If you rely on your truck for top - notch performance, a plastic water pump impeller won't do the job. The plastic OEM water pump impellers in the 6.4 Powerstroke often crack along the hub, causing overheating and costly repairs. The Sinister Diesel Billet Water Pump is designed for ultimate reliability. It has a CNC - machined billet aluminum impeller that resists cracking and flexing under load. The pump housing, also CNC - machined from billet aluminum, prevents flexing and warping, ensuring a reliable seal and no leaks. It comes with a high - performance bearing assembly and seal, so you can count on it for years. The housing is anodized in Sinister Blue for corrosion resistance. Sinister offers a 2 - Year/Unlimited Mile warranty. Part Number: SD - WP - 6.4. Features include a CNC billet aluminum impeller, CNC billet aluminum pump housing, an upgraded hub bearing, Sinister Blue anodization, and superior strength and reliability compared to the OEM unit. It includes a Sinister Diesel Billet Water Pump and an O - ring.

Using this water pump is easy. First, make sure your truck's engine is cool. Then, remove the old water pump carefully. Install the Sinister Diesel Billet Water Pump in its place, using the included O - ring for a proper seal. Connect all the necessary hoses and parts. When it comes to maintenance, check the water pump regularly for any signs of leaks or damage. Keep the pump clean and free from debris. If you notice any issues, like strange noises or overheating, have it checked right away. Also, remember that Sinister offers a 2 - Year/Unlimited Mile warranty, so if something goes wrong, you're covered.
