Download Draining 1. Bring the engine to normal operating temperature and turn the engine off. With the cooling system under pressure, inspect cooling system hoses and clamped hose connections for leaks, excessive deterioration or contact wear. Inspect radiator installation retention. Note any discrepancies and proceed. 2. WARNING: Never remove the pressure relief cap while the engine is operating or when the cooling system is hot. Failure to follow these instructions can result in damage to the cooling system or engine or personal injury. To avoid having scalding hot coolant or steam blow out of the degas bottle when removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, (still with a cloth) turn and remove the pressure relief cap.… Read More

Download Installation is the same as for original equipment cylinder heads. Consult service manual for specific procedures, if necessary. Be sure that the surface of the block and the surface of the head are thoroughly cleaned to remove any oily film before installation. Use alcohol or lacquer thinner on a lint-free rag to clean. Apply oil or suitable thread lubricant to head bolt threads and the underside of bolt heads and washers to prevent galling and improper torque readings. Use thread sealant on any bolts that go into coolant passages. Torque top row of bolts to 110 ft./lbs. and bottom row of bolts to 100 ft./lbs. in three or four steps, following the factory tightening sequence (See Figure 1) . A re-torque is recommended after the initial star-up and cool-down (allow 2-3 hours for adequate cooling). Other Assembly Tips: When installing the sparkplugs and exhaust manifolds, be sure to use a high temperature anti-seize compound on the threads to reduce the possibility of thread damage in the future.… Read More
Download 1. Fully clean the cylinder head intake flanges and the engine block end seal surfaces. 2. Apply Edelbrock Gasgacinch sealant PN 9300 to both cylinder head flanges and to the cylinder head side of the gaskets, allow to air dry, and attach the intake gaskets. (Refer to instructions on Gasgacinch can for further reference). If you are using two-piece gaskets with a seperate tray, the valley pan will contact the cylinder heads with the gaskets resting on top. Both sides of the gaskets and pan should be coated with a layer of Gasgacinch. 3. Do not use cork or rubber end seals. Use RTV silicone sealer instead. Apply a ¼” high bead across each block end seal surface, overlapping the intake gasket at the four corners. This method will eliminate end seal slippage. 4. Install the intake manifold and the intake manifold bolts with hardened steel washers between the manifold and the bolt heads.… Read More

Download DESCRIPTION The liquid cooling system consists of a radiator, water pump, thermostat, electric or belt-driven cooling fan, pressure cap, heater, and various connecting hoses and cooling passages in the engine block and cylinder head. MAINTENANCE DRAINING Remove radiator cap and open heater control valve to maximum heat position. Open drain cocks or remove plugs in bottom of radiator and engine block. In-line engines usually have one plug or drain cock, while “V” type engines have 2, one in each bank of cylinders. FLUSHING Radiator Connect flushing gun to water outlet of radiator. Disconnect water inlet hose. To prevent flooding engine, use a hose connected to radiator inlet. Use air in short bursts to prevent damage to radiator. Continue flushing until water runs clear.
