Profile: Aaron Radiator Co., Ltd. specializes in manufacturing radiators, heaters, oil coolers, intercoolers, condensers, A/C compressors, and evaporators. Our condenser & radiator goes in front of the main water radiator, and is prone to damage, which means the gas in the air conditioning system escapes, and the A/C system stops working. Our heater matrix is the little radiator inside the car that heats up the interior. Heater matrix is choked up due to build up of deposits or dirt in the cooling system.
