Review on Four Seasons 39009 Expansion Valve by Douglas Holla

Revainrating 5 out of 5

04+ Grand Prix Perfect Fit

2004 Pontiac Grand Prix GTP Comp G. I have 300psi on the high side and 50psi on the low side. Tested with a set of distributors rented from Autozone ($160 upfront but you get it all back on your return). Replaced this part and now my AC is dead cold, fits perfectly, gaskets included, take these.

Pros
  • Engine Cooling and Climate Control
Cons
  • Unsure
