About this Radiator

The GENUINE VW/AUDI 1K0-198-251 radiator releases engine heat to the air flowing through it, keeping the engine at its correct operating temperature. Many European radiators use plastic end tanks that can crack with age and heat cycles.

Frequently asked questions

What are the signs of a failing radiator?

Coolant leaks or white or green residue on the radiator, a cracked plastic tank, frequent low-coolant warnings, or the engine running hotter than normal, especially in traffic or when towing.

What should I replace along with the radiator?

Replace the O-rings, clamps and any brittle hoses or plastic fittings at the connections. If the car has high mileage, it is a good time to consider the thermostat and the expansion tank as well.

What coolant should I use?

Use the coolant your car's manufacturer specifies, mixed to the correct ratio, and flush the old coolant if it looks dirty or contaminated.

How do I refill the system after installation?

Fill with the correct coolant and bleed the air out following your car's procedure, which may include bleed screws or an electric water pump bleed routine. Trapped air can cause overheating even with a new radiator.

How do I make sure this radiator fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
