Hayden Aluminum Automotive 403 Ultra-Cool Tube and Fin Transmission Cooler

A new cooler and a radiator for any Nissan Sentra CVT transmission is a must if you plan on keeping in a long time I put pictures on here looks like they went away my 2017 Nissan Sentra S 1.8 L It only came with a cooler that has two prongs coming out of it for cooling the CVT transmission I bought one has four and added the cooler radiator this made a world of difference it’s a must before doing this the car that has only 30,000 miles on it still like brand new when you get to 75 miles an hour it felt like you couldn’t go faster after I install those two parts car runs like it should. You also need to replace the CVT transmission fluid every 35 to 40,000 miles this means a new round filter under the driver tire and a new pan filter in your transmission pan this car takes about 9 quarts of CBT oil but you add three at a time drain itPut three back in start it put your brakes on and go through all the gears really slow five seconds each gear repeat the process drain put 3 quarts in to you equal 9 quarts there’s a video on YouTube explain this better that’s my experience with my Nissan besides that thank it’s gonna be a good car now

Great transmission cooler. Have had it on now for a few days I took it upon my self to see fluid temp difference. Before trans fluid after a good 30 min drive be hot now its luke warm. I am using this on my 2003 nissan sentra 1.8 automatic. Everything in boxed worked great. Clamps are good but are a pain to tightned down but for the peice I cant complain. Also if you bend a fin dont stress simply use a straight screw driver and bend ot back close as form as possible wont hurt it any.

Easy to install, with kit provided plus one brass splicer from Lowes. I painted mine black so it wasn't so noticeable behind the front grill. No leaks the first time out.

Works

Install took about 30 min on a 2004 Grand Cherokee with the 4.7 non-HO and the 545rfe trans. I used fuel clamps in lieu of the included worm gear clamps, as they are a more positive grip without cutting into the hose if you were to over tighten them. I also used a 6AN fiberglass braid covered poly line, mostly because it looks better. However, having included my upgrades, you can still buy with confidence and use what the kit supplies. I have installed several Hayden coolers over the years with what was in the kit without issue. Techtip: If your vehicle has a factory tow package, it likely already has a cooler in your radiator. Assuming that doesn't have a leak, it is generally recommended that you still use the factory cooler in conjunction with the aux Hayden cooler to prevent over cooling. A lot of trannys are designed to run at a certain temp - over cooling, especially in winter, may prevent your trans from shifting into overdrive(s) thus killing your MPG. From trans: to factory cooler, then aux cooler, then return to trans. Also, if you are mounting with the in/outlets horizontal, be sure and use the lower connection as the inlet. This ensures the entire cooler fills without air. If you use the top as the inlet, you can get a "waterfall" effect, filling cooler capacity with air and reducing its efficiency. You can install vertical as well, but in that case be sure and put the in/oulets on the top to prevent the same effect.

Easy to install, keeps the temperature lower, no leaks no issues on my order, buy about extra 3 ft of hose though dont stretch it or kink it

Going on 6 years strong, this is and has been very benefitting for my Jeep XJ!

Rock put a hole through mine and it fit perfectly in my escape durable feeling works perfect. Great price l
