How Can I Temporarily Fix a Radiator Leak in My BMW 2 Series?

I’ve discovered a small radiator leak in my BMW 2 Series and need a temporary fix before taking it to a mechanic. Are radiator sealants safe to use, and what are the best short-term solutions for stopping a leak without causing further damage?

If you need a temporary fix for a radiator leak before taking your car to a mechanic, consider these options:

✔ Radiator Sealant: Products like Liqui Moly Radiator Stop Leak can temporarily seal small leaks. However, use them cautiously as they might clog the cooling system over time.
✔ Epoxy o r J-B Weld: For cracks in the radiator, a high-temperature epoxy can provide a short-term fix.
✔ Rubber Hose Repair: If a hose is leaking, wrapping it with a heat-resistant rubber patch and hose clamps can stop the leak temporarily.
✔ Teflon Tape for Leaky Joints: If a coolant pipe connection is leaking, wrapping it with Teflon tape can help.

🚨 Warning: These are temporary solutions! A proper mechanic inspection is needed for a permanent fix.
