Description

RallySport Direct carries a large selection of the Mishimoto Performance Aluminum Radiator to not only improve the cooling efficiency of your vehicle but to also make for an excellent upgrade over your factory unit.

Here are the key features:

  • Full aluminum construction provides increased heat and pressure tolerance, improved heat dissipation, increased durability and improved cooling efficiency
  • Manufactured with TIG-welded end tanks for improved strength and extended service
  • 100% brazed aluminum core for maximum reliability
  • Increased coolant capacity directly results in improved cooling efficiency
  • Included 1.3 BAR radiator cap raises the boiling point of engine coolant to provide a safer and more efficient system
  • Designed to original equipment specifications
  • Designed for manual transmission models

Please note: The radiator cap provided with this particular radiator should replace the stock cap that is located n the expansion tank. Your factory issued/stock radiator cap should be the one used on the Mishimoto Radiator. The Mishimoto radiator cap is a two-way valve, and when compared to the stock single valve, there is a difference in construction, and cannot be used on the radiator. If you try to use the provided Mishimoto cap on the radiator, then you risk overheating.

Quality product, but i personally had some issues on install
Wolfzgangvr6 2 months ago
I have a 2002 wrx wagon. At first glance, the radiator looks amazing. The welds and construction are excellent..... until i had to mount my factory fans... the passenger side fan fit flawless, however tha driver side fan required some modification around the lower hose outlet. I had to shave a half moon around the base of the fan shroud, where the lower hose outlet was, because i would have not been able to fit the fan and the hose/hose clamp in that same space. All the install vids showed direct replacement, but that was not the case in this area for me. I am a certified technician, this is my daily driver, so i made the modifications to get me back on the road. The other problem i had was that my coolant system does not have the hose to connect ro the radiator’s reservior outlet. Now mishimoto recognized that this is different for early subaru’s, and they supply a “plug” with an o-ring, but mine leaked after install. I used chrysler’s triple bond silicone, sealed that area, and re threaded it back into the radiators filler neck. Its been three weeks and i have no leaks, cooling system is working as designed, and i am ACTUALLY HAPPY about how this mishimoto rad is working. I also added the clamps supplied by rallysport and a set of samco hoses. Over-all this is really a quality part, looks amazing, and its meet the standards that mishimoto & rallysport has set forth. This is a GOOD review. Im not mad about the little issues; mostly because I am tech, and i understand these are hand built, so i adjusted to make it work. For the DIY guy, rallysport and mishimoto provide an excellet warranty. Do not be afraid to purchase this product. It really is a great upgrade.

This radiator along with a Mishimoto 154 thermostat will keep your engine running cool, but when sitting in traffic it will heat soak fast. I installed this on a '07 STI and it's a daily driver.

Mishimoto radiator

Well obviously the radiator and fan shroud kit work great! But one thing I did notice was how good it makes your engine bay look. Great product, great quality welds. Can’t go wrong with it!

So far so good with modifications

Was not a direct fit. Had to drill holes near one of the lower screw holes due to alignment issue. Was about 1.5 holes off. Luckily there was a bit of metal there and it wasn't too bad but still a pain. Was looking forward to a direct fit. Overall was fast shipping and product was great.

Excellent quality as other comments mentioned. I did have to chop my lower hose about an inch (Used Grimmspeed hoses). Install is really quick and fast, plan to buy the Mishimoto fan kit in near future. I also used my OEM radiator caps.

  • Q: Mishimoto radiator 03 wrx  Bugeyejeremy92 4 months ago

    Answer

    2003 wrx stock radiator has no filler neck. Metal cooling pipe has 1 outlet that feeds into overflow... was the black nipple supplied by mishimoto supposed to go over the filler neck on new radiator as shown? Or am I supposed to get a metal cooling pipe with 2 openings and rum an extra hose to it ? Thank you.


    • A: It appears that you are using the cap correctly. Please feel free to contact us directly if you experience issues.
