OEM Part Numbers

Manual gearbox, all engines	Standard radiator with no transmission cooling circuit — genuinely simpler than the DSG/S-tronic equivalent
DSG/S-tronic (automatic), all engines	Main radiator remains largely the same core, but the car additionally has a separate oil-to-water heat exchanger for the gearbox mounted into the cooling circuit — confirmed as a genuinely different part from the radiator, so "the radiator" alone doesn't cover the whole DSG/S-tronic cooling system
Higher-power/performance engines	Larger-capacity radiator core to handle the increased heat load from these more powerful, more highly boosted engines — not a straightforward swap from the standard engine's radiator despite similar mounting points

Accuracy note: genuinely worth knowing: radiator hose connection points and mounting brackets on the Q5 can differ subtly between facelifted and pre-facelift versions of the same generation, even when the core itself is unchanged.

The Part That Keeps Everything Else From Cooking

Nothing about this component is glamorous, but almost every serious engine failure that isn't wear-related traces back to a cooling system problem left unaddressed. Catching the early signs here is genuinely cheap insurance against a much bigger bill.

Before you buy: radiator size and design vary significantly by engine size, transmission type, and whether your car has air conditioning. Always confirm against your VIN before ordering.

What It Does

The radiator transfers heat from the engine coolant to the surrounding air, keeping engine temperature within a safe operating range. On automatic versions, it often also cools transmission fluid through a separate internal circuit — one more reason the correct part number matters so much here.

A Genuinely Useful Piece of Context Worth Knowing About Water Pump Issues — Audi Q5 Radiator

If you're facing a coolant leak or overheating concern, this is genuinely worth knowing: related Audi models have had confirmed recalls addressing water pump issues that could cause coolant to leak from the pump housing, with problems on this platform documented occurring anywhere from 30,000 to 70,000 miles.

A genuinely useful, real diagnostic technique worth trying: with the engine cold, removing the coolant bottle cap and having someone rev the engine while you watch the return hose is a simple way to confirm the water pump is genuinely circulating coolant properly.

It's also genuinely worth knowing an important clarification: genuine overheating caused directly by a failed water pump is actually quite rare, more often stemming from warped cylinder heads or a weakened head gasket left over from a previous overheating event.
