Mercruiser 1985 - 1997 4.3L V6 with V Belts/Serpentine - *Standard Capacity* (Full System) (#5399-6)

This is a standard capacity system design for Mercruiser Chevy based V6 engines 262 CID sterndrive for model years 1985 thru 1997, with V-Belts or Serpentine belt with the low Stbd mounted alternator which ran up until about 1999.

NOTE: Because of adjustability of the MFH-5399 mounting bracket, the hose running past the idler pulley can be brought into contact with the idler pulley if the installer is not paying attention in that area. The MFH-5230 is adjustable in its location and will clear this pulley with no problems. Therefore, although this MFH-5399 kit will fit the serpentine belt engines, care must be taken to ensure that there is a reasonable amount of clearance from the pulley and belts.

Don't be sold strictly on pricing. The Monitor Standard products have several benefits versus other standard after market systems. This system is based on the high capacity, "OEM" products, even manufactured by the same company that produces the OEM systems for Mercruiser, Volvo Penta, Yanmar, Westerbeke, Polaris, and others. This system utilizes a higher number of cooling tubes, more passes on the sea water portion of the cooler, as well as includes "sealed" dividers. This is the same design technology used by Mercruiser and Volvo Penta on their OEM systems.

Will NOT fit engines with high mounted alternators and/or v-drives. Heat exchanger extends from extreme starboard side of a normal exhaust manifold towards port side clearing most high mounted power steering pumps if any (See above illustration). Plastic expansion tank mounts either on front of heat exchanger or if space is limited on vertical surface next to engine. Full system - Block and manifold. Engine block and exhaust manifold on fresh water system. Exhaust elbows remain on raw water system.

Kit includes heat exchanger, heavy duty translucent plastic expansion tank plus all other components necessary to complete conversion. Some components from engine such as hoses are re-used. Heat exchanger painted black. Brackets and other components painted black or zinc plated. All hose clamps are stainless. Shell and tube type. C12200 all copper alloy construction made to the highest industry standards. Heavy duty dual de-mountable clean out end covers. Zinc anode protection.

NOTE: This system extends about 9" forward of the center of the water outlet on the intake manifold and 9.50" above the water outlet gasket surface. That is without the expansion tank mounted to the front of the heat exchanger.
