🔎 Signs You Need a New Water Pump:
✔️ Visible Coolant Leak – Look under the water pump o r radiator.
✔️ Overheating Issues – Engine gets too hot, especially in traffic.
✔️ Squealing o r Grinding Noise – Worn-out bearings.
✔️ Steam from the Radiator – A sign of a coolant circulation problem.
✔️ Loose o r Wobbly Pulley – A failing water pump pulley.

📌 DIY Test: With the engine OFF, try wiggling the water pump pulley. If it moves too much, the bearing is worn out.
