Review on APDTY 737218 Thermostat Coolant Bypass by Kevin Singh

Revainrating 1 out of 5

Recommend GM OEM parts.

Does not fit properly. Wrong bent (had to be bent again - not easy). Fuel rail not seating in injectors (needs to modify fuel rail bracket) Pushing end @ thermostat too large in diameter (needs grinding to reduce a few thousand, not easy either as it's SS) Mounting bracket clearly misaligned and broken. Recommend GM OEM part.

Pros
  • Meets or exceeds OEM specifications
Cons
  • A later model could have been selected
