TIII5YJ is the number on my engine block. I pulled the fan shroud off and the fan housing and checked out everything. lot of leaves and crap in the cooling fins, the oil cooler prurty clogged up. got to chean all that up. Is it easier to clean the oil cooler on or off the engine? Josh H. Creel 1962 Monza Convertible www.overrust.biz
