I decided to upgrade to a Mishimoto radiator to replace my slightly-leaking OEM radiator. Here are a few things I wish I knew before getting started.

The Mishimoto is a larger unit and you might worry about the fitment. No issues, although things get tight. You will have just enough coolant to do a 50/50 mix if you buy only one jug.

Things to remove which make this easier: Engine cover, the plastic intake to the air filter box, and the rubber air intake hose between the engine and air filter box. Also take off the coolant reservoir and put it aside.

When unplugging the electric fans remember there are connectors on each side of the fans, total of two. I would remove the upper radiator hose completely and the engine end of the lower hose. When you have the old radiator out, note the position of the lower hose and fit it to the Mishimoto radiator. It's easier to tighten it now than wait until it's in the car.

There were some tips about lubricating the hoses to make them fit the Mishimoto. I had no such issues, however I have aftermarket hoses installed when the timing belt/water pump was done 6 months ago. The top hose probably will need to be trimmed 1-2 inches. You will notice it will dip down into the electric fan housing on the passenger side if you don't trim. Spin the fan to test clearance. The two small hoses which run from the tank on top of the turbo will also need a little trim, just to keep them neat in the bracket.

I was very happy to find nothing to unbolt below the radiator, thus keeping the splash pan in place. Removal of the old radiator is nothing more than some bolt and hose removal. It lifts right out. Get some "mechanics gloves" if you can. A lot of sharp edges and abrasions in this work.
