2019 Discovery Sport 2.0T — Coolant Leak Diagnosed & Repaired at Home

The owner contacted us having noticed the coolant level was dropping and spotted a visible leak underneath the vehicle. Our advice was straightforward: don't drive it. A coolant leak on a running engine is not something to push your luck with — the risk of overheating and serious engine damage isn't worth it. We arranged to attend within the following days.

Finding the Fault — Without Unnecessary Disassembly

Before removing anything, we used our bore scope to identify the source of the leak. This is exactly the kind of tool that saves time and avoids unnecessary work — rather than stripping the front end on assumption, we were able to pinpoint the fault clearly first. The thermostat housing was identified as the source of the coolant loss, a known failure point on the Ingenium 2.0-litre engine fitted to this generation of Discovery Sport.

Sourcing the Right Part

Once the fault was confirmed, we sourced a genuine Land Rover thermostat housing — making sure we obtained the latest revision of the part. Land Rover had updated the component, and fitting an older revision when a current one is available makes no sense. Genuine parts, correct specification, latest revision. That's the standard we work to.

The Repair

Accessing the thermostat housing on this vehicle required careful removal of the front bumper and radiator assembly — it's not a quick or straightforward job, but it was carried out methodically at the client's home address.

Carried Out at the Client's Home

This entire repair — front bumper removal, radiator out, thermostat housing replacement, cooling system bleed and pressure test, air con degas and regas coordinated through a trusted local specialist, road test and diagnostic scan — was completed at the client's home address. No recovery truck needed, no courtesy car, no sitting in a waiting room. The vehicle was repaired where it stood, to a standard we were fully confident in before handing it back.

The Takeaway

If you notice coolant loss or a leak under your vehicle, stop driving and get it looked at — the sooner the better. What looks like a minor leak can escalate quickly once an engine gets up to temperature. We cover Cheltenham, Gloucester, and across Gloucestershire, and for Land Rover owners especially, we have the diagnostic tools, the experience, and access to genuine parts to get it right first time.
