Review on Stant 14419 Thermostat Degrees Fahrenheit by Anatoly Yorgason

While replacing the water pump and timing belt on my wife's Golf, I changed the antifreeze and thermostat. Although I didn't use a VW thermostat, this was a tried and tested German device. It was fine for a month or two, then I started getting the "engine not warmed up" check engine light and the heater wasn't as hot as I remembered. I checked everything possible and didn't find anything obvious. So I bought this thermostat hoping the quality would still be there. I changed it and there were no problems at all and now the heater works really well. Thanks Stan for the quality.
