Before the removal of the cylinder head, reduce the fuel system pressure and then detach the connection of the negative terminal of the battery. First turn off the water and use the drain to empty a coolant, then remove the drivebell and the drivebelt tensioner. Then remove the exhaust manifold (catalytic converter), and at last-the intake manifold. If you are working on 2015 and later CR-V models, rip off the fuel rail, fuel injectors, and the high-pressure fuel pump. Move forward and remove the timing chain, the camshafts as well as the rocker arm assembly. Some electrical connectors on the cylinder head might hamper its removal; label and remove these connectors, and separate all the coolant hoses you locate. The cylinder head bolts need to be loosened following a specific sequence, old bolts discarded and the cylinder head has to be raised off the engine. If there is any resistance then it is advisable to use wood block and hammer for loosening and ensure do not pry on the mated surface. Place the cylinder head on wooden blocks in order not to dent it, then pull of the old gasket. To install part, clean the areas where the mating surfaces are going to make contact with a gasket scraper and brake cleaner In addition, one has to cover several areas of the engine if they are open in order to avoid entry of contaminants. You should also look out for any signs of damage anywhere on the mating surfaces and then use tap to scrape the threads as those seen on the bolt holes. Align the new gasket into the correct place, fit the cylinder head to block without shifting the gasket and use new bolts to fasten the head in the prescribed manner, using the torque angle. Install the rocker arm assembly, camshafts, timing chain and cover, exhaust manifold, and intake manifold, as follows: Last but not least, connect the battery back, replace the engine oil and oil filter, refill the cooling system, and turn on the engine adding a note to check for such indications as existence of oil/coolant leakage.

Remove the spark plugs, disconnect the heater hoses, air filter housing, and intake resonator, then remove the drive belts.
