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.

Jaguar XF Radiator: OEM Part Number
| Manual gearbox (older models, where fitted) | No dedicated transmission cooler required |
|---|---|
| ZF automatic, standard climate markets | A plate-type transmission fluid cooler is bolted to the main radiator assembly, using engine coolant to cool the transmission fluid — a genuinely distinct bolt-on unit rather than a tank built into the radiator itself, consistent with the same JLR-wide ZF transmission cooling architecture used across Land Rover's range |
| Automatic, hot-climate markets | An additional auxiliary transmission fluid cooler is fitted alongside the standard plate cooler for extra capacity in higher ambient temperatures — not fitted on standard climate-market cars |
| Higher-power/V8 engines (F-Pace SVR and similar) | Larger-capacity radiator and cooling package overall to handle the increased heat load from the more powerful engine |
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.
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.
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.
