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 covered with the top brands like Mishimoto, Koyorad, Skunk2, Moroso, and more!

Radiator caps are designed to keep coolant from leaking out of your radiator. It is important to make sure your radiator cap is in good condition so that it can withstand coolant pressure under hot temperatures. If your vehicle is leaking coolant from its radiator cap, replace it as soon as possible.

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.

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 vehicle's 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 vehicle's 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 engine's cooling system.
