Mercruiser 470 Cooling System Diagram Re: filling the cooling system 470. i flushed and replaced the antifreeze in my 470 recently when i installed a 4" heat exchanger. i filled mine to the top of the neck and then started the engine.the level fell a bit and i added more while the engine was running. i replaced the cap and watched my temp gauge carefully run up to 160* and level out. Iously designated as 470, 485 and 488. the 1985 470 and 488 models were redesigned as 170mr and respectively to indicate. the use of the new style gear housing. all models of this engine are essentially the same, differing primarily in camshaft. rofile and valve train specifications.the cylinders a. e numbered l 2 3 4 from front t.
A Visual Guide To The Mercruiser 470 Cooling System The cooling system is another crucial part shown in the mercruiser 470 parts diagram. this system prevents the engine from overheating by circulating coolant throughout the engine block. the diagram highlights the location of the water pump, thermostat, and hoses, allowing users to identify and inspect these components for any potential leaks.

They are specific to the 3.7 (aka470 485 et.all). the rods, pistons and head are based on ford parts. the front of the head has a large hole machined in it for a water circulation. the rods are ford rods but the 429 460 bearings will not work with the merc crank .tangs radii issues if i remember correctly. Note: refer to section 6d ‑ water flow diagrams for full loop and half loop cooling system flow diagrams. sterndrive models with closed cooling alpha models with closed cooling alpha sterndrive models with closed cooling are equipped with a seawater pump on the engine. however, a through‑the‑hull or.
