This item is considered preventative maintenance and should be installed on all 997 and 997.2 GT3 and GT3RS (2007 to 2011) models.
The GT3 engine is known for being incredibly robust and reliable, however a few major issues exist with concern to its cooling system, and this part is designed to fix one of these problems.
A known weakness is that the coolant pipes (6-8 per engine) come unstuck from various housings and cause complete catastrophic coolant failures.
A lesser known issue involves the plastic coolant elbow pipes that run to the oil cooler (aka heat exchanger). 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 Turbo models as well.
Price shown is for two pieces. One kit per vehicle is required. O-rings are included and pre-installed.
