If you have noticed a buildup of grease around your wheel well, the most likely cause is because your cv boot has torn, and is throwing the needed grease around your wheels and engine bay. When the boot is torn, it allows dirt and debris to contaminate the cv joint, which can cause damage and a costly repair.

The radiator tank cap keeps necessary pressure on your coolant to increase efficiency. If you have an overheating issue in your vehicle, a simple, quick, and inexpensive part to replace is this cap. Often times, the coolant is not kept under enough pressure to keep it from boiling or expanding too much. This cap keeps all the heat and liquid inside the coolant system for maximum efficiency. Should be replaced each time major coolant system service is performed.
