The engine block is the same and has the mount on the side for the oil thermostat. On cars that do not have an oil cooler they made the alternator bracket larger to include a blanking plate to cover the holes. Both use the same gasket so are prone to the same leaking. The problem is that one of the bolts for the alternator bracket is underneath the engine mount so you have to take the weight off the mount and remove it to ultimately remove the alternator bracket and replace the gasket.
