Review on Denso 221-3209 Radiator: High-Performance Cooling Solution for Optimal Engine Efficiency by John Cox

Great OE replacement for my 2001 Honda CR-V. It's been 6 months since I installed it to replace the original heatsink which was cracked and it still works great! Fits perfectly. Just like the original. Tip: Be sure to buy a new radiator cap, otherwise there may be a small leak. Radiators get very hot and the cap gasket takes the shape of the rim of the radiator filler neck. So if you use an old cap on a new radiator, you may end up with small gaps between the old cap's gasket and the edge of the new radiator's filler neck. A small price to pay for preventing leaks.
