Porsche Engine Water Pump and Thermostat Kit - Geba/Wahler 996WTRPMKT5

This kit from the Porsche team at FCP Euro includes everything you need to refresh the cooling system on your M96 powered Porsche.

In this kit, we've opted to include a Geba water pump featuring a metal impeller, paired with a low temp OE thermostat from Wahler. For the Porsche enthusiast that enjoys a canyon carve, a backroads blast, or a track day, the low temp thermostat is a great choice to keep engine temperatures under control.

Metal water pump impellers solve the issue of composite impeller degradation. However this issue is replaced by the separate concern of damaging your aluminum engine block in the event of a bearing failure. The clearance between the aluminum block and the impeller blades on these motors is very small. If there were to be any misalignment pertaining to installation or bearing failure, metal impeller blades would do significantly more damage to your engine than a composite impeller blade.

M96 engines are plagued by higher temperatures in cylinders 5 and 6 due to a lack of fresh coolant flow to that section of the engine. If not addressed, this often results in localized hot spots, causing excessive wear to the cylinder walls from oil film breakdown. A lower temp thermostat starts circulating coolant through the system earlier, beginning at a lower temperature, leading to a lower propensity to overheat in the first place.

If bore score and cylinder temperatures concern you as an M96 owner, we recommend using Liqui-Moly MoS2 with your choice of our high quality oils to protect that thrust side cylinder wall.

Please note that in 40-50 degree F conditions, the car may take slightly longer to warm up. Please be conscious of engine operating temperature before operating the engine above 4 thousand RPMs.
