A new radiator manufacturing process is currently being phased into production to provide longer radiator life. Part of the process change is to cut, lance or pierce the two (2) supports that connect the inlet and outlet tanks to relieve thermal stresses in the radiator. These cuts are located at the top and bottom of the radiator in the "U" shaped support. Refer to Figure 1.
Do not replace or return radiators because they appear to have the saw cuts in them. Those cuts are a design requirement. All cars and trucks will have saw cut radiators at some point during the 1994 and 1995 model years.
