There is no alternative to the OEM thermostat for this type of engine (3FE). What we find works is simply a cooling system that is in good shape, i.e. if you are rebuilding the engine, and the water pump, thermostat, and radiator are fairly well aged, it would be a good idea to replace them. The same would be true for the hoses in the cooling system. Engine oil coolers are an excellent idea regardless of the type of engine you are running. We recommend a matching oil cooler thermostat.
