Best Truck Engine Oil Coolers

just one problem the sandwich adapter will not fit on a 2008 Avalanche 4x4 the front drive shaft is in the way had to modify

Before I purchased this oil cooler, I was pulling my small boat loaded with camping gear over the willamette pass in oregon in the middle of summer. The temp outside was pushing 100 degrees and the road was a pretty steep grade uphill. My ram 1500 started singing with different bells and displayed engine temp was pushing 245 degrees. I started sweating bullets, hoping my engine wouldn’t blow up. After I got home I did some research and found this oil cooler. Hoping it would help and do the trick, I purchased it and hoped for the best. We went camping this year to the same location, and the entire way I was staring at all the temp gauges. My truck never got above 220 degrees. This thing works!

Installed the Derale engine oil cooler today. Excellent kit installed without any problems. Parts were very complete. I am pleased with the proiduct.

I bought this engine oil cooler so I could pull my 21 foot boat with my 2016 Ford Explorer. I am very pleased with how it works. It was easy to install even with having to remove the bumper cover so I could attach it to the front of the radiator. I would buy another one if I ever needed to. I would also buy from etrailer again, they have great prices and products.

Installed this product on my 2013 Ram 5.7 Hemi. Install was simple and straight forward. I hoped there would be improvements in the operating temperature of my engine oil, which there was. Now towing my trailer is no worry about engine oil temp. This cooler works exactly as advertised, and the temp never go above 220. An unexpected result was better gas mileage by almost 2 additional miles per gallon. Also the truck runs much quieter than before and smoother. This noticed by my wife who rides with me always. So I would defiantly call this a win win install and purchase.

I purchased this kit 1 year ago for an 08 Toyota Highlander V6 Sport. The vehicle had a small (and I mean small) trans cooler already installed with the sport, but adding this additional cooler gives us the piece of mind an confidence that when either towing or evening just sitting in temps up to 116F at the drive through in SoCal during summer hours, my family will stay cool. The fans run less and the whole vehicle runs a bit cooler as well. I have verified this with 3rd party OBD readers, actively watching oil temps both at normal operating temps, hill climbs, towing, and when sitting in extreme heat. IT DOESNT BUDGE! I dont have enough good things to say about this cooler. If youve ever thought about it, you should do it. Very easy to install and it flat out works.

It has been 1 year now. Here is the story. Dodge Ram 1500 5.7 w/3.92 gears. Oil temp at speed with no trailer: 224 Oil temp at speed with Springdale Mini RV: 240 (backed off at that point….it would have kept climbing) After the install: Oil temp at speed with no trailer: 200ish. With trailer 210-220 Before I did this, I had to keep it at 55 in the expressway to keep my oil from turning into charcoal. Now I can drive normally. Only at the hottest part of the summer on a long grade did I ever brake 230 and it cooled right back off at the top of the hill. Also holds about another quart of fluid which I like from a wear/tear perspective. Even if the temp wasn’t an issue this kit would be worth it to move the oil filter to a non-retarded spot. I opted to go with the frame on the right side. Can change filter from side if wheel is turned. Very nice.

My vehicle is a 2010 Ram 1500 5.7 Hemi 4x4. Overall product is great, those Conti hoses are awesome and little hard to get on lol but only issue I had I couldn’t retain my factory mopar oil filter which isn’t a big deal I got a WIX filter that fit. Thanks for quick shipping and great product! Will be buying a transmission cooler from you soon!

Love my engine oil cooler. I was having overheating problems with my Dodge truck while towing on a hot day. I asked the guys at etrailer if I should add a bigger radiator, and engine oil cooler or another tranny cooler. They nailed it when they recommended a supplemental engine oil cooler. I now can town my fifth wheel RV trailer on the hottest days and in the mountains without overheating. I do still have to watch the temps and if they start to get over 260 f or so I downshift a gear or two to get greater fluid flows. The only reason I am not giving this 5 stars is that with the supplied hose clamps I was plagued with constant slow leaks. I finally bought a much higher end hose Clamp which did solve the problem.

I was surprised at the lack of feedback on these products, and the differences in opinions. I tow a fare amount, between 7000lbs and 9500lbs. My vehicle is a 2013 Dodge Ram 1500 with the 8 speed transmission. ( outside temperature 20-30 deg Celsius ). Before I installed this engine cooler my temperature ran around 115 deg Celsius on a flat pull and 130 - 135 deg Celsius on most hills. After a hill it took a long time to drop in temperature, most time it hardly dropped. Now I rarely see 115 deg Celsius on a hill, and recovers to 100 deg Celsius very quickly. So in short I'm very happy with this product. I would recommend it to anyone that Tows.

2009 GMC Yukon XL towing a 7,800lb travel trailer from California to South Carolina..... I don't believe the Yukon would have made this journey if it wasn't for the oil cooler and additional -to the stock- transmission cooler. Dragging the travel trailer through the mountains during the heat of the summer was taxing. However, my engine temp barely went past the 12 o'clock position and transmission never got above 190 F. Before installing these my engine temp would go to the 1-2 o'clock position and transmission temp would get up to 210 F. Highly recommend this product. Just make sure you have a filter that fits the adapter before installing. Just take the adapter to the auto parts store and find one that spins on it.

1 day early shipping, and excellent products, will use again

This is a good cooler however on a 4 wheel drive avalanche it's a challenge to get it installed in a position that will work with all of that equipment under there. I pinched the oring a little bit and it's leaking very slightly. On the next oil change I'll replace the oring, other than that this cooler works great.

Save your money. Two big problems. First, the sandwich plate adapter continues to work loose causeing an oil leak. I've removed the filter and retourqed to Derale specs a couple of times and it eash time after a couple of days it starts to leak again. Derale tech support was not at all helpful, they said, hmmmm, maybe tighen it a litte more, which I did, and it didn't help. Second issue is this cooler is very small, I installed it on a Ram 1500 5.7l and it made no noticable difference in the engine oil tempure when towing. I considered buying a larger cooler core and asked Derale tech support for some sizing guidance and their best response was put as big a one as will fit. Lot of science going on there. Couldn't give me any information regarding input and output temps vs flow, sizeing guidelines by displacement, nothing, no data of any kind seemed available. I'll make one more attempt to reseal, retighten, try a new o-ring etc. It doesn't work it's coming off and going in the trash. Overall the kit is sized for a very, very small application, maybe your riding lawn mower, that should be indicated. On a full size 1/2ton pickup this does next to nothing for your oil temp. Unfortunately tech support from Derale was no help whatsoever and showed not interest in helping trouble shoot or solve the problem. Very disappointing, I'd look else where.

Happy to find a system with the adapter. Mounted to my 4runner very easily. Not much confidence in the plastic mounting method will make something else.

This is a quality product and performs great. Installed on a 2012 Toyota Tacoma and had to have some machine work accomplished and a change from the original oil filter. Installation was straight forward after those issues were resolved.

just what i needed easy install nice quality
