RADIATOR & FAN GP 2005021 - Caterpillar

All 3200 Series Turbocharged Engines
The mounting holes in the cylinder head at location (A), used for a lifting eye bracket (or for other brackets), may be a different size than the original head; therefore rework and extra parts may be needed. Cylinder heads on earlier engines had bracket mounting holes with 3/8-16-2B threads. Later cylinder heads had bracket mounting holes with 1/2-13-2B threads.(1) If a cylinder head of the earlier type is replacing a later cylinder head, the replacement cylinder head will have 3/8"-16-2B threads in the mounting holes. Install the bracket with S1594 Bolts and 5M2894 Washers.(2) If a cylinder head of the later type is replacing an earlier cylinder head, the holes in the lifting eye bracket, and other brackets, must be enlarged to 13.0 mm Ø (0.53" Ø). Use 6H1717 Bolts and 5P8245 Washers to install the bracket on the replacement cylinder head.3208 Turbocharged Engines
(1) If the cylinder head is to be used on the left side of the engine, install a 9L7657 Cup Plug at location (A). If the cylinder head is to be used on the right side of the engine, install a 9L7657 Cup Plug at location (B). On all cylinder heads, install a 7H3181 Hex Countersunk Head Plug at location (C). Install 5M6213 Plugs at locations (D) as necessary. Due to the different size holes in earlier and later cylinder heads, install either a 2B858 or a 5M6214 Plug in the opening at (E).(2) Put the cylinder head in position on the engine. Put engine oil on the threads of the cylinder head bolts and install the bolts in their correct positions. Tighten the bolts in sequence and to the torque shown in the Service Manual.3204 Turbocharged Engines
Because two different water lines groups have been used on these engines, it may be necessary to obtain some additional parts. See Step 1 and the illustrations for the parts needed. (1) Install a 7H3171 Hex Countersunk Head Plug at location (A), a 9L7657 Cup Plug at location (B), and 5M6213 Plugs at locations (C) as necessary.(2) New vent line parts (not part of the cylinder head group) will be needed if the threaded hole at location (D) is a different size than the hole in the former cylinder head. See the illustrations for the parts needed to make a new vent line.(3) Put the cylinder head in position on the engine. Put engine oil on the threads of the cylinder head bolts, and install the bolts in their correct position. Tighten the bolts in sequence and to the torque shown in the Service Manual. Connect the vent lines as shown. Cylinder heads for 3204 Turbocharged Engines were originally built with a single valve spring per valve. This replacement cylinder head contains two valve springs per valve (double valve springs). However, this cylinder head group (with double valve springs) is directly adaptable for use on 3204 Turbocharged Engines. No changes or modifications are required. For replacement valve spring parts for this cylinder head group,
