PorscheAuxiliary Turbo Charger Recirculating Pump

Another Shark Werks recommend replacement part for any 997 TT engine-out service. Access to this part is only possible once the engine is out and if you're already doing a coolant fix this would be the perfect time for such a replacement. With over a decade of heat cycles and usage we have found the plastic hardens, cracks and fails over time. The internals have also been known to detorirate and hence we replace it with a new factory unit.

Also recommended:

• When servicing the coolant system, we recommend replacing all rubber hoses on vehicles 10+ years old to ensure there are no leaks later. We offer these sets for the 997 Turbo (Manual here / Tiptronic here), 996 GT3, 997 GT3 & RS, and 997.2 GT3 & RS.
• On 997 Turbo / GT2 and 997/997.2 GT3 & RS models, we also reocommend replacing the plastic oil cooler tubes with our stainless steel pipes (Turbo version link, GT3 version link) to ensure there are no failures later due to the weak construction of this original part.
• We also recommend inspecting and possibly replacing the Thermostat, Coolant Expansion Tank, Water Pump, Camshaft Position Sensors, and Spark Plugs while working on the coolant system.
• Check the condition of your engine mounts (we often replace worn ones with semi-solid RSS upgraded ones)
• Replace the worn-out/cracked Auxiliary Recirculation Turbo Pump
• If your Turbo has the P0021 code and Camshaft issue you can perform this fix at the same time
