Q: How Should You Replace the Cylinder Head Bolts and Reinstall the Cylinder Heads in V8 engine on GMC Canyon?
A: For this process it will be necessary to procure a new set of 11 mm cylinder head bolts. This should be followed by reducing the pressure on the fuel system, pulling the cable connection on the negative terminal of the battery and for final drains, draining the cooling system. Disconnect the intake manifold gasket, make necessary modifications in the coolant pipe and unbolt the exhaust manifold from the cylinder head but don't take it off from the exhaust pipe. Secondly, take off the valve cover(s), further, depending on the model, the Rocker Arms and the Pushrods will be removed; it is pivotal to preserve all of the separate components for the assembly process. Firstly, un-bolt the coolant air bleed pipe, secondly, go towards the left cylinder head and to get there, do away with the alternator and the bracket holding it; this entire piece can be shifted forward; the ground strap on the other side of the head can now be detached. For the right cylinder head, if any, then take off the dipstick tube and the heater hose bracket from the front side of the cylinder head. Remove the head bolts in reverse order by rotating them counterclockwise in 1/4 turns as required until they are easily accessible and can be unscrewed by hand with attention made to the different lengths and sizes of the bolts so as to adopt the correct size and length in replacement. Carefully remove the head(s) from the engine if there is some sort of resistance then use prybar or a long screw driver on the intake port. always keep the heads on wooden blocks to avoid damaging the gasket ports. During assembling there must be no particles of carbon and the old gasket remaining on the mating surfaces of the cylinder heads and block, to remove them, use gasket removal solvents as well as gasket scraper, and do not forget to clean them with the brake system cleaner moistened cloth. Inspect the block and head mating surfaces for any imperfection, this will require light emery cloth for the minor imperfections and excess may require a machining. Clean the threads in the head bolt holes by either running a tap of the right size over the holes, or using brake cleaner and blowing off with compressed air. Align the new gaskets on the dowels in the block, fit heads onto the block in a manner which will not disturb the gaskets, and, before tightening the 8 mm head bolts, apply a medium strength, thread locking compound to the threads. Replace the former 10 mm head bolts with new ones of 11 mm which should be tightened by hand before using the recommended sequence to tighten the bolts to four quantities not less than the recommended torque. Screw the coolant pipe with new gasket to the cylinder heads and tighten the bolt to the torque. Replace all components in the reverse of the removal procedure, fill coolant, replace the oil and filter, start the engine and test for effectiveness and leakage of coolant or oil.
