Shark Werks Coolant Pipes - Porsche 911 GT2 RS - 997.2 / 911 GT2 - 997 / 911 Turbo - 997

Description

This set of stainless steel coolant pipes replaces the weak factory plastic units that are prone to failures. (We also offer additional replacement coolant/water hose kits to help complete the job here - Additional Coolant Hose Kit)

This item is considered preventative maintenance and should be installed on all 997 Turbo (2007-2009), 997 GT2 (2008) and 997 GT2RS models. This part is not required or compatible with 996 Turbo models (which already have a metal tube).

This is a separate part / not related to the coolant pipe failure people typically weld or pin: a known weakness of the GT1 engine is that the coolant pipes (6-8 per engine) come unstuck from various housings and cause complete catastrophic coolant failures.

This product fixes a lesser known issue involving the plastic coolant elbow pipes that run to the two oil coolers (aka heat exchangers). These pipes are molded plastic and have a very thin wall where the pipe connects to the engine with an O-ring seal. The problem is that over time and mileage, the thin plastic wall will break down at the o-ring slot (its weakest and thinnest point) causing a crack to appear. Eventually the whole engine will need to be removed in order to replace a cheap plastic tube. Both of these issues have been observed on the 997 GT3 and GT3RS as well.

After a customer spent nearly $2500 replacing this small part due to a coolant leak, costing him two track days and several weeks of downtime, we decided that a permanent solution was necessary and made these stainless steel pipes with CNC billet ends. We believe these should be used in place of the OEM part to avoid the aforementioned costs involved in replacing these leaky tubes ever again.

The engine must be removed in order to install these so we recommend performing the "coolant fix" at the same time or replacing these whenever an engine rebuild is in progress.

Price shown is for the complete set of three pieces. O-rings are included and pre-installed. Made in California from stainless steel.

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.
- On 997 Turbo / GT2 models, we also reocommend replacing the plastic oil cooler tubes with our stainless steel pipes 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
