Product Details Part Number: AM-31641404

The front seal on the original pipe is prone to failure due to corrosion, resulting in coolant leaks. This was previously a labor intensive and costly repair, not anymore. This water pipe kit was designed to reduce labor time and the cost associated with water pipe replacement on these applications by allowing for installation without removal of the timing cover, saving you thousands!
