Mishimoto Aluminum Coolant Expansion Tank
Subaru WRX 2002-2007 / STI 2004-2016
Features & Product Details
RallySport Direct is proud to bring you high-performance automotive cooling components brought to you by Mishimoto.
On this page, you are looking at the Mishimoto Aluminum Coolant Expansion Tank for your 02-07 Subaru WRX or 04-14 STI. This is a 100% aluminum unit that is TIG-welded, and it improves the under-hood aesthetics especially when compared to the OEM unit. Over time and mileage, the OEM coolant expansion tank can fail due to years of temperature variances. The Mishimoto unit is super durable, and it looks great as well. This is a great automotive aftermarket upgrade for your racecar, rally car, overlander or daily driver!

This does not fit with FMIC. Looks good but too bad it doesn’t fit with this combination.

Our Mishimoto Coolant tank failed after two races. The pictures show were poor welding caused a fracture. Mishimoto WOULD NOT WARRANTY the tank as we purchased it two years ago and no longer have the receipt despite the fact that our race team promoted their products on a number of builds.

Even though I only have 67k miles on my car, the radiator expansion tank was starting to deteriorate. I suppose parts are now made with expiration dates. Install was very easy. Definitely recommend this to anyone whose expansion tank is starting to corrode.

Though slightly overpriced, this expansion tank is a good upgrade from the trash Subaru decided to equip vehicles with. It's easy to install. Even people with little mechanical experience can do it.

It crack where there is a small weld of like 2 inch or less.. Compare side by side the Morosso one its welded on the entire bracket.. Mishimoto didnt weld enough and thats what happen with the cold and hot temperature, failure waiting to happen. Its warrantied yes.. but worth the money and time for shipping etc?!!? No for me. Private shop welded it for 10 bucks and was ready to go in an hour. Bracket Fully welded..like it should have been in the beginning.
