Water Pump May Develop Coolant Leak

The low coolant light may illuminate and/or the engine may overheat as a result of a coolant leak from the water pump. The leaking pump will require replacement and the entire cooling system should be inspected for leaks as it is not uncommon to find multiple leaks on higher mileage vehicles.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

Check Engine Light and/or Engine Overheating

The thermostat may fail resulting in engine overheating and/or illumination of the Check Engine Light. Replacement of the thermostat along with a complete inspection of the cooling system will be necessary to correct this concern.

Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

2006 BMW Z4 Reviews

Freeway driving rough and too sensitive with run flat tires. Replace will ride and handling much better. I had manual transmission and have to run RPM to above 4000 to get shifting to feel right. Exhaust did not sound as it should be. When set to Vent. Warm breeze came out. Steering a little too sensitive.
