| BMW 740i 740iL - Water Pumps & Hoses - Page 1 |
| Is your car starting to run a little hot? Is it overheating while sitting at idle? It's possible you may need to replace your water pump. An easy way to check your water pump is to look underneath the car and check for water seepage out of the pump. This means that water is leaking past the bearing and seals, indicating the pump is on its way out. Another way to check is to squeeze and hold the upper radiator hose for a few seconds (CAUTION: the hose may be hot - use gloves) while the car is running. If you feel no pressure building up, it is a sign that water is not circulating and the pump may be bad. |
