On the Auris, a genuinely useful diagnostic pattern: coolant loss specifically at higher speeds points toward a pressure or cap issue.

OEM Part Number: 164000N060 (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 64691 / Valeo 735213

Accuracy note: Covers the Toyota Auris (E180 2013-2018) as listed in the UK aftermarket catalogues. Radiators are sold by engine, gearbox and air-conditioning fitment, and one model usually has two or three different cores — a thicker core for diesels and automatics, a thinner one for small petrols — with different hose positions, so a radiator for the wrong engine will not connect up. The references below are UK aftermarket listings whose fitment lists name this generation, labelled by brand with the core size in mm; genuine numbers are those quoted against the listing. Check your engine code and whether the car has air conditioning against your VIN, and replace the coolant and bleed the system after fitting.

Radiators (aftermarket)	Ava TOA2400 (550 x 378 x 16 mm, aluminium soldered core with plastic tanks, 34 mm inlet and outlet, supplied with O-rings and clips; fits the 1.4 D-4D 90 PS 1ND-TV in hatchback, estate and van); Nissens 64691; NRF 53764; Valeo 735213; Van Wezel 53002400; Mahle CR 1865 000S; Prasco TY090R006
Core sizes & variants	The 1.4 D-4D takes the compact 550 x 378 x 16 mm radiator; the 1.6 and 2.0 D-4D take the much larger 664 x 383 x 26 mm radiator with 38 mm pipes. The 1.33, 1.6 and 1.2 Turbo petrols and the 1.8 Hybrid use other radiators not confirmed here.
Genuine (OE) numbers quoted	164000N060 (1.4 D-4D); none quoted for the 1.6/2.0 D-4D radiator
Fitment notes	The Ava radiator comes with O-rings and clips; petrol and hybrid Auris owners should order against the VIN.

Accuracy note: genuinely worth knowing: some Auris engines pair the radiator with an integrated oil cooler or a separate charge-air cooler depending on turbocharging — these aren't interchangeable, so confirm your exact engine spec before ordering.

A Genuinely Useful Diagnostic Pattern Worth Knowing About — Toyota Auris Radiator

If you're losing coolant specifically through the overflow or header tank pipe, and it seems to happen only at higher speeds, this is genuinely worth understanding: this specific pattern points toward excessive pressure building up in the cooling system, rather than a head gasket issue, particularly if a proper block test has already ruled the head gasket out. A radiator cap that's no longer holding pressure correctly, or a partial blockage somewhere in the system, are both worth checking.

A genuinely useful technical explanation worth knowing about water pump noise: a whining or grinding noise from the water pump area is typically caused by bearing wear, and in more advanced cases, the impeller itself striking the housing once the bearing has failed enough to let it shift position.

It's also worth knowing that coolant leaking specifically from the water pump's shaft seal, visible as a small weep beneath the pump, is often one of the earliest signs of pump failure.

Toyota Auris Radiator: The Part That Keeps Everything Else From Cooking

It's an unglamorous part, but on the Toyota Auris, the cooling system is behind almost every serious non-wear engine failure that could have been prevented. Spotting trouble here early is about as cheap an insurance policy as exists against a genuinely expensive repair 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.

Toyota Auris Radiator: What It Does

On the Toyota Auris, heat from the engine coolant is shed to the surrounding air through the radiator, keeping engine temperature in a safe range. On automatic gearboxes, it often doubles up, cooling transmission fluid through a separate internal circuit too — which is why getting the exact part number right matters more here than on a simple heat exchanger.
