Toyota Verso Radiator: Specs, Fitment & Common Faults

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

OEM Part Number: 164000R030 (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 64693 / Valeo 735188

Accuracy note: Covers the Toyota Verso (2009-2018) 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)	Denso DRM50072 (665 x 376 x 27 mm, fits Verso 1.6 D-4D 1WW, 2.0 D-4D 1AD-FTV 124 and 126 PS, 2.2 D-4D and D-CAT 2AD-FHV, shared with Auris and Avensis T27 diesels); Nissens 64693 (664 x 383 x 26 mm, aluminium core, plastic tanks, 38 mm connections); Valeo 735188; NRF 53181; Mahle CR 28 000P; Van Wezel 53002402; Hella 8MK 366 308-751; Ridex 470R0980

Fitment notes	for petrol Versos quote the VIN or check for the 16400-0T or 16400-37 number on the old radiator before ordering.

Accuracy note: genuinely worth knowing: Toyota sometimes fits a heavier-duty radiator as standard on Verso trims with towing packs or higher-accessory-load options — worth confirming your exact spec rather than assuming the base-model rating applies.

A Genuinely Useful Diagnostic Pattern Worth Knowing About — Toyota Verso 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 Verso Radiator: The Part That Keeps Everything Else From Cooking

This isn't a part anyone gets excited about, but on the Toyota Verso, overlooked cooling problems are responsible for most serious engine failures that aren't simple wear-and-tear. Catching the early symptoms is about the cheapest insurance available against a major bill later.

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 Verso Radiator: What It Does

Keeping the Toyota Verso's engine temperature within safe limits comes down to the radiator's job of transferring heat from the coolant into the surrounding air. Automatic-gearbox versions often build in a second circuit for transmission fluid cooling too, which is exactly why fitting the wrong part number can cause two problems, not one.
