Install and secure the shroud next. While I had help removing the shroud, my helper had to leave so reinstalling it was a solo act. To make life easier, I removed the water pump so I didn't have to wrestle with the shroud too much-a precaution on my part to safeguard the fins of the new radiator from shroud damage. Here's what it looked like with the shroud reinstalled and brackets secured. Reinstall the side radiator mounting bracket bolts, hoses, and the fan and fill the new radiator to complete the project. One final tip: Be sure the petcock on the new radiator is fully closed (petcock distended) before you start to fill the radiator. To prevent petcock breakage during shipment, these are usually in the fully-opened (flush with the bottom of the radiator) position.
