Would you mind posting some pictures, parts list and prices... how many beers and swearing did it take? Thanks
Haha no beers, I started working on it at 9am.
I used a Hayden 1677 plate and fin style (listed as full size car GVW 14,000lbs and 2,500lbs towing, my box said GVW 20,000), its larger than the Mazda really needed but the price difference was minimal and I like going over the top just a bit.
Sorry no pictures, my phone is in my pocket and my hands are always dirty.
The install was pretty easy though, the kit had the brackets bolts lock washers and the Mazda radiator support actually has a bunch of unused threaded holes! along the bottom that aligned perfectly, I found out that the belly pan bolts matched the threads and worked great, for some reason I had a few extra laying around in my box from other cars.
Here is a list of what I bought:
Hayden 1677
1 barb to barb 3/8"
4ft of 11/32" ID trans hose (I guess this is a pretty standard size for auto trans)
1 size 3 hose clamp (kit comes with 4 but u need 5 because of the barb)
Also two bolts that match the threads of the belly pan bolts (not the ones that screw into the bumper but the ones that bolt to the bottom of the rad support)
How to do it:
Remove front bumper and belly pan or at least the bumper and the front part of the belly pan (no idea why people are scared to do this its easy and very light)
Test fit the aftermarket oil cooler to the rad support
Connect your hoses to the aftermarket cooler
Bolt aftermarket oil cooler to rad support final fit
Run lines to the factory oil cooler, make sure the lines don't go lower than the bottom of rad support (the car is already low if you run it lower than the rad support you might risk the chance of damaging the aftermarket cooler lines if you run up on a curb).
Connect the hoses from aftermarket cooler to factory cooler (tip: the hose that is on the drivers side is the one that returns to the trans so this is the one you want to run through the aftermarket cooler, always best to use the factory cooler first then run it through the aftermarket cooler then back to the trans)
Zip tie as needed (use quality zip ties no harbor freight crap) to prevent the hoses from rubbing on anything.
Start up the 5 and let idle, check to make sure aftermarket cooler is getting warm, check for leaks
Top off fluid
Done!
Sit back and be happy you just helped your 5 live longer or at least helped your fluid last longer.
