Review & Install 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

Keep Cool. Keep temperatures down to keep producing maximum horsepower whether it's on the street or the track with a Mishimoto Aluminum Radiator. When you're running your Mustang hard, engine temps can spiral out of control, draining precious power and even causing engine damage. A Mishimoto Mustang radiator has up to 25% more cooling capacity than your stock radiator to keep things cool and running right.

Lightweight Aluminum. Mishimoto Radiators are crafted of lightweight high-quality aluminum. Each radiator is hand-welded to which ensure a perfect fit and great underhood appearance.

Leak-Proof Design. Other aftermarket radiators have a design problem that causes leakage from the outlet to the overflow reservoir. Unlike other manufacturers, Mishimoto uses specially designed brass fittings to ensure leak-free performance. And all of their radiators are pressure tested twice before leaving the factory so you can install your new radiator with confidence.

AmericanMuscle Recommends. This radiator is a perfect combination with Mishimoto's Silicone Radiator hose kit for your 2005-2012. (Add on option above.)

Application. This Mishimoto Mustang Radiator is designed for 2005-2014 V6 & GT, 2008-2009 Bullitt, 2007-2008 Shelby GT with manual transmission. Does not fit the Shelby GT500.

Mishimoto's "No Questions Asked" Limited Lifetime Warranty

Technical Note. If you have an automatic transmission, you would need to purchase the required Mishimoto Transmission Cooler from the drop-down ordering options above. May require custom work for proper installation.

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 (1)

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.

Will this radiator fit with the 2013 gt500 fan upgrade on my Gt?


  • This Mishimoto Performance Aluminum Radiator was designed to work with GT's and V6's with the factory fans. The use of the GT500 fan from a 2013 may cause some fitment complications and may require some trimming and modification for proper fitment.

    Not Happy with Product

    Bought one of these in spring 2009. Made it through the Summer, then it started to leak from the welds on the side. Mishimoto replaced it and recommended using their upper mounts, which they supplied at no cost. Seemed to hold up until Summer 2010 when it started to leak from the side welds again. I won't bother with another replacement from Mishimoto as obviously the weld quality is terrible.

    Radiator works like a charm!

    I ordered this radiator for the hot Georgia summers and had it installed withing a day. Removing the old radiator and installing this one is only a matter of disconnecting the hoses and unscrewing a few bolts here and there. All in all a great fit and works well. Heres a tip though: Do NOT get the Mishimoto transmission cooler unless you really need it. The new radiator has fittings for the original cooler to drop right into the same place! The performance transmission cooler is awful to connect to the original hoses so use the original!

    Great new addition to my 07 AUTO

    Got this late last year. NOTE: This WILL fit auto Mustangs!!! You simply reuse the stock auto tranny cooler. It simply unbolts from the old one and bolts onto this one using the same 2 fasteners. Great product. Looks Great under the hood. It's more than twice the width of the stock rad which I had to replace after running over a small boulder :*( BUT, it was a great opportunity to upgrade this part with something that'll give me piece of mind knowing my motor has increased cooling capacity. Install was a sinch (my 1st time with a rad swap).

    Mishimoto Performance Aluminum Radiator

    Put this on my 2007 V6 which ran over a boulder and turned my old radiator into a bent V. This is quite the quality product!!! Fantastic build with quality welds all around. The stock fan/shroud, auto trans cooler, and A/C condenser fit perfectly and the entire assembly basically bolted itself back into the car. Now I'll never have to worry about overheating again as this radiator is like just over twice the physical thickness as the stock unit. AND it looks great under the hood :D

    Cheap, effective, but PITA to install

    It looks great and I was pumped to get this thing installed until I actually did it. There is no installation instructions, just a pamphlet in the box that says "Go to our website for install instruction videos". The only videos there were for 94-95 and up to 2004. OK, no big deal its not rocket science its a radiator. Unfortunately though the welds seemed to be quality, the person who welded it there so well wasnt look at it straight because neither were the stud/screw holes. We had to take a rubber mallet and gingerly straighten their work. Then we try and fit it to the AC condenser, no bueno. The mounting holes were considerably off. After some time (on the AC brackets) of cutting, grinding, checking fitment, cutting and grinding some more, we finally managed to get this radiator mounted up to the AC. Fortunately for us we had the tools and the time to get the job done, but beware that this is not a simple "plug and play" job. There's a reason its a lower cost solution, but thankfully an effective one. Temps seem nice and cool though we did this swap in the dead of winter so its hard to tell how much. Time will tell at the road races in the spring.

    mishimoto radiator

    mishimoto is a very nicely made sturdy radiator, definately an upgrade for cooling, looks & service life... nice fit, went right in, had to trim hoses a bit because it's slightlly closer to the engine because it's thicker. noticed right away the cooling fan was not coming on as much because of increased cooling.

    Mishimoto Radiator 05+

    Since the blower installation has a 160 deg. thermostat, I assumed that the triple core radiator would keep the temp closer to that figure. The original single core radiator must be very efficient since I haven't seen anything like the temp drop that I was expecting. It's a quality piece and I'm not removing it, but it's not as good as I was expecting.

    Helped Cool Heads 30 Degrees

    Running an '06 GT with no power adders but noticed that in 90 heat with stop-and-go, my temp gauge actually started to rise and kill performance. The temp gauge on these cars is only half a fake: Once the heads hit 240 degrees, the gauge will actually move from it's usual 49 to ~75 as a "hey, you're actually starting to get pretty hot" warning, until the heads cool off again. With aluminum heads that's a big no-go. So, replaced t-stat with an OEM 195 degree (a cooler t-stat like a 180 or 160 is NOT a proper fix for an overheating problem), and still no improvement. Water pump had no leaks and the drip hole wasn't showing coolant, belt was tight, so I figured it must be the OEM electric fan/radiator. Replaced radiator with this Mishimoto and picked up the SVT fan. First impressions, the Mishimoto is well-built. Welds are consistent and thick, no warping or rainbowing, all the plumbing connectors and mounting brackets and holes lined up, fan holes and brackets lined up, fit the SVT fan perfectly. Hardest part was getting the OE radiator out of the bay without messing up my condenser's coils and lines (the condenser and radiator are held together at the bottoms with two screws). This thing fit like a glove with the SVT fan (which is actually a tad thinner than the OE fan). Cylinder head temps, so far, are down an amazing 30 degrees. Went from 230 at a long idle to never going above 200 on a hot, near-90-degree day. NEVER let your heads get that hot for that long. You notice your temp gauge rising, try this radiator and a new fan. The OE radiator and fan are too small, they look like they belong on a sedan. Aluminum heads on a hot 3-valve will warp with heat, so this was a great investment for a daily driver.

    Bad fit but good cooling

    Just finished the install of of this radiator on my 2012 GT. My car did not have the performance pack and I added the Ford Racing oil cooler along with this radiator after having overheating issues at a local track. First impressions were good, the packaging is excellent and fit and finish seemed acceptable. However during install I quickly realized the fitment was questionable, with the top A/C condenser brackets NOT EVEN REMOTELY CLOSE to lining up. After an almost 2hr delay while I hammered and filed the A/C condenser, things finally went together. Mishimoto really needs to inspect their JIG or verify fitment on late model S197 Mustangs. Cooling performance: After things finally went together I took her on a quick drive. Too much traffic to really get on it, but while cruising on an 85 degree night my radiator never budged from 194, and would have gone lower if I wasn't using a factory thermostat. Factory radiator would reach 196 or higher on same stretch of road at steady state cruise. Overall 3 stars. 1 star for good packaging and appearance, and 2 stars for performance. I'm subtracting 2 stars for the terrible fitment, 1 star for each AC condenser bracket I had to mangle. Side note: Mishimoto really needs to have install directions available. The directions I found were applicable to 2005-2009 mustangs only and I noticed some discrepancies on my 2012.

    It arrived well packaged , looks really nice , the quality of the welds seem good. Installation was simple done in my garage in 2hours and a half. Only concern I had was the o-ring on the bottom drain plug of the radiator was allowing coolant to drop out so I replaced it with a better one.

    Exceeded Expectations

    From the moment the product got delivered, one look at the packaging resulted in a great first impression. Then, upon removing the item from the box, I was genuinely impressed with the quality of the radiator. Welds looked clean, all mounting points in good shape, polished nicely, etc. I've only put about 25 miles on the car since the installation, so I cannot comment yet on the long-term success of it. But initially, I'd certainly recommend this product.
