Product Details

The Moroso 63471 Water Neck Block Off Plate is designed to seal off unused water neck openings on engine blocks during custom cooling system builds or when relocating coolant passages. This precision-engineered aluminum plate provides a clean, professional solution for blocking off water neck ports that are no longer needed.

Key Features:

  • Constructed from lightweight, corrosion-resistant aluminum
  • Features 2 mounting holes for secure installation
  • 1/4-inch mounting hole size for standard fasteners
  • Ideal for custom cooling system applications and engine swaps
  • Prevents coolant leaks from unused water neck ports
  • Professional-grade Moroso quality and fitment

This block off plate is commonly used in racing applications, engine conversions, and custom builds where the stock water neck configuration needs to be modified or eliminated. The durable aluminum construction ensures reliable sealing and long-lasting performance in demanding engine environments.

Easy ordering process

So far so good. Disappointment in shipping...

I got the right parts on time

So far so good.....I can't believe the price on the tires I just ordered; almost too good to be true......

Great service, great product. Received on time and part was well package and met my needs and requirements

Best price online for this muffler

It was great

All seems great. Had item in stock as on there website and it was shipped quickly.

I received my Borgeson steering shaft today for my 1990 dodge 1st gen. This is where I found the lowest price for the product. I was also very pleased in the speedy delivery. I will definitely use this company again.

Autoplicity was quick, and fast! the shipping was standard but arrived in five days! I would definetly recommend them!

Great website, with definitely the lowest prices online. Their system kept me informed every step of the way on my order status. More than the average online store. Autoplicity is now my first stop for auto parts and accessories.

Best price I found on Weathertech digifit floor mats for my 2012 F150 Supercrew. Product was as described and shipping was fast too.

Great prices, helpful customer service. Ordered 2 by mistake. And they got it cleared up real fast. Saved over $80 off retail. Will be ordering from the, again!!!!! <br>
