Product Description

 Kenworth T600 – T800 RDS FLX000315(4) Radiator – 4 Row. 

This radiator replaces OEM part numbers*:

1A020256, X-5101-02, And X-5601-10

*The use of the original manufacturers’ part number or name is for reference and identification purpose only. These radiators are not OEM parts, but are of aftermarket manufacture.

Please use this valuable information when replacing your radiator: When refilling the cooling system, use a 50/50 mixture of fresh antifreeze and clean water (distilled water is best). Getting all the air out of the system is a must, so make use of any air bleeds that are provided. If there are no air bleeds, you may have to loosen and "burp" a heater hose to get all the air out. Some thermostats have a jiggle pin or small bleeder hole that vents air making filling easier. Others do not, and can trap air causing the engine to overheat.

Check the operation of the cooling fan – especially if the engine overheated. On older rear-wheel drive vehicles with a fan clutch, check for clutch slippage or fluid leakage. Fan clutches lose their grip as they age, and can be a common cause of overheating.

Also, don’t overlook the coolant reservoir. The reservoir serves as a storage tank for excess coolant and works with the pressure cap to keep the system full of coolant. If the reservoir is damaged or full of sediment, replace it. Small leaks in the reservoir can be repaired with silicone glue. Also, make sure the hose between the radiator cap and reservoir is in good condition, properly routed, free from kinks or obstructions
