To measure a radiator, measure the total width outside of tank to outside of tank and the total height, top of tank to bottom of tank. Racing radiators are typically 19in. in height and 3in. thick.

When ordering a new radiator don't forget about radiator caps, coolant additives, electric fan mounts, and overflow tanks.
