    • It looks good
It looks good and should work but I order the wrong one and had to return it. So all I can say is it looks like it will work for the right car.

    • Hayden 403 cooler installed on 1997 Mazda 626LX 2.0L 4 cylinder
I had a very alarming incident that I attributed to a transmission problem recently (not at all sure I could make it home) and my online investigation revealed that my car (and other Mazda 1993-2002 626's, and probably some others) were given a Ford CD4E transmission that was designed for significantly lighter cars. The early failure rate of that transmission in these Mazdas (mine is 3800 lb), is quite high. One Mazda technician told me that among those in the know, it's called the 60k transmission. Mazda issued a couple of bulletins around 2000 indicating that an external transmission fluid cooler was recommended, however it was to be done on the customer's dime. I decided to DIY it. I think that Hayden should have supplied at least another foot of hose. The return line from the cooler to the transmission that was already there (coming previously from the radiator), was barely long enough to reach the cooler. 1 inch less and it would not have reached. If it had not reached, the ~4 foot length of hose supplied in the kit may have been barely enough, when cut to produce the two necessary connections (the first being from the radiator's transmission fluid outlet to the cooler's input, the second being from the cooler's output back to the transmission), maybe not. Hayden in the instructions indicates two possibilities: Series (your fluid first goes through it's former cooling, being through your radiator) Separate (you bypass the radiator for whatever reason, presumably because your radiator has a problem) I did series, the recommended method. I finished the install yesterday, and I made the job harder than necessary. I'll explain. Firstly, I opted not to the install as suggested in the included instructions. They have 3 suggested placements: 1. In front of the AC condensor, which is in front of the radiator 2. Between the AC Condensor and the radiator 3. Behind the radiator. #1 is recommended because it affords the most efficient cooling, and that is what I opted to do. However, before I installed I was guided to a thread that shows an installation including diagrams and photographs: [mazda626 dot net/topic/24936-external-trans-cooler/?p=352865] The thread shows a method utilizing homemade brackets that stand off the cooler from the AC condensor, generating better air flow to both the cooler and the AC condensor. I decided I liked that approach. However I made some mistakes, and only realized it after committing to them. I succeeded in finishing the install in a satisfactory manner, however if you do this or something similar I have a few suggestions: 1. Assemble the cooler to the brackets before mounting the assembly to the vehicle. 2. Affix the hoses to the cooler next. 3. Only then, mount the assembly to the vehicle. Doing things in that order will make the installation far easier than the way I did it. Now, the way I did it took incredibly longer than the "average 1/2 hour" that the instructions indicated. Of course, if you make your own brackets, it's going to take you a lot longer too, but if you do things in the order I indicate and don't run into problems it shouldn't be too tough. Safety first! ... show more

    • Recommended but those hoses would not slide on easily.
So far so good. Great kit for the price, it used an odd transmission gates hose diameter, 11/32", and wasn't long enough for my 14' Nissan Rogue Select for both legs. By the time I figured it out I had to go to the auto parts store and they only carried 5/16" diameter which is only 1/32" difference so should feasibly work. Well getting the 11/32" hose was challenging enough having to grease the barb attachment with motor oil and using a heat gun to make the hose more pliable since it was 60 degrees out but it wasn't freezing by any means. When I moved to the 5/16" hose, boy was it difficult to insert and I bent some of the aluminum fins on the cooler since I was getting desperate to get my vehicle back to service; being my only mode of transportation. Luckily the fins aren't brittle and I was able to get them straight-ish, bending each fin one by one with a small flathead screwdriver. Definitely recommend buying the 11/32" gates hose if you think you need more than the 4'. ... show more
