Installation

Koyorad is committed to manufacturing radiators with the best in quality; meeting or exceeding OE standards.   Koyorad Cooling Systems, Inc. highly recommends leaving all installations for a professional ASE Certified mechanic.  Koyorad All Aluminum Racing radiators may require slight trimming of the inlet and outlet coolant hoses to accommodate the increased thickness.  Koyorad All Aluminum radiators are application specific for an easy install and will bolt directly to your factory OEM fan shrouds/fans.  Note:  There are a small amount of vehicle specific applications that may require some modification or even fabrication to make fit correctly.  This is sometimes contributed to slight changes in a car maker’s production/parts and especially in conjunction with other aftermarket modifications. Once installed, extreme care must be taken to eliminate all air from the vehicle cooling system.  Koyorad Cooling Systems, Inc. will not accept damaged products due to neglecting to completely remove air in the cooling system.

Recommended Antifreeze Coolant

It is important that the proper coolant is used for your Koyorad OE Aftermarket Replacement Radiator.  We highly recommend the use of coolant grade listed in every vehicles owner’s manual.  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.  Cooling system additives are not necessary.

When a new Koyorad All Aluminum Racing 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.

Shipping Damage and Mis-Shipments

If shipping damage occurs, it is the customer’s responsibility to handle claims through the carrier.   If an incorrect item is received, it is the responsibility of the customer to immediately contact the Koyorad dealer where the item was purchased.
