the there we 00:09:56.99000:09:57.000 go the plates in such a manner as to 00:10:01.43000:10:01.440 take advantage of that and yeah they 00:10:03.47000:10:03.480 have all right boy this the 2020 oil 00:10:07.81900:10:07.829 cooler is looking awfully good nice open 00:10:11.71000:10:11.720 large Inlet as was on the earlier ones 00:10:14.88900:10:14.899 by that I mean the 17 through 19 00:10:18.00900:10:18.019 but the outlet is way improved 00:10:21.56000:10:21.570 so to use this on an earlier block we're 00:10:25.24900:10:25.259 going to have to have that 20/20 elbow 00:10:29.42000:10:29.430 and seal assembly as well it's going to 00:10:33.11000:10:33.120 be interesting now filter wise all the 00:10:36.59000:10:36.600 early ones all the way from oh one to 00:10:39.53000:10:39.540 nineteen use this filter which is a 22 a 00:10:44.93000:10:44.940 PF 22 32 AC Delco and this is the filter 00:10:50.05900:10:50.069 for the 2020 it's smaller so I'm I'm a 00:10:54.62000:10:54.630 little troubled about this I don't know 00:10:57.62000:10:57.630 quite what's going on here and I'm gonna 00:11:02.18000:11:02.190 look at some other internal things on in 00:11:05.36000:11:05.370 all three of these where they have check 00:11:08.32900:11:08.339 valves and where they don't have check 00:11:10.46000:11:10.470 valves the whole idea of the check 00:11:13.81900:11:13.829 valves is this if the if the cooler gets 00:11:17.87000:11:17.880 plugged and somehow restrictive and the 00:11:21.82900:11:21.839 pressure drop through the cooler goes a 00:11:23.93000:11:23.940 little too high the check valve opens 00:11:27.07900:11:27.089 and bypasses the cooler somewhat same 00:11:30.35000:11:30.360 with the filters on the earlier all the 00:11:32.50900:11:32.519 earlier ones up through nineteen they 00:11:37.30900:11:37.319 use a bypass filter so there's an 00:11:41.09000:11:41.100 internal bypass or check in the bypass 00:11:44.42000:11:44.430 check valve in the built into the filter 00:11:46.73000:11:46.740 and then they also have one built end to 00:11:52.30900:11:52.319 the oil cooler so there's two check 00:11:54.62000:11:54.630 valves in parallel why would you do that 00:11:57.97000:11:57.980 well they were worried that somebody 00:12:01.06900:12:01.079 might put on the incorrect oil filter 00:12:06.12900:12:06.139 one with no check valve then you'd have 00:12:09.62000:12:09.630 no bypass if the filter got plugged up 00:12:12.23000:12:12.240 it would choke off the flow to the 00:12:14.60000:12:14.610 bearings so they covered their tails on 00:12:20.19900:12:20.209 the 2020 there is no check valve 00:12:25.67000:12:25.680 secondary check valve I can see that 00:12:28.49000:12:28.500 right here and they've changed the 00:12:33.84000:12:33.850 the Mount and I don't I don't know if 00:12:37.44000:12:37.450 there's a non check valve filter made 00:12:40.41000:12:40.420 that would fit this configuration but I 00:12:45.38000:12:45.390 think they're thinking a little more 00:12:48.24000:12:48.250 modern like the guy who's changing his 00:12:50.85000:12:50.860 oil filter should know better I don't 00:12:54.84000:12:54.850 know but all I'm telling you is make 00:12:58.83000:12:58.840 sure you're using the proper oil filter 00:13:00.66000:13:00.670 on one of these I may want to look at 00:13:04.59000:13:04.600 how in the heck I get more more oil 00:13:07.74000:13:07.750 filter on this 20/20 assembly that 00:13:10.80000:13:10.810 remains to be seen 00:13:12.12000:13:12.130 bottom line is I want minimum pressure 00:13:15.24000:13:15.250 drop through the oil filter and minimum 00:13:17.55000:13:17.560 pressure drop through the cooler and I 00:13:19.65000:13:19.660 want maximum cooling of the oil now if 00:13:23.94000:13:23.950 you want to know how this all comes out 00:13:26.27000:13:26.280 follow along on our killing a Duramax 00:13:29.31000:13:29.320 series and we'll see how this 20 20 00:13:32.70000:13:32.710 stacks up against the 17 to 19 I'm 00:13:37.62000:13:37.630 loving these unboxing videos if you want 00:13:40.26000:13:40.270 to see more of these or are killing a 00:13:42.69000:13:42.700 Duramax series all you have to do
