Review on Dewhel JDM Aluminum Coolant Thermostat Plug For GM 2001-2010 Duramax 6 by Robby Fingaw

Revainrating 2 out of 5

interference is coming! - Engine cooling and air conditioning

Good workmanship on a poorly designed part. In my custom application, the hex head pushes the turbocharger inlet hose far enough to create a disturbance in the internal airflow pattern, and this disturbance will eventually puncture the hose. A recessed hex drive would have prevented these problems.

Pros
  • Allows the use of turbochargers without water cooling
Cons
  • I have no particular complaints about it, everything is fine
