Cooling products are essential components to keeping your vehicle running at optimal temperatures. Whether you are looking for a radiator, fans, or oil coolers, we’ve got you coered with the top brands like Mishimoto, Koyorad, Skunk2, Moroso, and more!
Radiators cool down and store the coolant in your vehicle. Aftermarket radiators typically provide better cooling than factory, and can really clean up the look of your engine bay. Without proper cooling, your engine can overheat. We recommend upgrading your OEM radiator to and aftermarket radiator if you plan on doing any hard driving for long periods of time, or plan to take your car onto the track for heavy use.

About Koyo
Koyo is committed to manufacturing radiators with the best in quality and meeting or exceeding OE standards. Koyo radiators do not require any drilling, cutting, or relocating, yet we highly recommend leaving this installation up to a professional mechanic. If you need help locating one in your area, one of Koyo’s extensive list of distributors will be happy to refer one to you. Feel free to contact us if you have any questions.
Recommended Antifreeze Coolant
High quality antifreeze and coolant protects your engine by lowering water’s freezing point and raising water’s boiling point. Antifreeze and coolant provides anti-corrosion properties for the metals in your radiator and cooling passages within your vehicles engine. It also provides proper lubrication for the engine water pump.
It is important that the proper coolant is used for your Koyo OE Aftermarket Replacement Radiator. We highly recommend the use of coolant grade listed in every vehicles owner’s manual.
When a new Koyo OE Aftermarket Replacement radiator is installed, we require a complete cooling system flush and fill with new coolant mixed 50/50 with distilled, de-ionized or de-mineralized water. Neglecting a full cooling system flush or using the wrong coolant may result in corrosion, leaks, and premature wear and tear, not to mention other stresses on your engines cooling system.
