2004 Chevrolet Chevy Suburban Information on Gradual Coolant Loss Over Time with No Evidence of Leak Found

download
Some vehicles may experience a gradual coolant loss over time. A very low percentage of cylinder head(s) manufactured with an embossed Castech logo may develop a porosity crack in a very specific area. Inspect the cylinder head assembly to determine if the casting was manufactured by Castech. This can be accomplished by inspecting for their casting logo located on top of the intake port, under the rocker arm support rail and in the spring deck cavity portion of the cylinder head. Important: If the cylinder head(s) are Not a Castech casting, follow normal diagnostic procedures in SI to determine the cause of the coolant loss. Refer to the following illustrations on how to identify Castech casting and/or the very specific areas of the cylinder head(s) for a coolant leak from porosity. If the cylinder head(s) is a Castech casting (1), inspect the area around the five oil drain holes for witness marks indicating coolant seepage over time (2). Important: If No evidence of coolant loss is found on inspection of Castech casting cylinder head (s), follow normal diagnostic procedures in SI to determine the cause of the coolant loss

TOYOTA G52, G54, W56 & G58 (AX5) 5 SPEED TRANS. TO CHEVY AND BUICK ENGINES INSTALLATION INSTRUCTIONS:

download
This bellhousing is not compatible with transmissions that were previously equipped with diesel engines. The bellhousing design incorporates a special modified clutch release lever and a Toyota Land Cruiser slave cylinder. We have provided slave cylinder mounting on the passenger side of the bellhousing and have incorporated a new push rod location that will provide a quick short travel of the clutch release mechanism. The kit does not include the Toyota Land Cruiser slave cylinder, Part No. 31470-60022. The bellhousing is designed for the 153 tooth flywheel application. If your block is equipped with a 168 tooth flywheel, you will be required to use a high torque starter without a nose cone to fit the bellhousing (P/N 22-0001). The bellhousing is compatible with the Buick flywheel that has 160 teeth. A slight modification may be required in the starter pocket area when using the Buick installation. The inside of the bellhousing uses a high profile Centerforce diaphragm clutch assembly. By using this pressure plate, you can be sure that the slave cylinder travel will be appropriate for obtaining a maximum clutch release. The release bearing, Part No. N1430, is a standard flat faced Chevy release bearing. The bearing must not have continual contact with the fingers of the clutch. Adjust the length of your push rod for clearance between the fingers and the face of bearing. In order to adjust the height of the release bearing, we recommend that you install the new bellhousing over the clutch assembly and onto the engine prior to assembling the transmission to the bellhousing. By doing this procedure, you will be able to install the clutch release lever, slave cylinder, slave cylinder push rod, and release bearing directly to the clutch assembly. The reason this is necessary is that there are variations as to the thickness of the flywheel which either raise or lower the fingers of the clutch as related to the release bearing. The push rod of the slave cylinder can be adjusted, to obtain the necessary clearance between the release bearing and clutch fingers. If the bearing is permitted continual contact on the fingers, then you will have premature release bearing failure. We do not furnish a rubber boot for the area between the bellhousing and clutch arm since it is too restrictive for the clutch arm movement. We believe that the location of the opening is such that any dust or other debris will have a hard time accessing the opening. If you anticipate water hazards, we would recommend a small rubber flapper that could be screwed to the outside of the bellhousing.
