I am about to replace the oil filter housing gasket and like to know if I can add an oil cooler.
has anyone done this? If so, may be you can guide me as to how the coolant hoses are hooked up and if this upgrade can be done without replacing the water pump which I recently changed.
i appreciate your guidance.

M113 has an oil cooler. Two of the three seals you replace for the job you are doing are for oil cooler coolant passages, which is part of oil filter housing.

I assure you that my CLK500 does not have an oil cooler. Hence my question about upgrading.
i think I have figured it out.
The M113/M112 family of engines come with and and without oil coolers. Those, like mine, that does not have an oil cooler, also has a water pump that does not have a port for circulating coolant through the oil cooler.
So, if I decide to upgrade to an oil cooler, I also have to replace the water pump. Since I replaced the water pump this last December, I have decided not to do the upgrade. Instead, I have decided to change oil more frequently specially during the summer when I rip through the Santa Cruz mountains way more frequently than winter time.
