Audi Radiator

The Audi Radiator maintains heat from the engine so that every journey is smooth and confident for driver and passenger. Audi started in 1909 and quickly built a reputation for sporty sedans, responsive SUVs and groundbreaking technology that stretches the limits of everyday driving. From the legendary Quattro all wheel drive that grips snowy roads to Virtual Cockpit screens that transform gauges into graphics, Audi packs innovation into every cab. Electric e-tron models prove the brand can combine silence with speed, while ongoing self driving prototypes are a hint of an exciting future. Loyal fans love how each Audi combines fine looks with good build quality, producing cars that are eager but mature on city streets or meandering highways. Positioned at the heart of that performance, the Radiator performs as a high efficiency heat exchanger, moving coolant through slim aluminum tubes and sweeping fins that throw excess warmth into the airflow racing through the grille. This Radiator design remains light, resists corrosion and maintains constant temperatures during hard acceleration or slow traffic crawls. An inlet tank directs hot fluid in, an outlet tank sends it out cooled, and the constant cycle protects each gasoline, diesel or electric assisted powertrain throughout the lineup. In short, a reliable Radiator allows the full range of Audi to provide power, efficiency and long engine life without compromise.

Stick with genuine OEM Radiator when you need quality that holds up. Audi crafts these parts to hit strict factory specs for every single unit. They also run each part through rigorous checks during production to maintain high quality. You can find exact Audi Radiator you need in our huge stock at AudiPartsGiant.com. You'll love our low, economical prices too. Every OEM part carries a real manufacturer's warranty, so you can buy with confidence. Returns aren't a headache here because our policy is simple. Plus, our speedy delivery gets orders out fast. Shop today and buy with total peace of mind.

Audi Radiator Parts and Q&A

  • Q: How to remove and refit a radiator on Audi A3?
    A:
    To remove the radiator, first switch off the ignition and all electrical consumers. Undo the retaining screws and securing clips from the air filter housing and ducting, then remove it from in front of the battery tray. For engines other than the 1.6 litre SOHC, move the lock/radiator carrier to its Service position; for the 1.6 litre SOHC, only the front bumper needs to be removed. Drain the cooling system, which may involve removing the electric cooling fan temperature sensor from the bottom hose or disconnecting the bottom hose from the radiator. Disconnect the coolant hoses from the radiator by pulling out the clips and easing off the hoses. Disconnect the wiring from the cooling fan connector at the bottom left-hand side of the radiator and remove the fan assembly. On non-turbo models, remove the radiator side shields and undo the radiator securing bolts, then move the top of the radiator slightly to the rear and withdraw it upwards from the lower mounting rubber grommets. For turbo models, release the securing clip and disconnect the hose from the left-hand side of the intercooler, then undo the two retaining screws at each side of the radiator and withdraw it upwards similarly. If the radiator was removed due to suspected blockage, reverse flush it and clean dirt and debris from the radiator fins using an airline or a soft brush, taking care as the fins are sharp. A radiator specialist can perform a 'flow test' to check for internal blockages, and any leaking radiator should be taken to a specialist for permanent repair, avoiding attempts to weld or solder it. Check the radiator mounting rubbers and renew them if necessary. Refitting is the reverse of removal, and upon completion, refill the cooling system with the correct type of antifreeze.
  • Q: How to replace the coolant reservoir and radiator on Audi A4?
    A:
    To carry out the task of replacement of the radiator, first raise the front of the vehicle and hold it firmly on jackstands. Take off the bottom splash cover and empty the cooling system. Secondly, remove engine covers and front bumper and in 2.0L models, position radiator support panel in service position. Detach the upper and lower transaxle cooler lines of the automatic and seal them with a cap. Have the upper and bottom radiator hose clips lifted to detach the hose to the radiator and twist them (where needed) to release the O-ring. Take out the ducts by removing the air duct fasteners of either side of the radiator. Unplug the air conditioning pressure switch and ambient temperature sensor on the driver side of radiator and position the harness aside. Disassemble the mounting fasteners of the power steering cooler and drop the cooler without unscrewing the lines where provided. Removal of air conditioning condenser mounting fasteners and rotate the condenser out of and down the radiator, careful not to kink, stretch or bend the air conditioning lines. Unscrew the two radiator mounting pins, push the pins upwards to unscrew then remove the radiator. Installation of new radiator Before fitting the new radiator, replace any damaged hose clips, radiator hoses, and O-rings. Installation is done in the same manner as it is removed. Installation Refill and bleed the system and then start the engine checking all the leaks. In the case of expansion tank, empty the cooling system by draining it until the coolant drier is removed. Removal: Before removing the tank out of the engine compartment, take out the expansion tank mounting screw, lift the tank and disconnect the coolant level sensor connector. The reservoir should be clean and clear, so wash the reservoir with soapy water, and rinse thoroughly, etc. Installation is done in the same manner as it is removed.
