Review on Hayden Automotive 678 Rapid-Cool 🔥 Transmission Cooler with Plate and Fin Design by Nathan Guzman

Good quality product installed on a 2011 Acura MDX. I followed the MDX installation video guide provided by a well-known internet trailer company, but they used a different manufacturer's transmission cooler. I used the Hayden because I put the Hayden in my last car and drove it thousands of miles with no problems, plus it was a lot cheaper and virtually identical. A few pointers for those looking to fit a Hayden 678 on a 2nd gen MDX (probably applies to the Honda Pilot as well, but not sure): - When I fitted the supplied hose to the radiator hose nozzles, the first one slipped easily, but the second was a struggle, even with silicone grease. I struggled with this for about 30 minutes and still couldn't shut it down completely. I ended up cutting about 3 inches off the tubing and then it slid perfectly. I inspected the inside of the cut section and it had no defects. I can't understand why I had such problems. - As in the video I mentioned, you can do this installation without removing the front bumper/fairing by bolting the radiator to the existing transmission oil cooler bracket, but the Hayden radiator flange isn't wide enough. You need to make some metal tabs to increase the width of the flange. - Just like in the video, I secured the right side with one of the plastic cable ties that came with it. - You will need to remove the plastic skid plate/cover just behind the bottom of the front bumper. to access the transmission lines. I also had to lift the front of the car and put it on jack stands to get some room to maneuver with my hands. with three screws on 17. I removed the two front ones and unbolted one rear one and turned the bracket to the side. Unless you have very small hands and/or a lift I don't see how you can get the job done without moving this mount, but in the video it kinda does. There is also a small hose that I used to unclip the 2 white clips from the car frame so I could move it around a bit. I was worried the hose wouldn't be enough, but it was about 9 inches taller than you actually are. need mdx. Just be careful where you cut so you don't cut off an end. I used some anvil pruners and they cut well. - On my 2011 return line (and video), the canister filter line was about 6 inches from the metal tip. Confirm this by starting the engine, shifting gears, then turning off the car and feeling the two hoses. The radiator hose is the one you will tie to. Slipping of the hoses leads to the loss of transmission oil. I probably spilled about 1/8 liter in the process. Having one more person with you might help, but the scope of the work is so narrow I can't imagine it would help much. I slipped the new hose over the newly exposed metal bar and then connected the old hose to another piece of the new hose using Hayden's flared aluminum tubing and 2 hose clamps. Before switching, make sure there are clamps on the hoses. You will also need an extra hose clamp for this installation method. When I started the car to check for leaks everything was fine except a couple of tiny bubbles appeared on one of the connections on the flared aluminum tube. I think the Acura's hoses are about 1/16" wider than the 11/32" hose Hayden suggests. I tightened the clamp and the bubbles disappeared. Keep in mind that not only do you NEED to replace the spilled gear oil, you also need to add some more since there is now more capacity thanks to the new coolant and hoses. At the beginning I refilled about 200 milliliters and will check after 15 minutes of driving and refill if necessary. Adding transmission oil to the MDX is a little fiddly - you either need a funnel with a long, flexible hose to fill through the dipstick, or you have to open the filler hole on the transmission, which requires a long socket extension and some brute force. I hope this helps someone!
