Review on Denso Radiator: Optimal Heat Dissipation for Efficient Engine Cooling by Josh Koa

This radiator is a great OEM replacement. It comes fully assembled (transmission fittings already installed) and includes a radiator cap. The build quality appears to be high. Everything was easy to connect and fit the first time. I didn't have to change anything. You will probably want to replace most if not all of the screws that are 6x16 metric except for the one holding the driver's side fan which will likely be 6x12 or even 6x10 with a washer on it. . 6x16 is too long for this spot and presses on the plastic underneath. If you don't know what you're doing, the best video I've found on the internet is Eric Race Car Driver driving a 1999 Acura 2.3 CL (it says "How to Replace a 1999 Acura 2.3 CL/Accord Radiator"). on Youtube. It's very similar to Accord but with a few differences. This radiator job is very similar to the 4-cylinder Accord (4-door EX, KA 4AT) of that era (98-02) but there is no relay at the top and instead the wires at the top of the fans are cut in the three places you to need. to loosen (clamps will likely break, but zip ties will do). You'll also be relieved to know that the fan (on the right as it's in front of you) is only bolted on at the top, leaving you with two rusty nuggets to contend with, just one on the air conditioning and two on the transmission if you've got an automatic. It's probably worth checking out the '99 Civic radiator video he made for more helpful tips on removing broken bolts from the underside of the radiator. I often use metal snips to cut through the plastic on an old radiator where the broken screws are underneath. There is no point in connecting one of your transmission cooling hoses to the radiator. If you live in a salt belt like me, you will most likely find that it is rusted as hell and possibly covered in gear oil in the process of rusting. You might want to have a piece on hand when doing this job. This is Honda part number 25210-PAA-020. And yes, removing the hoses from the hard lines above is the absolute only way out. One last tip, you can also replace the power steering cooling tube, part number 53765-S84-A01, another metal tube that runs behind the radiator and cannot be done without removing the radiator or possibly the fender. Mine got rusty last summer and lost power steering fluid.
