Mercedes Benz C230 Water Pump
Know What's Up with the Mercedes Benz C230 Water Pump
If your car starts to overheat, then you'd better check up on the Mercedes Benz C230 water pump. Otherwise, it can pose even more serious issues and entail you to replace the part; it's quite expensive if you buy a new one. So, it would be a great idea if you troubleshoot the problem and pay for much more affordable repair fees. Here are some tips to help you diagnose a bad water pump.
Loose cooling fan
Locate the cooling fan on your engine and shake it up and down. If you see that the bearings are used, then you'll definitely have to replace the water pump. A loose bearing is also one of the factors why the engine creates unusual and incessant noises.
If there's a leak in the water pump, then it's a sure problem. Place a mirror under the water pump to inspect if there is a hole that's causing the leak. It's normal if you notice a few drops; but, if you discover that there's a great loss, then that's an issue. If you find out that the weep hole is soaked with coolant, then you'll surely have to get a new Mercedes Benz C230 water pump.
Another reason why the water pump leaks is because of a worn gasket. Inspect the water pump if you see any damaged ones. If the pressure also significantly drops, then the leak could be worse. This can be caused by a shabby gasket and you'll have to replace it with a new one.
Low coolant level
While the engine is off, open the compartment and inspect the level of the overflow reservoir and the engine coolant. These should indicate that they're full. If not, it means that you have to fill it up again. Remember to let the engine cool down before opening the radiator.
Wiggling water pump pulley
Grab the water pump pulley and shake it. If it moves, then it means that the bearing is broken and you'll need to have the water pump replaced. You also have to see to it that the belt is on the water pump pulley to avoid any issues.
