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.

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.

The Part That Keeps Everything Else From Cooking

Nothing about this component is glamorous, but almost every serious engine failure that isn't wear-related traces back to a cooling system problem left unaddressed. Catching the early signs here is genuinely cheap insurance against a much bigger 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.

What It Does

The radiator transfers heat from the engine coolant to the surrounding air, keeping engine temperature within a safe operating range. On automatic versions, it often also cools transmission fluid through a separate internal circuit — one more reason the correct part number matters so much here.

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.
