VW Golf Passat Tiguan Audi A3 Aluminium Brazed Radiator 3C0819031

Product overview

This aluminium brazed core is listed as a car radiator for Volkswagen Group models, referenced to OE number 3C0 819 031. Heat-exchanger cores can corrode, clog internally or develop leaks over time, which shows up as coolant loss, sweet smells, rising temperature gauges or weak heating. Replacing a tired core restores reliable heat transfer and helps protect the engine from overheating damage, particularly when towing or climbing long hills.

Technical specifications

Installation requirements

Allow the engine to cool fully before opening the cooling system. Drain the coolant, disconnect the hoses and remove the old unit, then transfer any required fittings. Refill with the coolant type specified for your vehicle and bleed the system thoroughly to remove air pockets. If you are unsure, have a workshop complete the job and pressure-test the system before returning the vehicle to regular use.
