Introducing the FIRST and ONLY upgraded anodized aluminum billet thermostat. Upgrade your Porsche engine with our precision CNC-machined billet aluminum thermostat housing assembly. Designed specifically for the EA839 platform, this direct replacement eliminates the common failure point of the factory plastic thermostat housing. Upgrades/Replaces OEM Part: PAB121115G.

The thermostat is replaced during a water pump replacement to prevent future failure. The EA839's water pump is a common failure which causes coolant migration. This results in a compromised vacuum system which leads to overheating and under boost issues (P0299).

Common symptoms of failing thermostat and thermostat housing:

  • Coolant leaks on the front of the engine
  • Low coolant level warnings
  • Engine coolant overheating or temperature fluctuations
  • Engine coolant not reaching operating temperature
  • Visible cracks in plastic housing
  • Coolant smell from engine bay

Features:

  • CNC-machined from solid 6061-T6 billet aluminum
  • Anodized finish for corrosion resistance
  • EA839 3.0T/2.9T fitment
