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.

Not to pleased
Scoob 2 years ago
My stock radiator in my 09 wrx cracked, so I purchased this radiator. It's a very nice set up, thicker core than stock, clean wields but my cap would not screw one due to excess aluminum weld build up. I had to cut out the build up to put the cap on. I will attach pictures of the build up and how much I had to cut out.

Perfect OEM replacement
The Lagacy 2 years ago
I bought this the day I moved to TX from CO. Literally the very day I got here. My radiator blew at the seam on my way home from family's house the night I got in to town. Bought this that night and it arrived about 4 days later. Packaging was perfect, blah blah blah. Down to the brass tax, I didn't put this in a WRX, it's in my LGT and it was drop in and perfect, it's been 6 months and I have no problems with it what so ever. I can say that with the dual core, you will have some epic clearance issues between the fans and the front pulley. Extensive trimming of the hose was required, but it does fit. by about 5mm on either side. BUY THIS.

Fits the 05-09 LGT
Travis Reimer 3 years ago
I bought this radiator when my factory piece blew the seam on me. After looking at the LGT specific radiator, which is $360 i wanted to look for something that was cheaper and since i know that the WRX shares a platform I looked no farther. Rallysport told me that they couldn't confirm fitment, which is a little odd, given that I opened the box to find a little card telling me which return fitting to use for a legacy. Just open the box guys! anyways, this thing dropped right in, just barely. Significant trimming of the hoses is required and upper hose clearance leaves a lot to be desired. I've got roughly and 1/8th inch on each side of the hose. Great product though, and LGT owners have a competitively priced option too!

  • Q: Radiator fans  israelruvalcaba27 1 year ago

    Answer

    Would I need to upgrade fans if I get the mishimoto radiator or can I use the OEM fans


    • A: This can be used with the OEM fans.

  • Q: Durability?  Ears2305 4 years ago

    Answer

    I've been thinking about bumping up the cooling efficiencies of my car. My concern is I live in Ohio, so we have hot summers then cold and very unpredictable winters. Will this radiator stand up to the potential salt and low temps, or would this be a fair weather part?


    • A: These radiators tend to be far superior in both performance as well as durability over the OEM unit. Many of our customers use these in hot and cold temperatures without issues including here in Utah. You will always want to make sure there is enough antifreeze in the coolant mixture to prevent freezing but other than that this radiator will hold up just fine.

  • Q: Coolant?  travelguy2k 4 years ago

    Answer

    Do i still need to use the Super Blue coolant, or would a more generic option be just as good/safe?


    • A: You will want to use the coolant specified in your owners manual.

  • Q: A/T?  Nate D. 4 years ago

    Answer

    I'm assuming based on the title of the product that this will not fit the 4EAT transmission, but do you offer any A/T options for this radiator?


    • A: This radiator does not have a transmission cooler built in like the factory automatic transmission cars, but you can purchase the Mishimoto Universal Transmission or Power Steering Fluid Cooler separately in order to use this radiator on AT cars.

  • Q: Thermostat?  3zero3 4 years ago

    Answer

    Do you have to change the thermostat and all the plastic fans and everything will work fine as well?? Will the Grimmspeed Fan shroud with the tool tray fit over this rad.?


    • A: This radiator is compatible with the stock fans and fan shroud. It is not required to change the thermostat, but is recommended while you have the cooling system drained. The Grimmspeed shroud is designed to work with most radiators and should work with this one as well.
