Royal Enfield Oil Cooler Radiator Assembly for Interceptor 650 / Continental GT 650 – 575115/E

Royal Enfield 575115/E Oil Cooler (Oil Radiator) Assembly is the factory-spec cooler that helps stabilise engine oil temperature on the 650 Twin platform—critical for consistent performance in traffic, long rides, and hot Indian summers. If your bike shows oil seepage, bent/corroded fins, or overheating/temperature instability symptoms after a minor crash or stone impact, replacing the cooler with a genuine OEM unit reduces leakage risk and fitment headaches.

FAQs 

Q1 (Fitment): How do I confirm this oil cooler fits my bike?
Check your RC/variant: this listing is ✅ confirmed for Interceptor 650 Twin Euro 4 and Continental GT 650 Euro 4. Also match your existing cooler by mounting points, hose orientation, and overall size with a photo.

Q2 (Fitment): Will it fit BS6 / Euro 5 Interceptor 650 or GT 650?
Not marked ✅ here because Euro 5/BS6 fitment wasn’t verified via an official EPC result in this run. If you have BS6/Euro 5, order only after matching existing part number stamp or sharing a clear photo of your current cooler and mounts.

Q3 (Comparison): OEM vs aftermarket oil cooler—what’s the difference?
OEM matches factory core spec, mounting geometry, and sealing surfaces, reducing leak/fitment risk. Aftermarket units vary in fin density, bracket position, and inlet/outlet machining—common causes of returns and repeat seepage.

Q4 (Installation): What should a mechanic take care of during installation?
Avoid bending fins, do not overtighten banjo/union points, and inspect hoses + sealing washers. After installation, warm the bike and check for seepage at unions.

Q5 (Symptoms): What problems does a failing oil cooler cause?
Oil seepage near the cooler/lines, visible damage to fins, overheating in slow traffic, or inconsistent temperature behaviour under load—especially after a crash or stone impact.

Q6 (Return-prevention): What photo should I check before ordering?
Take a clear front photo of the cooler + a close-up of both hose connections and mounting brackets. If your mounts/ports differ, don’t order—message with photos for confirmation.
