Installing an additional radiator for the automatic transmission - 6 in the Hyundai Tucson 4 New
Hello, fellow motorists!
This video is for all owners of new KIA - Hyundai vehicles (with gasoline and diesel engines, hybrids, and 6-8 automatic transmissions), as well as interested parties, service stations, and authorized KIA - Hyundai dealers.
In this video, we'll show you how to install an additional KIA - Hyundai automatic transmission oil cooler (original part number: 254603E900) and explain how it works.
To avoid repeating the information about the parts needed to install a radiator, see my previous post: https://www.drive2.ru/l/6157089204422...
For those unfamiliar, here's a similar job I did on my previous car five years ago: https://drive2.ru/l/509635460297917558/
I personally get similar jobs done in Kyiv at the Premium Service service station with Vitaly Aleksandrovich. The mechanics at this company have extensive experience installing similar parts in various cars, and they have no issues with the quality of their work.
We hope that after watching the video, you'll be able to repeat this job yourself or at a specialized service station.
I'd also like to remind everyone that our official Hyundai dealers are ready to perform similar jobs (we spoke with Eden Auto); they are aware of the problem and can help with radiator installation (all labor and materials are at your expense).
Now for the technical details:
1. To install the radiator, you need to remove the bumper. It's simple and straightforward, with no complications or special features. There are no disassembly fasteners in the bumper or body. There are plenty of instructions and photos online. Disassembly begins with partially removing the plastic side trims around the front fenders; you don't need to remove them completely. Everything is secured with clips and latches; use plastic pullers for this job.
2. Next, you need to make brackets for the radiator. We used ready-made construction brackets made of 2.5 mm galvanized steel, but you can use any other type, depending on your taste and preferences.
3. To attach the radiator to the bumper, drill two holes in the upper end of the metal reinforcement and install riveted nuts. You can also rivet the radiator, but this is less secure. 4. The supply and return hoses are about 2.5 meters long. The hoses, in their protective braiding, fit perfectly inside the bumper reinforcement cavity. It's not visible in the photo, but there are stiffening ribs and some space inside the reinforcement.
5. A pair of hoses can be secured to the front bumper reinforcement using another fastener—an angle bracket that attaches to the standard stud of the bumper reinforcement and points downward. You can also secure the hoses with clamps, but that's not our method and isn't aesthetically pleasing!
6. We painted all the fasteners black, and treated the bolts and nuts with Dinitrol anti-corrosion compound.
7. We also found some paint abrasions on the reinforcement from the plastic center guides of the bumper, so we applied a couple of pieces of sound-deadening material to the contact points to protect against friction and corrosion. 8. After installing and connecting the radiator, our oil cooling system capacity has increased, so don't forget to top up the automatic transmission with ATF SP-4.
We used almost 1 liter, meaning the cooling system capacity has increased by almost 1 liter.
After that, we put the bumper back on and use the automatic transmission, which is not afraid of two-hour city traffic jams in first gear, trailers, heavy off-road loads, mountainous terrain, and summer heat.
As a reminder, our radiator is located immediately after the outlet of the automatic transmission (red mark), then connected in series to the input of the standard heat exchanger.
This creates a sequential connection system: the first is the additional radiator, the second is the standard heat exchanger.
We tested the new cooling system in various modes and are very pleased with the results. In two-hour traffic jams while driving in first and second gear, the automatic transmission oil no longer overheats (previously, it reached 123 degrees Celsius; it should be no more than 95 degrees Celsius). The automatic transmission operates smoothly, the oil and clutches don't burn, and there are no jerks or delays when shifting.
The transmission shifts smoother and smoother, which is especially noticeable in the city after long traffic jams.
We monitor engine and automatic transmission temperatures in the vehicle's on-board computer via an OBD port connection or with a computer at authorized dealerships. You can also check the temperature using the free Car Scanner Pro program and an ELM 327 Wi-Fi or Bluetooth OBD adapter.
Here's my D2 logbook, which contains a wealth of information and photos of temperature readings: https://www.drive2.ru/r/hyundai/tucso... Various people also have similar readings on Hyundai forums in the CIS.
That's all for now. If you have any questions, please let us know and we'll a...
