An important component in the smooth operation of the cooling system, the thermostat limits the flow of coolant through the engine. This reduces the time the engine takes to warm-up and helps maintain the optimum temperature once that's been reached. Over time though, and through thousands of heat cycles, the plastic in these units weakens. The result is often cracked and leaking housings. Thermostats can also often become stuck in one position, resulting in engine overheating or running cold. This relatively inexpensive item should be on everyone’s list of items to replace every few years, so as to maintain optimum performance. Made by Germany's Wahler.
Be sure you have enough coolant on hand prior to beginning the job.
