  • Perfect for my 2007 Subaru Impreza 2.5i
No dramas and solid stable temps after 500 miles. I spent 40 minutes burping the system to ensure I could fully test the thermo after a full flush. 5000 feet elevation, full camping car load, pumping ac, 90 degree temps, never moved above a half.

  • Appeared Identical To The Original Subaru
I believe this is the most solidly-built thermostat I've ever handled. Fit perfectly in the water pump of my 2009 Legacy. Opened during the air elimination process. Highly recommended.

  • Product looks OK but packaging was trashed
Product looks OK but packaging was trashed. They put a thinly boxed item in a envelope and it arrived as you would expect, trashed. I hope it works out.

  • Very well made
Was really impressed. Built like a light tank. It dwarfs the other thermostat in size and substance (Heaver spring and much greater overall depth) This was fitted to a 99 Subaru legacy outback. The integral gasket fitted to the recessed lip, fit like it was machined on a lathe.

  • Perfect fit for my 2012 Subaru Impreza
Perfect fit for my 2011 Subaru Impreza 2.5i Premium. Worked well. Have about 1000 miles on it so far and no issues.

  • Great buy
Works great for my 2001 Subaru Legacy outback with the 2.5 sohc

  • OE quality is the only way to go.
OE quality thermostat is the only way to go on such an important part of your engine. Much better heat motors than the majority of aftermarket options which have tiny heat motors in comparison.

  • Fixed my Subaru
Worked as described. Easy to install.
