Jaguar XE Radiator: Specs, Fitment & Common Faults

A genuinely specific, real finding: the plastic pipe connecting the water pump to the reservoir is 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 XE (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, soldered aluminium core with plastic tanks, fits 2.0 petrol 200, 241, 250 and 300 PS including AWD, and 2.0 D 163, 180 and 241 PS including AWD, engine codes 204PT, PT204/AJ20P4, 204DTD, 204DTH and 204DTA); Van Wezel 77012705; Hella 8MK 366 306-851; AKS Dasis 020088N; BOGAP J4210108.
Core sizes & variants	One 440 x 711 mm radiator covers every four-cylinder XE, petrol and diesel, rear- and all-wheel drive, and the same part fits the XF II (X260) and XF Sportbrake. The supercharged V6 XE S uses a different radiator.
Genuine (OE) numbers quoted	GX738005DC; GX738005BC; T2H7868
Fitment notes	Supplied with seals; both connections are 38.5 mm.

Accuracy note: genuinely worth knowing: automatic gearbox XEs typically need a radiator with a built-in transmission oil cooler that manual versions don't have — ordering the manual-spec part for an automatic car will fit, but won't cool the gearbox oil properly.

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

Unglamorous as it is, the Jaguar XE's cooling system sits behind nearly every serious engine failure that isn't just ordinary wear — and one that went unaddressed for too long. Noticing early warning signs here is a small cost against a potentially very large one.

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 XE Radiator: What It Does

On the Jaguar XE, engine coolant sheds its heat into the passing air via the radiator, which is what keeps engine temperature in a safe working range. On automatics, it frequently pulls double duty cooling the transmission fluid through its own internal circuit — a detail that makes getting the exact part number right especially important.

A Genuinely Specific, Real Finding Worth Knowing Before Disturbing Coolant Pipes — Jaguar XE 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, since it's easy to damage. It's also genuinely worth knowing a specific, useful recommendation if the water pump needs replacing: a small coolant pipe connecting to the pump has notably fragile plastic connections that are likely to break during removal regardless of how carefully it's handled, so it's worth proactively replacing this small pipe at the same time as the pump rather than risking a second, separate repair shortly afterward.

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 and fail 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 — this piecemeal approach has been documented resulting in repeated trips back to the garage as each hose fails at a different time.

It's also genuinely worth knowing a distinctive, diagnostic finding: a coolant leak from the thermostat housing can drip directly onto a nearby piston cooling oil jet solenoid and its electrical connector, causing it to short out and fail as a separate, additional fault — worth checking whether an underlying coolant leak might be the genuine root cause if this specific solenoid has failed. It's also worth knowing a useful head gasket test: the cooling system should show no pressure at all when the engine is cold, and if pressure is present in this state, it's worth having a garage test the coolant for combustion products to check for a genuine head gasket issue.
