F Pace Radiator Fan Failure Causes Engine Overheating

Had the same issue on a 2020 Jaguar XF with the 2.0L engine. The electric fan not engaging caused severe overheating in traffic. Initially thought it was the fan motor, but diagnostic testing revealed a faulty connection at the fan control module. The root cause was corrosion in the wiring harness connector that controls the engine cooling fan. When these connections get compromised, the fan fails to activate at the proper temperature threshold. This can quickly lead to dangerous engine temperatures, especially during idle or low-speed driving. The fix required replacing the damaged wiring connector and fan control module. This was not a simple plug-and-play repair, the entire front bumper had to come off to access the components properly. The fan clutch and related cooling system components were thoroughly tested after repair. Would strongly recommend getting this checked soon. Running with a non-functioning cooling fan can cause major engine damage. These symptoms match exactly what I experienced before the repair, and delaying service only risks more extensive problems. Once fixed, the electric fan should kick in automatically around 90-95 degrees engine temperature. You can verify proper operation by listening for the fan when stopped at idle with the A/C running.

Thanks for sharing your experience with the faulty fan control module. Vehicle overheating is definitely not something to ignore. I had a very similar temperature control issue with my F Pace last summer. The electric fan would out of nowhere stop working, causing the engine to overheat in city traffic. After diagnosis, they found the temperature sensor was sending incorrect signals to the fan control unit. This meant the electric fan wasnt engaging when needed. Been working perfectly since the repair with proper cooling system function. Do you remember roughly what you paid for the fix? Also curious if youve had any other cooling-related problems since getting it repaired? The fan clutch assembly can sometimes cause recurring issues even after initial repairs.

Good news, got the electric fan issue fully resolved for just 95€. The mechanic found and fixed a damaged plug connection that was preventing proper fan motor operation. Since the repair, the temperature control system has worked flawlessly with no overheating issues. The radiator fan now kicks in exactly when it should, especially in slow traffic. No more temperature gauge climbing into the danger zone. Much cheaper fix than I initially feared, since it didnt require replacing the entire fan assembly. To answer your question about recurring problems, absolutely none in the 8 months since the repair. The cooling system maintains proper temperature consistently now. Regular maintenance checks show all components working as designed. Really glad I got it fixed when I did. Having a properly functioning electric fan is crucial for preventing engine damage from overheating. If you're still experiencing issues, definitely get it checked soon to avoid more serious problems.

Thanks for the advice. Just wanted to share how my repair went since others might find it helpful. Finally took it to a specialist mechanic last week when the overheating got worse. Turns out the electric fan control module had water damage, likely from a small leak that went unnoticed. The mechanic found corroded connections and replaced both the module and wiring harness. Total bill came to 280€ for parts and labor. The engine cooling system is working perfectly now. Fan kicks in right when needed and temperature stays steady even in stop-and-go traffic. No more watching the temp gauge climb while sitting at lights. Really glad I didnt wait longer to get it fixed. The mechanic said a few more weeks of overheating could have caused serious engine damage. For anyone else seeing similar symptoms, definitely worth getting checked out sooner rather than later.
