We stock more than 60 active MerCruiser cooling parts. Oil coolers make up a big share, in listed sizes from 2 x 5 inches up to 3 x 12-1/2 inches. The heat exchangers and shells run from 3-inch-diameter units for the 470 up to 5 x 22-1/2 inch shells, with units listed for the 454, the 7.4 liter and the 7.3L diesel. We also carry power-steering coolers, several combination power-steering/oil-cooler units and a tandem fuel cooler.
Replacing a transmission cooler? Chris's rule is about every 5 years in fresh water and every 2 years in salt, and right away if metal or water has gotten into the transmission, since metal stuck between the tubes can't be flushed out. See our heat exchangers and coolers guide , or call (804) 333-3677, Monday through Friday 9 to 3 Eastern, if you're not sure which part you need.
