Hi Rolaine, I'm glad to assist you. To push down on the spring of a thermostat in a 2014 Chevy Impala Limited, you need to access the thermostat housing, remove the old thermostat, and then carefully compress the spring on the new thermostat while placing it into the housing with the spring side facing down; essentially, you are pushing down on the spring by installing the new thermostat correctly in its designated position within the housing (You can also refer to online video-sharing websites (such as YouTube/Dailymotion) for DIY parts install tutorials). If your car appears in the vehicle fitment information below (after selecting the year, make, model, submodel, and engine size), it is a guaranteed fit part.
