Product Details

The Sierra 18-70934 is a precision-molded coolant hose designed for MerCruiser stern drive marine engines. This OEM-quality replacement hose connects the circulating water pump to the thermostat housing on large-block GM V-8 engines, ensuring proper coolant flow and engine temperature regulation.

Key Features:

  • Pre-formed white rubber construction for exact OEM fit
  • 1-3/4 inch inside diameter x 14 inches length
  • Engineered specifically for 454 cubic inch (7.4L) MerCruiser engines
  • Also fits MCM/MIE 427 and 502 CID V-8 applications
  • Durable molded design eliminates the need for complex bending
  • Resistant to marine environment conditions

This hose directly replaces MerCruiser OEM part numbers 32-897181, 32-89718, 32-16010, and 32-46828, as well as Mallory 9-44051. Sierra Marine manufactures this hose to factory specifications using quality materials for reliable performance and longevity in demanding marine applications.

very easy and fast purchase but concerned as fedex requires no signature for delivery and is not careful to which house yard it leaves packages in the front of ,so far anyway.

Doesn't list if it fits my vehicle.

Placing an order went very smoothly. Thanks.

I found what I wanted easily and the process was quick and easy.

Good company to deal with, will gladly do business here again.

So far so good. Best price I found for his item.

Autoplicity is my number one choice for auto parts.

I'm not sure about this order, I hope it fits.

Great price, great business and quick shipping. Excellent transaction and would recommend them again.

I saved a lot on the PIAA 520 ATP lights I purchased for my FJ Cruiser and I can say that because I looked everywhere. A couple hours after placing my order I decided t call and ask to pay for expedited shipping. I had the BEST customer service experience! As I build my FJ, I will buy everything I can HERE.
