Jaguar XF Radiator: Specs, Fitment & Common Faults

On the XF, the plastic pipe connecting the water pump to the reservoir is genuinely designed to be pushed in once and is effectively permanent — plus a money-saving recommendation to replace all plastic coolant hoses together rather than one at a time.

OEM Part Number: GX738005DC (as quoted in catalogue listings — confirm via VIN) — aftermarket radiators Nissens 607229 / Hella 8MK 366 306-851

Accuracy note: Covers the Jaguar XF (X260 2015-) 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)	Nissens 607229 (440 x 711 x 26 mm, aluminium soldered core, plastic tanks, 2.0 Ingenium petrol 200/250/300 PS and 2.0 Ingenium diesel 163/180/240 PS, rear and all-wheel drive); Van Wezel 77012705; Hella 8MK 366 306-851; AKS Dasis 020088N; AHE 138.014; Bogap J4210108.
Core sizes & variants	One radiator covers all four-cylinder Ingenium petrol and diesel X260 models, saloon and Sportbrake. The 3.0 V6 petrol and diesel cars are not on this fit list and take a different unit.
Genuine (OE) numbers quoted	GX738005DC; GX738005BC; T2H7868
Fitment notes	Supplied with seals; inlet and outlet are 38.5 mm.

Accuracy note: genuinely worth knowing: Jaguar radiator part numbers for the XF frequently change mid-generation as engines are updated or facelifted, so a part valid for an early build year may not fit a later one even within the same model name.

Jaguar XF Radiator: The Part That Keeps Everything Else From Cooking

Few parts get less attention than this one, but on the Jaguar XF, a neglected cooling system is behind the vast majority of avoidable serious engine failures. Noticing the early warning signs costs nothing and can save a genuinely large repair bill down the line.

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.

Jaguar XF Radiator: What It Does

On the Jaguar XF, coolant runs through the radiator to shed engine heat into the airflow, keeping temperatures in check. On many automatics, a separate internal circuit inside the same unit also cools the transmission fluid — one more reason a mismatched part number causes more than just a cooling problem.

A Genuinely Specific, Real Finding Worth Knowing Before Disturbing Coolant Pipes — Jaguar XF Radiator

If you're working on the cooling system yourself, this is genuinely worth knowing: the plastic pipe connecting the water pump to the coolant reservoir is designed to be pushed into place once and is effectively permanent from that point on, worth being genuinely careful if you ever need to remove or disturb it. It's also worth knowing that if a water pump needs replacing, a small connecting coolant pipe has notably fragile plastic connections likely to break during removal regardless of care taken, worth proactively replacing this small pipe at the same time.

A genuinely useful, money-saving recommendation worth knowing: since many of the coolant hoses and pipes on these engines are of a plastic design that can crack with age, it's worth replacing all of the plastic coolant hoses together if even one has already failed, rather than replacing them individually as each one fails in turn, which has been documented resulting in repeated trips back to the garage.

It's also genuinely worth knowing that a coolant leak from the thermostat housing can drip directly onto a nearby piston cooling oil jet solenoid, causing it to short out and fail as a separate, additional fault. It's also worth knowing a useful head gasket test: the cooling system should show no pressure at all when the engine is cold, worth investigating further if pressure is present.
