"The service was fine I got this item sooner than I expected.The thermostat does allow the car to come up to temp properly. It will come up if I let it sit running long enough. However as soon as I start driving the temp drops below 170. Not acceptable!" posted by: on November 15, 2014 view all 1 reviews
