      Review & Installation Video

      Hey everyone I’m Justin with and I’m checking out a way to keep your ride cool, all while making a dramatic visual improvement under the hood as well, talking about these Mishimoto performance radiators for your Mustang. Mishimoto has become one of the industry leaders in terms of performance radiators, this direct factory replacement is a great solution for an old or leaking radiator. Now some of our customers have mentioned that this rad has been their cure for their motor running a little hot when adding different performance mods, especially superchargers which can notorious for making any motor run hot. This radiator has been designed to keep your street or strip Mustang much cooler thanks to their unique design, which allows a 25% increase of cooling capacity over your stock radiator. These radiators are manufactured from lightweight aluminum, feature leak proof brass fittings, and are all hand welded to ensure top notch quality, and a perfect fitment. On top of all that they also feature a limited lifetime warranty, no questions asked. The install may be slightly more difficult than bolting up that new cold air intake, but honestly it’s not that bad, think of it as a giant oil change. The first step is you need to drain all the coolant out of the factory radiator, but you want to make sure you have something large enough to hold all that fluid, we recommend at least a 15 quart drain pan. Once you’ve done that, yank the hoses off, then unbolt your factory radiator, removing it from your engine bay. Once you’ve done that, reinstall the Mishimoto in its place, reattach the hoses, and fill it with a 50-50 mix of coolant and water. That’s it, install should take you about 2 hours from start to finish. This would also be a good time to check out Mishimoto’s performance radiator hose kit, not only will they hold up to the heat and pressure better than your stock hoses, but they’ll also make a nice visual improvement under the hood. Every gearhead knows that heat is one of the worst enemies for performance, it can drain power, hurt your fuel mileage, or even damage your motor. So if you want to help your Mustang keep its cool whether it’s on the street or the track, then you’ll definitely want to check out these performance radiators from Mishimoto

        Badass aftermarket part

        My stock radiator in my 05 gt had a coolant drip that I recently noticed when changing the oil, it wasn't near the hoses so I assumed the thing must be cracked.. oh well, an excuse to upgrade! This thing looks great out of the box, shiny aluminum body with a cool M printed on one side, my buddy and I installed it out of the garage at home, we did it the stupid way so it took us little longer should only be 2 to 3 hours depending on what tools you have available. Everything lines up and fits perfectly with the stock 05 fan and heat lines, no modifications required. It was easier to put the new part in than it was to remove the original.. car still stays at the same temp as before, around 195 F, I used zerex valvoline g05 coolant, orange in color, it's been in for about half a day now all good so far. Remember to tighten the drain plug on the new radiator it comes pretty loosely on there. Great buy worth the price

        Great radiator

        While the first radiator I received had a stripped plug hole, I contacted Mishimoto and they did replace it. The car never gets hot. It doesn't interfere with the AC being on anymore. Great product.

        Snug Fit

        Is a snug fit with no issues getting in. The AC condenser bottom holes did not line up to well so they did need to be enlarged. The top holes were perfect. Also the air box tube that runs to the front of the car has a mid section that did not fit due to the size of the end tanks. that part pops off but all other pieces fit with no issues.

        Added to Vortech Supercharged Mustang

        Just put this radiator on my Vortech Super Charged mustang. I complimented it with the Ford Racing GT 500 fan. After a night of spirited driving, power stayed consistent and peppy and I did not notice any power being pulled due to heat.

        excellent mod for your Mustang

        I had the Mishimoto radiator installed. Sorry, no longer a gear head, can't tinker with my car in my development; HOA Rules. I was very happy with the install, it took them an hour and a half. That included the removal of the old one. Wish I could have watched them do the work. My car is running noticeably cooler. Unfortunately, I can't tell you the exact difference as my Temp gauge doesn't have any numbers. I haven't checked the extra HP yet. I have a couple additional projects, plus I added a cold air intake and dual exhaust.

        Great Product

        So far so good its been a great product. Very clean and solid built. Too early to tell performance gains but the look is great and the install was simple. I would say an afternoon for install only due to the disassembly portion of the vehicle.

      5 Top Rated Questions

      Does this radiator require more coolant than the stock one?

      • Yes, this radiator is slightly larger than the factory style currently in the car, it would be recommended to add and check until the DEGAS bottle for the radiator fill is to the full mark with the car hot and cooling system bled.

      does this work with the factory fans? Reuses the factory hoses? I havent seen these questions answered by someone who has bought so I was hoping the company selling them would list this.....

      • The Mishimoto Performance Aluminum Radiator - Manual (05-14 GT, V6) will work with your factory hoses and the factory fan.

      Helpful (3)

      Can you use this with stock radiator hoses?

      • The stock hoses will fit with the Mishimoto Performance Aluminum Radiator, however, since the Mishimoto Radiator is slightly thicker, it will push the stock hose back just a bit.

      Helpful (2)

      This says it is for manual transmissions. Will it not fit an automatic too, assuming it should not matter?

      • This radiator is designed specifically for manual transmissions only. Mishimoto offers a universal radiator that can be used for automatic transmissions.

      I have an 06 Saleen S281 with a turbo kit, will this fit even with the front mount intercooler?

      • Unfortunately we have not tested this radiator with that setup, so we would be unable to guarantee fitment.
